[00011 This application claims the benefit of U.S. Provisional Application 63/106,648, titled “TEXT-DRIVEN EDITOR FOR AUDIO AND VIDEO ASSEMBLY”, filed October 28, 2020; and U.S. Provisional Application 63/106,649, titled “TEXT-DRIVEN EDITOR FOR AUDIO AND VIDEO EDITING”, filed October 28, 2020.

FIELD OF THE TECHNOLOGY DISCLOSED

[0002] The disclosed technology generally relates to a computer-implemented methods, systems, and computer programs for video editing and assembling a video program. More particularly, the present disclosure relates to a method, system, and computer program for editing and assembling a video program based on keywords or sound bites derived from the transcribed speech in the audio tracks of video clips.

BACKGROUND

[0003] The subject matter discussed in the section should not be assumed to be prior art merely as a result of its mention in this section. Similarly, a problem mentioned in this section or associated with the subject matter provided as background should not be assumed to have been previously recognized in the prior art. The subject matter in this section merely represents different approaches, which in and of themselves can also correspond to implementations of the claim technology.

[0004] Video editing is the process of editing segments of video footage, video clips, special effects, and sound recordings into a finalized video program. In the past, nonlinear video editing (NLE) has been performed on complex and expensive dedicated machines with dedicated software, but over time video editing software has evolved to be widely available for use on personal computers and an even computer tablets and smart phones. The need for video editing software has grown over the last decade as more social media video platforms have become widely available incorporating video. The exponential growth of social media video platforms has resulted in a corresponding growth in content creators who are generating video content, editing that video content, and uploading the video content to the social media video platforms and elsewhere.

[0005] In professional video editing, the computer programs are expensive and complex, requiring that the user be trained in the use of a generally complex user interface. To become adept, users of nonlinear video editing must acquire an expert level of knowledge and training to master the processes and user interfaces for nonlinear video editing systems. Known nonlinear video editing systems can be intimidating for the general user because of the complexity.

[0006] Moreover, such computer programs are computationally inefficient. For example, such computer programs waste processing resources, as well as memory resources, in generating copies of videos during editing. To illustrate, in response to user commands to generate a video clip taken from a larger digital video, existing computer programs will often either 1) copy frames out of the digital video to generate a standalone video clip, or 2) duplicate the entire digital video then delete video frames not included in the video clip. As such, existing computer programs waste large numbers of processing cycles while simultaneously causing memory usage to quickly balloon in connection with video editing tasks.

DETAILED DESCRIPTION

System Overview

[0065] The present technology allows a user to edit and assemble a video program from transcribed text. In one aspect, the present technology is implemented as a browser-based or web-based application which includes cybersecurity features. The remote user uploads video files or video clips to an application server. An application server imports the video files or video clips to a storage device. For the purposes of this disclosure, video files or video clips generally include a file containing a synchronized audio track and a video track, along with metadata of various kinds including frame rate, image resolution, and timecode. The audio track and video track a synchronized by timecode. Each frame of audio is synchronized with each frame of video with the same timecode or timestamp.

[0066] The video track includes a sequence of images where each image is a frame operating at a known frame rate. Video clip also includes an audio track which carries the audio for sounds represented in each frame of video. Customarily, the audio track will include the vocal speech of a person or persons shown in the video track. The sounds in the audio track are synchronized to the images in the video track. A video file normally consists of a container containing video data in a video coding format alongside audio data in an audio coding format. The container can also contain synchronization information and various metadata.

|0067] In one example, the disclosed technology is a browser-based transaction system. The user pays a fee for using the host editing and video assembly facilities, with the cost based on the duration of the audio video editing session or other metrics. Or the host editing facilities may be provided on a subscription basis.

[00681 The technology has the capability of assembling a new video program. The features include video program editing, annotating, collaborating and then exporting to Microsoft Word, subtitles, Adobe Premier, Final Cut Pro, Avid Media Composer, and other nonlinear editing applications (NLE) and related applications for providing effects, captioning, titling, etc.

[0069] A user interacts with the first and second panels of the user interface by selecting text from a transcript of a selected resource in the first panel, dragging and dropping it onto the second panel, which causes the application to create a new clip. The order of clips can be arranged by the user by dragging and dropping clips.

[OO70| The editing and assembling of a video program proceed in phases. In the first phase, uploading and transcription, video files are uploaded from the user’s device or cloudbased storage account to the website and stored in application’s video storage, much like the video storage bin a nonlinear editing system. The audio track is extracted and undergoes a speech-to-text transcription, converting spoken voices in the audio track into transcribed speech in the form of formatted text, which is editable and searchable. A lengthy audio track can be transcribed efficiently in a short time. The transcribed text is displayed in the text window on the user’s video device. When multiple speakers are involved, the software is capable of automatically assigning speaker identification headings to the various speakers. [0071] The user has the capability of editing the text and adding comments and annotations to the transcription. The video is accurately synchronized to the text representation using timecodes. Every text word has associated timecodes, and every video frame has timecodes synchronized to the text words.

[0072] In the next phase, the transcribed text is displayed in a text window in the user interface, alongside a video window that displays the video corresponding to the text display. If the cursor is moved to a particular point in the text display, highlighting a particular word, the corresponding video frame is displayed. If several words or sentences are highlighted in the text display, the corresponding video may be played in a video window. The text may be searched, as in a conventional word processor, and text selections may be highlighted. The highlighted text selections or text segments may be moved to a video timeline portion of the display. The video timeline shows the selected text along with the thumbnail icon of the first preview frame of the corresponding video segment.

[0073] In one aspect, the disclosed technology is a text-based video editor using spoken informational content. The system provides asynchronous transcription of the audio track in a video clip. The video editing process begins after the initial step of transcribing and editing the text from the audio track. A timecode is associated with every spoken word. Segments of speech are identified by in-and-out timecodes. The transcribed text can be word-searched to locate soundbites, which are used in the assembly of a video program. The video assembly editor is based on text-based editing and assembly. The disclosed technology generally uses short video segments for quick and easy program assembly. Segments can originate from the same media or video file or combination. A preview video can be assembled and exported for post-processing to a finishing nonlinear editor such as Avid media composer, Adobe Premier, or Final Cut Pro to produce a fine cut video program.

[0074| As such, the disclosed systems and methods solve many of the technical problems presented by existing video editing computer programs. For example, the disclosed systems and methods increase the efficiency of a computing system by avoiding the processing memory waste common to existing video editing computer programs. To illustrate, and as will be discussed in greater detail below, the disclosed systems and methods present a browser-based solution where video clips are generated based on time codes synchronized across a digital video and a corresponding transcription. Accordingly, in response to a user selection of one or more words of the transcription, the systems and methods identify time codes corresponding to those words and utilize the identified time codes to play back portions of the digital video as video clips. Thus, the disclosed systems and methods generate clips of the digital video without also generating a copy of any portion of the digital video — thereby saving the computing resources that would have otherwise been wasted.

Transcription of Audio Track Into Text

[0075J The speech-to-text transcription disclosed may be based on machine learning or deep machine learning algorithms that select a speech recognition engine from multiple available recognition engines for accurately transcribing an audio channel based on sound and speech characteristics of the audio channel. A method and system of this type is disclosed in US Patent Application Ser. No. 16/373,503, which is hereby incorporated by reference in its entirety for all purposes. The technology disclosed and the incorporated application relates to a machine learning based speech-to-text transcription method and system that selects one or more speech transcription engines from multiple available speech recognition engines to provide the most accurate transcription of speech from an audio channel based on sound and speech characteristics. Any other speech-to-text transcription programs may be used, as long as they provide an output of high quality and high accuracy text from the video track in a video clip.

[0076] As used herein, the term “video” or “digital video” refers to a digital media item including a visual display with sound. For example, a digital video can include a video track and an audio track. In one or more examples, the video track can include a sequence of video frames where each video frame includes a digital image captured according to a predetermined frame rate and resolution. Additionally, in one or more examples, the audio track can include sounds represented in a digital medium. In at least one example, the video track and the audio track of the digital video are synchronized according to corresponding time codes.

[0077] In one or more examples, as mentioned above, the present system can generate a transcription of the audio track of a digital video. As used herein, a “transcription” refers to a written or printed representation of the sounds in an audio track of a digital video. For example, in the event that the audio track includes spoken words, the present system can generate a transcription including a digital written representation of the words spoken within the audio track.

Video Editing Workflow

[0078] The most accepted method of video editing workflow is the creation of a roughcut followed by a fine-cut. In the creation of an audio/video project, leading to a final program, it is the accepted process to first create a version of the video that shows the main features fit together in a sort of global view. This is called a rough-cut. In rough-cut form, collaborators may comment on the video, offering suggestions for improvement. It is much easier to work with a rough-cut, which can often be assembled in minutes and in a form wherein changes can easily be made. Once all the major components are laid out in a viable form, the video editing workflow proceeds to the next stage in the process, which can be thought of as fine-tuning, which would include performing transitions, adding visual effects, sound editing, inclusion of captions - anything that brings the video project closer to its final form. The disclosed technology supports this workflow by providing text-based video program assembly. The making of a rough-cut video has typically been a collaborative effort, which involved the cutting out printed transcript and having teams re-order the cut transcript on a whiteboard. The present technology streamlines this process using the video editing workflow described herein.

Assembling A Video Program With Multiple Speakers

|0079] One application of the present technology is the assembly of a video program in which multiple persons are interviewed about a specific subject, and the individuals present their views on camera. Often times, in answer to an interviewer’s questions, the interviewees present viewpoints on the multiple topics. The problem of the video program editor is to bring together a coherent video program, in which the subjects discussed are organized by topic. This requires editing the video program to show comments on the same topic, before moving on to a different topic.

|0080] With conventional video editors, this is a very complicated operation in video cutting and video assembly, where the user must digitally clip small video segments and move them around. The user makes individual decisions about where to clip the video segments and organize those segments that will make up the final program. This can be an unwieldy process with a conventional video editing system, even to produce a rough-cut which can later be refined. Basically, if there are three or more speakers commenting on multiple subjects, the video will need to be clipped and sequenced multiple times in order to make a coherent program.

[0081] With the present technology, the desired result is easily achieved. After the transcription phase, where the voices of the different speakers are transcribed into text form, the speakers’ names may be automatically applied labeled to assist in searching and locating relevant text and content. As used herein, a “speaker” refers to an entity that produces sounds represented on an audio track of a digital video. For example, a speaker can be a human who speaks words. In additional examples, a speaker can be a digitally generated voice that speaks words. In one or more examples, a speaker corresponds with various vocal characteristics (e.g., volume, tone, tambor, pitch, tempo) that the present system and method utilize to identify speakers within an audio track.

[0082] Word processing methods may then be used on the transcribed text to locate relevant content pertaining to a particular question posed. The editor may select the relevant content for each of the multiple speakers in this will be stored in a video content bin. With the disclosed technology, the video assembly editor may be used to easily create a visual timeline that shows the spoken words of each speaker in a chosen sequence. The individual soundbites may be arranged in a simple manner on the timeline to assemble a rough-cut of the video program. The program can be previewed and also be previewed by authorized collaborators, who may provide comments and suggestions after viewing the rough-cut video program. Automatic Tagging Of Speakers’ Voices

|0083] In one aspect of the present technology, the system provides tagging of speaker’s names. The program detects features associated with the speaker’s name to provide labels in the transcribed text that identify a speaker by the attributes of the speaker’s voice. Using these speaker labels, the text transcription may be searched, for transcribed text that is associated with a particular speaker. One advantage of this feature allows all the video segments associated with a particular speaker to be grouped together by the corresponding video timecodes to assemble a rough video program comprising video segments associated with a single speaker. For example, in an interview, it may be advantageous to bring together, all the comments made by a particular speaker in one series of concatenated video segments without including the segments associated with the interviewer. This is a very fast way of assembling the rough-cut of only those video segments associated with a specific interviewee.

[0084] As just mentioned, in response to determining that words or text within a transcription correspond with a particular speaker, the systems and methods described herein can assign add a speaker tag to the transcription that identifies the speaker. As used herein, a “speaker tag” refers to any indication within the transcription associating one or more words in the transcription with a speaker from the audio track of a digital video. In one or more examples, speaker tags can include automatically generated identifiers (e.g., “Speaker 1,” “Speaker 2,” etc.), manually input names (e.g., provided by a user in connection with the transcription), icons, colors, or any other suitable identifier.

System Architecture

|0085] The following describes in architectural form implementations for a browserbased video editing and video assembly method and system 100, which is intentionally simplified to improve clarity in the description. FIG.l shows the interconnection of the various major elements. The use of these elements will be described in greater detail further on in connection with the discussion of the structure and use of those elements.

[0086] FIG. 1 includes a system 100 including a host computer 110 for the browser based application. User endpoints may include devices such as desktop and laptop computers 130, smart phones 128, and computer tablets 126, which provide access to a network 122 to interact with data stored on a cloud-based store 124 and network access to host a computer 110. A user’s video files may be stored locally in the user’s remote device 126,128,130 or in cloud storage 125 accessible through a cloud-based service 124 or locally to the user. Video files may be retrieved from cloud storage 125 and uploaded to the host computer 100 and video editing application 114. The video application is resident in the application server 114. The application server 114 has access to video editing resources 116 and also to audio/video storage bin 122, which stores the user’s uploaded files.

[0087] Additionally, remote computers, tablets, and smart phones may have access through the network 122 to the application 114 as authorized collaborators. As part of the video editing and video assembly method, users 134, 136, 138 may be specified as reviewers and authorized to provide comments or editing suggestions to the finalized video program, as will be described. The authorized collaborators may review the video and comment in virtual real-time, so that the commentary may be received by the user while the video program is being finalized.

[0088] Cloud-based services 124 and cloud-based storage 125 provide the end users with a convenient method of storing video files, which may be uploaded to computer 110, and in particular to audio/video storage bin 122, to provide the raw video clips which will be used for the assembly of a finished video program.

[0089| The interconnection of the elements of system 100 will now be described. The network 122 couples the computers 130, smart phones 128, and the computer tablets 126 with each other.

[0090] The communication path can be point-to-point over public and/or private networks. The communication can occur over a variety of networks, including private networks, VPN, MPLS circuit, or Internet, and can use appropriate application programming interfaces (APIs) and data interchange formats such as Representational State Transfer (REST), JavaScript Object Notation (JSON), Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), Java Message Service (JMS), and/or Java Platform Module System.

[0091] Communications may be encrypted. The communication is generally over a network such as the LAN (local area network), WAN (wide area network), telephone network (Public Switched Telephone Network (PSTN), Session Initiation Protocol (SIP), wireless network, point-to-point network, star network, token ring network, hub network, Internet, inclusive of the mobile Internet, via protocols such as EDGE, 3G, 4G LTE, Wi-Fi and WiMAX.

[0092] The system components of FIG. 1 are implemented by software running on varying types of computing devices. For example, a workstation, server, a computer cluster, a blade server, or a server farm. Additionally, a variety of authorization and authentication techniques, such as usemame/password, Open Authorization (OAuth), Kerberos, SecurelD, digital certificates and more, can be used to secure the communications.

|0093] The cloud-based services 124 provide functionality to users that are implemented in the cloud or on the Internet.

[0097] FIG. 2 illustrates the generalized workflow of the disclosed technology for a system for assembling a video program using transcribed video soundbites, and FIG. 3 illustrates the workflow in more detail.

[0098] In FIG. 2, a user’s audio/video files 150 are uploaded from the user’s remote device 126, 128, 130 or from a cloud-based video store 125 associated with a cloud-based service 124. The uploaded files are stored in an audio/video storage bin 122. A transcription engine 152 transcribes the audio track associated with the video clip to provide an accurate text transcription of the audio track synchronized to the audio and video track via time codes. For example, the transcription engine 152 assigns time codes to the transcription by identifying time codes at increments within the audio track of a digital video (e.g., according to the frame rate of the digital video) and assigns those time codes to the transcription at the same increments. To illustrate, if the frame rate of the digital video is 30 frames per second, the transcription engine 152 can identify 30 time codes for every second of the audio track of the digital video. The transcription engine 152 can then assign the same time codes to text within the transcription representing the sounds occurring over the corresponding increments of time (e.g., 30 increments per second).

100991 The transcription engine 152 may be operated independently of the editing and assembly module as a separate service, to provide accurate transcriptions of audio content, such as video interviews, on a pay-as-you-go or subscription basis.

[001001 When a new editing and assembly project is initiated, the user’s transcribed text files are transferred into the application’s video assembly editor 154, where a finished video program is assembled. The video assembly editor 154 is a graphical user interface and a set of user tools for creating a video program from the user’s uploaded video files 150. The disclosed technology uses the transcribed text to select and sequence video segments into an assembled video program. Using text transcriptions of the audio track, the user selects segments (e.g., one word, multiple words) of text, and drags and drops onto a visual timeline in a chosen sequence. The video frames and audio frames associated with the selected text and moved to the timeline along with the text. The assembly editor 154 allows the user to experiment with different cuts and sequences to assembly of video program. The resultant video program may be a rough-cut video program in which various video segments are assembled in proper sequence. In this case, the user may export 158 the rough-cut video program to a secondary video editing system such as Avid media composer, Adobe Premier, Final Cut Pro, to provide finishing touches to the rough cut and arrive at a fine-cut version. In another example, the uploading may occur directly from the application’s video assembly editor and the transcription engine may be operated as component of the application’s video assembly editor.

[00101] In some uses of the disclosed technology, the video assembly editor 154 will produce a completed video program, without the need for post-processing in a nonlinear editor.

[00102] The application provides a collaboration interface 156 for authorized collaborators to sign into the application, play the assembled video, and provide comments to the user while the video is being assembled. This may occur in virtual real-time, so that the comments will be received while the video is still being assembled by the user.

[00103] As used herein, the term “video clip” refers to a segment of a video track and corresponding segment of an audio track from a digital video. A video clip typically includes a plurality of sequential image frames and an audio track associated with the video clip, by time code, and other metadata, such as resolution and frame rate. The audio track typically includes a speaker or speakers’ vocal track comprising spoken words and sentences.

[001041 As part of the first phase, the audio track is transcribed into text comprising a plurality of text segments, wherein the text segments map to a plurality of video segments. The audio frames and image frames per segment are always synchronized.

100105] In FIG. 3, the process of assembling a video program is shown in more detail with reference to a single video clip 150, video file, or digital video. The source video clip 150 is selected by the user for processing by the system. The source clip 150 includes a video track 310 and the corresponding audio track 315. The video file also contains metadata in the form of frame rates, video formats, video resolutions, and time codes. Source video clips 150 may be in various video formats, with various frame rates and resolutions. For example, input video 150 may be one of several standard frame rates including: 24, 25, 30, 50, 60, 2398, 2997, 2997 DF, 5994, and 5994 DF and other known frame rates. In FIG. 3, synchronized video/ audio time codes are maintained throughout the process of video assembly. The video clips 150 may be encoded in any popular format. An example would be MPEG-4 video clips, which is a popular form of lossy video compression encoding. The technology disclosed accommodates all popular video formats.

[00106] Each uploaded video clip 150 is stored in the user’s video bin 122. The user may select one or more uploaded video clips 150 to be dragged and dropped into the video assembly editor 154 to create a new video program.

[00107] As illustrated in FIG. 3, the transcription engine 152 processes the audio track, providing a high quality audio-to-text transcription 325. Time codes 330 are maintained throughout, so that the individual words in the text transcript will correspond to audio soundbites as well as corresponding video frames. Using this method, a time code 330 is associated with each spoken word in the audio track 315. The text words may be edited, selected, copied, and moved as in a conventional word processing program. Selected text is always associated with corresponding audio and video by the time codes 330. Synchronized Timecodes

[001081 Timecode is a video synchronizing standard which is based on a 24-hour clock readout. Each frame of video assigned unique timecode value. The timecode 330 is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production applications which require a temporal coordination of elements related to video frames and audio frames.

[00109] Basic time-code standards assume a video frame rate of 30 frames per-second or 25 frames per-second, depending on the country. The NTSC video standard used principally in the United States and some other countries has a frame rate of 30-frames per second (fps), and PAL and SEC AM, used mostly in Europe, has a frame rate of 25-frames per second (fps). In NTSC, 30 frames equal one second. Video in color or DTV/HDTV actually has a frame rate in the US of 29.97 fps. Synchronization between 29.97 fps and 30 fps timecodes are maintained by methods such as periodically dropping timecode frames according to a formula, known as drop-frame timecode. Generally in the disclosed technology, drop frame timecode’s are not used or required. In the present technology, additional frame rates may be used, including: 23.976, 59.97, 60, and other widely used frame rates.

[00110| Timecoding is also referred to as time stamping. One well-known type of timecode used in video production is SMPTE timecode. A SMPTE time code is used to identify a precise location on time-based media such as audio or video in digital systems. SMPTE refers to the standards organization Society of Motion Picture and Television Engineers.

The SMPTE standards actually describe a family of timecode encoding formats used in film, video, and audio production, including: Linear timecode (LTC), Vertical interval timecode (VITC), AES-EBU embedded timecode, Bumt-in timecode, CTL control track timecode (control track); and MIDI timecode.

[00111] Timecode (or time codes) is displayed in the format HH.MM.SS.FF (hours, minutes, seconds, frames). For example, if a video clip begins at timecode 14:34:01:22, this translates into 14 hours, 34 minutes, 1 seconds, 22 frames. In this way, each frame of a video track 310 and each frame of the corresponding audio track 315 includes a precise digital address.

[001121 In the technology disclosed, video assembly editor 154 tracks time codes associated with each spoken word in the transcribed text abstracted from the audio track portion of the audio/video clip. A high quality transcription is performed on the audio track so that each individual speaker’s audio is provided with the text transcription of the speech each speaker.

[001131 The transcription of a speaker’s each spoken word is correlated to the audio track 315 timecode and the video track 310 timecode in the video track, such that the video corresponding to each spoken word is identifiable in the text transcript 325 of the audio video track. The transcribed audio text is presented in a text window in the user interface and may be searched as in a conventional word processing program such as Microsoft Word.

[001141 As described further on in more detail, a video program may be constructed by selecting words and phrases in text form from the transcribed audio speech in the text window. These selected soundbites may be arranged in a video program window. The video segment corresponding to the soundbites will be automatically selected and arranged on a timeline.

[00115] The video program is assembled in video assembly editor 154 essentially by moving around text transcribed from the audio track 315.

[00116| In the video assembly editor 154, the user selects soundbites or text segments 345 in a text display window (e.g., a transcribed text window), using conventional word processing editing functions. The user moves the chosen soundbite text 345 onto a visual timeline 350. The clips represented on the timeline 355 may be reordered, at least by a drag- and-drop method, and trimmed to assemble a video rough-cut which can be exported in any of a large number of video media formats such as including H.264 MPEG-4, the most popular format. The fine cut or formal cut can be performed on a dedicated nonlinear editing system such as Adobe Premiere Pro, Final Cut Pro X, SRT Subtitles, Avid Media Composer, DaVinci Resolve, Avid Pro Tools, and Adobe Audition.

[001171 The transcribed text and video are always locked in synchronization by the associated timecode 330. If the user moves the text pointer to a different location in the transcribed text 325, the corresponding video in the video window jumps to the new location. [00118] Continuing now to FIG. 4, a flowchart illustrates the steps for assembling a video program from user-provided video clips 150. In step 400, a video clip 150 (e.g., a digital video) or clips is received into the system as source material for creating and assembling a video program 360. In step 410, the audio track 315 for the clips 150 are transcribed using a transcription engine 152 to produce a high-quality searchable text transcript 325 of the audio track 315. In step 420, the user selects soundbites 345 from the searchable text displayed in the user interface display panel. In step 430, the user drags and drops selected soundbites onto a visual timeline 350. In step 440, the user arranges the selected soundbite text 345 in a desired presentation order to form an assembled video program 360. In step 450, the user previews the video program 360 and allows comments from authorized collaborators. In step 460, the assembled video program 360 is exported to a nonlinear editing system 365 for additional fine cut processing.

[00119] FIG. 5 shows a display screen of a graphical user interface 500 as viewed during the creation of a video project. In FIG. 5, transcription of a video clip 150 (FIG. 3) has already been performed and is presented in a text display panel 506. The video window 502 is shown, which displays video frames corresponding to the transcribed text. In this part of the user interface, the video window 502 (e.g., a video playback window) includes playback controls 504 for controlling the playing of the video clip 150. In the text panel 506 to the right of the video window 502 the text corresponding to the video is displayed. The user interface screen shows that the video clip 150 may be played, the corresponding audio track 315 displayed, and the transcribed text 325 may be displayed. The video frames, the audio frames, and the elements in the text transcript are all synchronized by timecode.

[00120] The transcribed text 506 is structured by timecode. The spoken text is divided into text segments 508 or paragraphs, and each text segment is provided with visual timestamp 510 that indicates a time code associated with each text segment 508. The time stamps (00:22) 510 are derived from the transcript map shown in FIGS. 6 and FIG. 7, as will be described. The time stamps 510 provide a convenient way to locate specific text segments 508 in the transcription. For example, in a long video clip, the time stamps 510 provide a convenient way for searching through a lengthy transcript to locate specific content, along with the corresponding video 502 and the corresponding audio.

[001211 Also shown in the upper part of the display 500, the audio waveform 512 corresponding to the audio track 315 is shown. Any selected point in the audio waveform 512 will correspond to a text segment 508 and also to the corresponding video segment 502. The user may scroll through the audio waveform 512 waveform to select and play a particular segment of the audio track 315 for that video clip 150.

The Transcript Map

[00122] Turning now to FIG. 6, a transcript map 600 is created when the audio track 315 is transcribed into text. As used herein, the term “transcript map” refers to document or data structure that associates two or more types of data. More specifically, a transcript map can include a data structure (e.g., table, index, comma separated list, hash table, linked list) that associates time codes with words from the transcription of an audio track of a digital video. The transcript map 600 provides numerous identifiers for the transcribed text corresponding to a video clip 150. The transcript map includes file identification information. The transcript map 600 shows status information related to the video clip 150, the transcription language, the frame rate, the start timecode 610 and the end timecode 630 for that transcribed text segment 508. The transcript map 600 also identifies the first word in the text segment 508. In the case where there are multiple identified speakers, the transcript map identifies those speakers.

[0123] In FIG. 7, the transcript map 700 shows the breakdown of the start time code 710, the end time code 720 and the value for that time code range, which is the text element associated with that time code segment. FIG. 7 illustrates how the system associates every text element (individual word), with a time code by start time code 710 and end time code 720. In this example, the text element “there’s” corresponds to the start time code 710 and the end time code 720. In other words, the disclosed systems and methods identify all the time codes that correspond with the word “there’s” in the transcript map and assigns the first time code associated with “there’s” as the start time code 710 and the last time code associated with “there’s” as the end time code 720. In the event that a particular word occurs more than once in the transcript, the disclosed systems and methods can associate more than one group of time codes with the same word. In that example, the disclosed systems can determine start time codes and end time codes for the word by identifying a start time code and an end time code in each group of time codes associated with the word in the transcription map. Because timecodes are associated with each text elements, rather than video frames, the time codes follow a structure which is modified from traditional timecode structure, the final number having 999 divisions of time, rather than the conventional 30 frames per second.

[0124] In this illustration, the time codes track five spoken words in succession by the start time code and the end time code. The spoken word “I” is associated with the first text element. The spoken word “think” is associated with the second text element. The spoken word “there’s” is associated with the third text element. The spoken word “a” is associated with the fourth text element. And the spoken word “general” is associated with the fifth text element. Together, the spoken phrase is “I think there is a general” in which each text element as a very specific start time code and end time code. The editing application tracks all of these individual text elements and the values of each text element. As is shown in figure 7 the time code increments by an amount equal to the time required for text element to be spoken as a segment of the audio track 315. FIG 7 is illustrative of how the application software logs individual word in the transcript. Selection of a particular word in the text display will bring the video to that point in the transcript and the associated video frames associated with that particular word in the text display will be queued up. In a similar manner, the audio waveform 512 corresponding to that particular text element will be shown in the display at the top of the user interface.

Video Assembly Editor

[0125] FIG. 8 shows a video assembly interface 800 as used in the disclosed technology. In the leftmost panel, an import function 810 provides the user with the ability to import videos from various sources which may include cloud storage applications. Once the uploading of video clips is completed, for new project, the user may display a listing of imported video clips entitled “My Videos.” These are all the imported video clips that are available for assembling the user’s new video project. Also on the leftmost panel of the user interface, a video window 502 is displayed along with the text window 506 showing the transcribed text from the audio track 315. The video frames and transcribed text words are synchronized through timecode.

[0126] The rightmost panel in the user interface shows 800 the graphical elements that are used in the assembly of a new video program. A video window 820 is located in the topmost area of the display. The video window 820 includes play 830 and pause 832 controls. Below this video window is an open area 840 for the video timeline 842 as will be described. The video assembly timeline area 840 is the space where the selected soundbites and video preview thumbnails will be dragged-and-dropped and sequenced during the editing and assembly process.

[0127] FIG. 9 shows a video assembly interface 800 as used in the disclosed technology. In this view, the leftmost panel does not show a listing of imported video clips entitled “My Videos.” Although FIGS. 8-11, 13-15, 20-21 illustrate features of the video assembly interface 800 in certain arrangements, other arrangements are possible. For example, the video assembly interface 800 includes additional features (e.g., a timeline archive), or fewer features.

[0128] FIG. 10 illustrates a screenshot of the selection screen for selecting a soundbite (e.g., one or more words in the text of the transcription) to be used in the assembly of the video program 360. A text segment 1006 of the transcript is selected by highlighting chosen text (e.g., by selecting one or more words in the display of the transcript) and choosing a positioning icon 1002 or 1004. These icons cause the selected text segment 508 to be moved to a particular playback position in the video timeline, which is also the playback position for the corresponding video segment 502. The video segments may be assembled and presented in any order on the video assembly screen, and the video segments may be reordered by selection of an icon 1002 or 1004.

[0129] If the user chooses for the text segment and corresponding video segment to be positioned between two previous video segments, the first icon 1002 is selected. If the user chooses for the text segment and corresponding video segment to be positioned at the end of the sequence of video segments, a second icon 1004 is selected. The selected transcribed text segment 1006 is shown highlighted on the text screen.

[0130] Turning now to FIG. 11, a screenshot of the video assembly interface 800 is shown in more detail. The video segment 502 corresponding to a transcribed text 508 is shown. The selected text segment 1006 of the transcript 508 is shown highlighted on the screen. Selected elements from the leftmost panel are moved to the assembly panel 840, or timeline area, by drag-and-drop actions. The ordering and reordering of text and video segments elements are likewise arranged by drag-and-drop actions. The order of presentation on the rightmost panel is again sequenced by dragging and dropping the selected text 1006. In the rightmost panel, a preview frame 1104 is displayed alongside the selected text 1102. The preview frame 1104 is a thumbnail of one frame from the video segment 502, corresponding to the selected text 1006.

[0131] The preview frame 1104 is displayed alongside the selected text 1102. The preview frame 1104 is similar to a thumbnail or head frame in video editing, providing a visual representation of the video clip as a guide to sequencing the video segments 502 in the assembly of the video program. It is a convenient way for the editor to reorder the clips by dragging and dropping during program creation. In the rightmost panel of the screen, the project name 1110 is shown alongside the timecode 1108 or timestamp associated with the last text element or video frame for that selection. From this point onward, the user may “click” the preview frame to play the video.

[0132] The user interacts with the program by user actions, which may include drag-and- drop actions. Selections of text segments 1006 and the associated video segments 502 are made by user actions, which may include by drag-and-drop actions. The order of the video segments 502 may be arranged and reordered by reordering commands, which may include dragging and dropping of clips. Reordering of clips is performed preferably by drag-and-drop actions, but other user reordering commands are contemplated.

[0133] FIG. 12A and FIG. 12B illustrate the timecode tracking for the selected text segment lighted selection 1006 selection shown in FIG. 11. Each selected word or text element is tracked with its associated start time code and end time code. For example, the text element “When” 1212 shown with start time code 1202, and the text element 1232 is shown with the end time code 1222. Every text element or word in the selected text segment 1006 is stored with its associated start time code and end time code.

[0134] As illustrated in FIG. 13 and FIG. 14, when the user makes a selection of a text segment 1006, the system accesses a media fragment uniform resource identifier (URI) 1300 of the video. As used herein, a media fragment uniform resource identifier refers to programming code that references a specific media item. In one or more examples, a media fragment URI is scripting code that causes a web browser to request a media item from a specific Internet location. A media fragment URI can reference media items including digital videos (e.g., “.mp4” digital videos), audio files (e.g., “.mp3, “.wav” audio files), or any other type of digital media item. As shown in FIGS. 13 and 14, media fragment URIs can further reference specific portions or segments of media items. For example, the media fragment URI 1300 is generated for the video segment corresponding to the selected transcription text and includes metadata associated with the selected video segment. The media fragment URI 1300 of the video segment 1104 identifies the start time code and the end time code of the last element. The structure of the universal resource identifier URI 1300 is shown in FIG. 13 and FIG. 14. In particular, in FIG. 14, the start time code 1402 and the end time code 1422 are indicated within the media fragment URI 1300.

[0135] FIG. 15 shows the selection and sequencing of multiple video segments corresponding to selected text segments. In FIG. 15, the user selects a second text segment 1502 and moves the text segment into the video assembly editor timeline 840. The first selected video segment 1104 is displayed in the user interface as a preview frame in the topmost location of the editor. The second selected video segment 1504 is positioned below the first segment 1104. The first segment 1104 is configured to play before the second segment. If a third video segment is selected, as defined by start time code and end time code, the third segment will be displayed below the first and second segments. A sequence will be generated to play the first, second, and third video segments in the order in which the first, second, and third selections are received.

[0136] FIG. 16 shows the callback functions. In one or more examples, the callback functions can be JavaScript callbacks. The callback functions use Hypertext Markup Language (HTML) to designate “on pause” events 1602. In at least one example, the present systems and methods incorporate “on pause” events to sequentially perform task or actions — each task or action initiating once a prior task or action has completed and entered into a pause state. The callbacks accept video identifiers 1604 that indicate the successive video segments and the order of their playback. The sequence is further configured to play the first, second, and third video segments in a second playback order prescribed by a reorder command 1606, as shown in FIG. 17. Successive video identifiers are updated in response to the reorder command 1606. The reorder command 1606 is a user interface action that graphically reorders the first, second, and third video segments in the sequence across a graphic interface.

[0137] FIG. 18 shows that the callbacks 1606 use hypertext markup language (HTML) “on pause” events and will play the sequence of video segments in response to a play command based on the updated successive video identifiers 1802, 1804. This second play command is based on updated successive video identifiers, which cause playback of the first, second, and third video segments in the second order.

[0138] FIG. 19 illustrates that the sequence is further configured to play a successive video segment among the first, second, and third video segments immediately upon completion of playing a current video segment. The sequence is further configured to use callback functions to play the successive video segment immediately upon completion of playing the current video segment 1904. In response to the reorder command, the successive video identifiers are updated, thereby chaining playback of the first, second, and third video segments in the second order.

[0139] FIG. 20 and FIG. 21 shows the user interface screens for the operational video assembly editor for selecting, sequencing, and playing video clips corresponding to transcribed text. The video player is configured to play a video in a video window 502. The transcript of the audio track 508 is graphically displayed and synchronized with frames of the video clip according to the transcript map. The user selects one of a plurality of text segments 1622 in the synchronized transcript 508 by highlighting the selected text in the display. The system is configured to play back the video segment 502 that is synchronized to the selected text segment 1622. The user selects text segments the text, and selected text 1622 is moved onto the video editor timeline 842.

[0140] The timeline 842 is configured to play back the successive video segments in order in which the text segments are dropped onto the timeline. The video corresponding to a text segment is displayed, showing the actual text along with the start time code and end time code of the text segment. A preview frame 1104 is displayed with the selected text segment along with an indication of the start time code and the end time code for the video segment. [0141] The playback function on the video player 820 includes a play/resume button 830. The video assembly editor plays the video segments in the order the text segments were selected. The player includes a play/resume button 830, and a pause button 832. The timeline 1650 is configured to, in response to the selection, to graphically render respective previews of the video segments in the order. The timeline 1650 of the video assembly editor is configured to graphically render text in the text segments along with their respective timestamps adjacent to the respective previews adjacent to the respective previews. A second text and video segment 1504 is positioned below the first selected segment 1104, and the third text and video segment 2004 is positioned below the second selected text and video segment 1504. A progress bar may be displayed under the video so that a user may see the playback position within the timeline. Also, the current playback position of collaborators may also be displayed. The user may also skip back and forth between segments or jump directly to one by clicking on the thumbnail 1104, 1504, and 2004.

[0142] In one or more examples, the disclosed systems and methods select the images in the thumbnails 1104, 1504, and 2004 by selecting a first video frame from the corresponding video clips. In additional examples, the disclosed systems and methods can utilize image recognition techniques to select the images in the thumbnails 1104, 1504, and 2004 by selecting a first video frame from the corresponding video clips that shows a specific object (e.g., a human face).

Operation of the Disclosed Technology

[0143] In creating a new project, the user drags and drops audio and digital video files, often in the form of MP4 videos by accessing cloud storage applications. The downloaded digital video will include an audio track, video track, and synchronizing timecode for the audio track in the video track. The first step is to transcribe the original audio into a transcription in a chosen language. In this form, a transcription text file is created which corresponds to the spoken words in the audio track. The disclosed systems and methods utilized mapped time codes to associate each word in the transcription with corresponding spoken words in the audio track and corresponding video frames in the digital video. The text transcription is in the original language in the audio track, but there is a provision to convert the text into other languages as a secondary step, as needed as well as muting the audio track during playback.

[0144] In the next phase, the video assembly mode, the video is cut by editing text. By selecting and sequencing the text representations of the soundbites from speakers voices, transcribed into text, the corresponding video is also sequenced on a graphical timeline. Once a rough-cut video is created from sequencing the video clips corresponding to the selected soundbites, other video editing operations are performed, such as removing time gaps, and bloopers, the video can be exported using a variety of export formats such as popular MP4. Subsequently, the rough-cut video can be further processed in a nonlinear video editing application.

[0145] In the speaker video resources, multiple speakers can be identified in a single transcript. Each digital video can depict one or more speakers. For example, digital videos featuring multiple speakers may recordings of video conferences. As such, the disclosed systems and methods can generate a transcription of such a digital video that identifies and indicates each of the speakers within the digital video.

[00146] A video conferencing center can facilitate generation of transcripts by marking in video recording original audio channel sources to help the transcription process distinguish among speakers and to recognize multiple speakers talking at the same time. This is practical during multi-speaker video conferences, leveraging the separate channel origins of separate speakers. Further, speaker identification can be annotated as captions in the video recording file for speaker channels based on speaker logins and channel origin attributes.

[00147] In more detail, the systems and methods described herein can extract an audio track from a digital video and transcribe the audio track while simultaneously analyzing vocal characteristics of one or more speakers featured in the audio track. Based on this analysis of vocal characteristics, the disclosed systems and methods can add speaker tags to the transcription that identify speakers associated with words or blocks of text within the transcription.

[00148] In one or more examples, the systems and methods generate the speaker tags as interactive controls. For example, in response to a detected selection of a particular speaker tag, the systems and methods can automatically highlight or selects all text within the transcription associated with the particular speaker tag. Then, in response to a detected drag- and-drop of the highlighted text onto the video timeline, the disclosed systems and methods can generate video clips or segments corresponding to each block or segment of highlighted text. In this way, the disclosed systems and methods enable easy creation of video clips associated with a single speaker depicted in a digital video — even when the digital video depicts additional speakers as well.

Removing Bloopers

[0149] A blooper may result in a recorded interview or informational video interview, when a speaker states something that is improper, embarrassing, or otherwise inappropriate for the context of the program. It is usually desirable to remove these “bloopers” from the video program. Selected content may be identified as bloopers by providing a listing of keywords to search. Additionally, the disclosed systems and methods may identify a specific keyword in the transcription as a blooper-word in response to a detected selection of a single instance of the specific keyword. The user may excise portions of the recording, both audio and video, by manipulating the words in the transcript based on this keyword search. The solution can be extended by training the transcription system to alert the user to a blooper keyword and the content immediately preceding the blooper keyword, so that the user may choose to delete the inappropriate content. For example, systems and methods disclosed herein can train a machine learning model to automatically detect any keyword based on user trends — as undesirable verbiage may change over time.

Removing Disfluencies

[0150] Also, the disclosed technology provides for the automatic removal of disfluencies. Breaks or disruptions in the flow of speech are labelled "disfluencies" and these encompass speech hesitations and irregularities such as “uhm’s” or pauses caused by stuttering. Disfluencies may be identified by detecting excessive pauses between spoken words or using a keyword list of known disfluency utterances. Once identified, the software may automatically delete the disfluencies from the transcript. Additionally, disfluencies may be detected by machine learning methods.

[0151] In more detail, the disclosed systems and methods can remove keywords (e.g., bloopers, disfluencies, or other types of words) in many ways. For example, the disclosed systems and methods remove a keyword by identifying a listing of pairs of start time codes and end time codes associated with the keyword in the transcript map. The systems and methods then utilize the listing to update a series of “on pause” statements in the HTML code associated with the video assembly interface. To illustrate, in response to identifying two instances of a keyword in a transcription of a digital video, the systems and methods can update or generate three “on pause” statements to include 1) a start time code corresponding to the beginning of the digital video and an end time code corresponding to the start time code of the first instance of the keyword; 2) a start time code corresponding to the end time code of the first instance of the keyword and an end time code corresponding to the start time code of the second instance of the keyword; and 3) a start time code corresponding to the end time code of the second instance of the keyword and an end time code corresponding to the end of the digital video. In this way, upon playback, the “on pause” statement effectively remove the keyword from the digital video. Collaboration Mode

[0152] The creation of a video program has been and continues to be a collaborative effort. The technology of the present disclosure provides for the originator of the project to share the project with other collaborators by inviting others to collaborate.

[0153] In one aspect, a user may invite others to collaborate and play the rough-cut video program. A collaborator may input security credentials into the application the user-interface, which allows that collaborator authorized status to provide near real-time commentary on a video program under development in the video assembly editor. For example, the user can request for unique security credentials to be generated and provided to the collaborator that are associated with a specific video project. In this way, the disclosed systems and methods can control a level of access granted to the collaborator.

[0154] Collaborators may view and approve the rough-cut, or make suggestions for alternatives or improvements, and actually create different versions. For example, collaborators may play back different versions to view alternative sequencing of video segments and provide comments or suggested edits the user.

[0155] In more detail, the disclosed systems and methods can create an additional version of a video time including video clips in one or more ways. In one example, the disclosed systems and methods can detect edits in connection with an original video timeline initiated by a collaborator (e.g., a user other than the author of the original video timeline). For instance, the systems and methods can detect edits including comments or annotations added to the original video timeline, reordering of the video clips within the original video timeline, and/or adding or changing transitions or fades between video clips within the original time. In at least one example, rather than permanently incorporating the detected edits into the original video timeline, the disclosed systems and methods can leave the original video timeline intact and generate a second video timeline that incorporates the detected edits. For example, the disclosed systems and methods can generate a second set of “on pause” events that reflect the detected edits in connection with the video clips of the original video timeline. The disclosed systems and methods can then generate an archive display in connection with the video assembly interface that provides access to the original video timeline and the second video timeline. In at least one example, the disclosed systems and methods can provide this archive display in real-time, such that the author of the video timeline can pick and choose which edits to incorporate while continuing to assemble the original video timeline. [0156] The creation of a video program has been and continues to be a collaborative effort. The technology of the present disclosure provides for the originator of the project to share the project with other collaborators by inviting others to collaborate. Collaborators may indicate approval or disapproval on the timeline with visual icons (emoji’s).

User Interface

[0157] In one aspect, the disclosed technology is a method and system for video editing and for assembling a video program implemented a dedicated website. The disclosed technology provides an enhanced user experience (UX) superior to competitive products The workflow is an easy-to-follow guided method for assembling a video program. The disclosed technology provides an enhanced user experience by simplifying the video program creation process which results in a final program that can be exported for post-processing or final processing in a dedicated video editing system.

[0158] Various competitive products have the drawback of not being user-friendly. It is known that when the workflow and user experience (UX) is complex, illogical, or non- intuitive, users can be discouraged from using the website at all. Providing the user with a pleasing user experience (UX), promotes further use of the website application. The user interface may support viewing transcripts for two interviews at the same time on multiple monitors to make cutting between subjects faster.

[0159] In another aspect, the timeline may be arranged by topics and nested sequences.

Particular Implementations

[0176] Some particular implementations and features for assembling a video program using soundbite-based editing are described in the following discussion. The disclosed technology is a time-saving way to produce a rough cut video using an intuitive user interface that requires no special training or tutorials for its use. In one disclosed implementation, the system and a computer implemented method are provided for assembling and editing of video program is based on spoken words and soundbites. The disclosed technology imports source A/V files over network and provides the user with a way as assembling and editing a video program from spoken words associated with the imported video files. The past nonlinear video editing has been performing complex and expensive dedicated machines with dedicated software. The disclosed technology brings video editing and the assembly of the video program within the grasp of most Internet users from remote locations using cloudbased applications or a network.

[0177] Video files generally consist of an audio track and a video track. This audio track and video track are synchronized by timecodes so that each frame of video is locked into frame of audio. In actuality, the audio track in the video track are synchronized. One frame of audio is associated by timecode to one frame of video. Video clip also contains other metadata of various kinds including frame rate, image resolution, along with the synchronizing timecode. Source audio/video clips may be imported in various formats such as popular format such as MPEG 4. The disclosed technology imports source audio/video clips and any of the popular video formats.

[0178] In one aspect, a video track including spoken audio with spoken voices is transcribed into searchable text by a speech-to-text engine. The text transcript appears as an editable text document. In the transcription process a timecode is associated with each transcribed word from the audio track. The words are mapped to the video, and every spoken word has an associated timecode, with a start timecode and a stop timecode. Each word of transcribed text has a corresponding start timecode and end timecode. Each spoken word corresponds to a timecode marker, which in turn corresponds to a video frame or frames. [0179] In one implementation, the transcribed text may be edited using conventional word processing operations and text editing functions. The text may be or searched by the use of keywords. By searching the corresponding text, exact fragments or soundbites can be identified in the transcribed text and selected as transcribed text segments. By selecting text and arranging text segments on a timeline display, a video program can be assembled on a timeline display. The video frames in the selected video segments correspond precisely to selected text segments. Multiple text segments may be selected by the user and move to the timeline by drag-and-drop actions and sequenced as a playlist. In this way, a video program is assembled which can be played back, while the user experiments until satisfied with the final sequence which can then be exported as a complete program or as a rough cut video program which can be exported to a dedicated nonlinear editing system or application for fine cut finishing. The disclosed technology can be used to assemble a video program on a timeline display in any chosen order by the user. The sequence of video segments may be ordered, reordered, and edited, as desired. Sequences can be changed along within the video segments themselves, until the user is fully satisfied with the composition of the video program, and the user is ready to export.

[0180] In the assembly of a video program, the disclosed technology allows the user to engage authorize collaborators to view the video project as it is being assembled. Authorized collaborators can log on and play the video, provide comments on the project, provide suggestions for alternatives for improvements, or simply provide positive indicators in the form of emoji’s.

[0181] The method described in this section and other sections of the technology disclosed can include one or more of the following features and/or features described in connection with additional methods disclosed. In the interest of conciseness, the combinations of features disclosed in this application are not individually enumerated and are not repeated with each base set of features. The reader will understand how features identified in this method can readily be combined with sets of base features identified as implementations.

[0182] In another aspect, the present disclosure provides a very fast way to search for relevant content. The alternative is to view an entire video and audio track, which can be time-consuming, even when viewed at faster than real-time speed. By using transcribed text which can be searched, locating relevant text is expedited. It’s no longer necessary to view the entire video or listen to the entire audio associated with the transcribed text to find relevant content. When the user highlights text in the transcription, the audio and video corresponding to that text is immediately queued up for viewing. This feature also expedites the assembly of the video program, because the user can quickly identify the particular soundbites which are essential to assembling a particular video program.

[0183] In one aspect of the disclosed technology, a video implemented method is provided for assembling an audio/video program from source A/V files. The method includes importing at least one source audio/video file, where the audio/video file comprising an audio track and a video track. The audio track includes audio frames and the video track including video frames synchronized by time code. The audio track further includes spoken speech from one or more speaker’s voices, which are in synchronization with the corresponding video frames. The method includes creating a text transcription of the spoken speech using a speech-to-text engine. During the creation of the text transcription, each word in the audio track is mapped to corresponding video frames. On a monitor screen, the transcription of the audio is displayed as text in a text window, alongside an indication of the corresponding video frames. The present technology maps the text elements to the corresponding video frames in the transcript map, where each word has a start timecode and end timecode. A user interacts through a user interface to select a text segment and moving the selected text segment with the corresponding video segment into a visual timeline on the monitor screen. The text segment and corresponding video segment are displayed together on visual timeline. [0184] The disclosed technology tracks spoken content for multiple speakers, and the content is automatically labeled for each speaker based on the speech characteristics of each speaker. In one aspect, the spoken content is labeled with speakers’ names. In another aspect, the identification label for each speaker is manually applied by the user. Users may assign a speaker identification label to selected text, and it will propagate to all other paragraphs that are determined by the software to be the same speaker.

[0185] In one aspect, the computer implemented method provides a video timeline for displaying the selected video clips arranged in a chosen display sequence. In some implementations of the method for assembling a video program, multiple text segments and corresponding video segments are moved to the visual timeline and displayed in a user- selected playback order on the timeline. In one example, three or more text and video segments may comprise the assembled video program. In another example of the disclosed method, in response to a play command, the selected segments may be played in order of selection as shown the sequence as indicated on the timeline. Alternatively, in response to a user selection, the sequence of playback may be reordered in a second selected order for playback. And in a like manner, in response to user selection, the playback of the selected video segments on the timeline for playback in a third selected order. The reorder command allows the user to drag-and-drop the text and video selections into a different chosen order. A user may skip forwards or backwards, clicking on chosen thumbnails to jump to that point in the playback, 1104, 1504, or 2004.

[0186] In one aspect, the user may authorize remote collaborators to play the video program and comment in real time or provide feedback the user. The collaborators must be authorized by using passwords and other network security measures. In another implementation of the disclosed technology, it may be desirable to eliminate some video content in the situation where the speakers use an appropriate language for unwanted content. By performing a keyword search on the transcribed text, the unwanted content may be located and deleted from the assembled. List of keywords can also be applied throughout the transcribed text to identify all instances of unwanted content. By deleting unwanted text content, the corresponding video segments will also be deleted.

[0187] In another disclosed implementation, video frames are retrieved corresponding to text selections and the retrieved text and video selections are moved to a timeline display for further editing and assembly of the video program. A completely assembled video program may take the form of a rough-cut video, which will be exported to a secondary video editing system for fine-cut processing.

[0188] The disclosed technology may be implemented as a system for assembling an audio/video program. The system includes an A/V storage bin for storing uploaded video files from a user. The video files comprise an audio track and a video track. The audio track includes audio frames, and the video track includes video frames synchronized by time code. The audio track further including spoken speech from one or more speakers, in synchronization with corresponding video frames. A speech-to-text engine is provided for creating a text transcription of the spoken speech on the audio track, wherein each transcribed word is mapped to corresponding video frames. Aa monitor screen displays the text transcription. User-selected text segments and corresponding video segments are shown. A visual timeline displayed on the monitor screen for sequencing user-selected text segments and corresponding video segments into a user-selected playback order on the timeline. [0189] Some disclosed implementations provide for refining the playback order of user selected text segments and corresponding video segments are carried out by a user’s drag- and-drop actions. The system provides for accepting authorized collaborator interaction with the video program, including playback, providing suggestions, and comments. The collaborators changes may be reflected in the timeline in real-time.

[0190] In one implementation, a system is provided for creating and assembling a video program over a network. A host computer is in operable connection with a network interface. The network interface is in operable connection with a network. An application server is in operable communication with the network interface. An application server is configured to host a website application for assembling a video program, the server having a user interface for providing a remote user with web-page access to the host computer. The user interface is in operable communication with an A/V storage bin and video editing resources. The user interface comprises a webpage screen for assembling video program. The user interface comprises a webpage screen configured for uploading a user’s A/V files into the application. The user interface further comprises a webpage screen configured for displaying a text window for transcribed text from the audio track of selected A/V files, where the displayed text words correspond to timecode-synchronized video content. A webpage screen is configured to provide a timeline, wherein a user may select text segments and video segments corresponding to the transcribed text segments. A webpage screen is configured to show the sequence of selected text segments alongside corresponding video segments in a vertical timeline configuration. A sequence of text segments and corresponding video segments are listed on a timeline display in a chosen playback sequence. The sequence may be reordered by user drag-and-drop actions.

[0191] In a further aspect of the disclosed system, a text window is provided for displaying transcribed text from an audio track, and a video window for displaying image frames corresponding to transcribed text, and a timeline for dropping and dragging transcribed text segments onto the timeline in a user-chosen playback sequence. The timeline displays selected test segments, video preview frames, and a video playback window, wherein the again selected text segments are moved by drag-and-drop actions into a user selected sequence, so that the assembled video program may be played in the selected sequence.
