FIGS. 6-17 are illustrations of implementations of user interfaces for a logger, such as for presenting, selecting, conforming, matching, and logging audio and video elements (e.g., frames, tracks, segments, clips, waveforms, filmstrips, events) . DETAILED DESCRIPTION

Certain implementations as disclosed herein provide for displaying- audio and video^" from data files and attaching metadata to the files. After reading this description it will become apparent how to implement the invention in

various alternative implementations and alternative applications. However, although various implementations of the present invention will be described herein, it is understood that these implementations are presented by way of example only, and not limitation. As such, this detailed description of various alternative implementations should not be construed to limit the scope or breadth of the present invention .

In one implementation, a software tool referred to as a logger is used to log events in a media file, such as a movie. The logger tool provides a user interface allowing a user to view the video in multiple ways and add information to the file to track and log events in the file including the locations of bars and tone, slates, content, logos,

commercial blacks, quality control issues, subtitles, and captions. The logger tool allows the user to capture and validate key events within the media file required to enable downstream automated post production processes and workflows.

In one implementation, the user interface provides access to the media file and also provides an interface to create, track, and edit events for that media file. The user interface allows automatic presentation and association of events with the media file at their proper location, which can improve throughput and quality of the data. Events can be generated manually by the user within the logger tool and also generated by importing lists or tables of events created externally. The events can then be associated with the media file within the logger tool. For example, a user can import a quality control report into the logger tool and the logger tool is used to create events for the file matching the quality control entries. In another implementation, the logger tool can also present information and views on frame matching and/or differentiation based on imported matched and/or differentiated data.

FIG. 1 shows a screen shot of a queue page 100 of a logger in accordance with one implementation of the present invention. Queues shown on the queue page 100 are designed to track the progress of media files through each status of a logging process.

In the illustrated implementation of FIG. 1, the queue page 100 of the logger includes following items/fields:

status bar 110, item counter 112, 'sort by drop-down' 114, search field 116, 'expand/collapse all' 118, title 120, identifiers 130, expand 122, thumbnail 124, collapse 126, file specs 128, 'add movie' field 132, and logout. The status bar 110 is clicked to display the files in the selected status, which includes All, Loading, Ready for Logging, User working, Ready for Review, Completed, and Rejected. The item counter 112 displays the number of files showing for the chosen status. The 'sort by drop-down' item 114 is clicked to select an identifier (e.g., Title, Status, Task Id, Added date, Feature, User assigned, and Kit Id) in which the files will be arranged and viewed. The search field 116 displays the files that meet the entered keyword criteria. The 'expand/collapse all' item 118 is clicked to expand or collapse additional file information (i.e., file specs) for all files in the current status. The title 120 includes a file name that is clicked to proceed to a video page of the logger. The identifiers field 130 shows file specific identifying information. The expand icon 122 is clicked to display additional file information. The

thumbnail 124 shows a single frame selected to visually represent the file. The collapse icon 126 is clicked to hide additional file information. The file specs 128 show additional technical file information. The 'add movie' field 132 is used to insert a selected file not currently in the logger tool into a loading status.

FIG. 2 shows a snapshot of a video page 200 of the logger reached by clicking a title including a media file name (e.g., 120 in FIG. 1) . In one implementation, the video page 200 of the logger includes sections, controls, and commands that are used to view, verify, and capture events. For example, the video page 200 of the logger

provides/displays following: an adjustable filmstrip of thumbnails for all or part of a video file; audio waveforms for the video; the video with timing information (e.g., time code, tape time code, frame number) events associated with the video and their location in the file (e.g., by time code) ; interfaces to display and playback video and audio waveforms; interfaces to create, edit, and delete events for the video file; interfaces to create re-usable clips from a video file (e.g., creating new logos); interfaces for editing, importing, and copying events or groups of events within a file or across files; interfaces to a user through a web browser.

In the illustrated implementation of FIG. 2, the video page 200 includes following sections, controls, and commands: page selector 210, event overview 212, master strip 214, looking glass 216, event strip 218, event indicator 220, anchor 222, audio waveform 224, audio magnification 226, standard timecode 228, tape timecode 230, frame number 232, player controls 234, magnification slider 236, volume slider 238, player pane 242, and stack view 240. The page selector 210 is used to choose which page to view (e.g., Queue, Video, or Audio) . The event overview 212 represents sections of the file containing events. In one case, known events and unknown events are represented by different colors.

The master strip 214 represents the entire file timeline from start to end. The looking glass 216 is located in the. master strip 214 and magnifies the surrounded section of the file in the event strip 218. The default position of the looking glass 216 upon opening a new file contains the entire file. The event strip 218 is a magnified section located inside the looking glass 216 on the master strip 214 that can split the file into events. The event indicator 220 is a stroke that outlines each individual event. For example, a first thumbnail within the event indicator 220 is the first frame of the event, and a last thumbnail within the event indicator 220 is the last frame of the event. The anchor 222 is represented by a vertical line that crosses the event strip 218 and audio waveform which represents the location in the file. This file location will display in the player pane 242. The player controls 234 are buttons that control basic playback tasks such as playing, pausing, fast forwarding, and rewinding. The magnification slider 236 adjusts the size of the looking glass 216 which can increase or decrease the amount of the master strip 214 that is displayed in the event strip 218. The player pane 242 displays the frame located to the right side of the anchor 222. The stack view section 240 is the action center of the logger video page 200.

In one implementation, the video page 200 of the logger can be navigated using the sections, controls, and commands described above. For example, the master strip 214 can be navigated by clicking and dragging the looking glass 216 to the right or left to view different sections of the file in the event strip 218. The size of the looking glass 216 can be adjusted by moving the magnification slider 236 toward minutes to increase the size of the looking glass 216 and toward frames to decrease the size of the looking glass 216. In another example, the event strip 218 can be navigated by clicking and dragging the anchor 222 to the right or left along the event strip 218. The event strip 218 can be dragged to the right or left while the anchor 222 remains in the same location. Dragging the event strip 218 also moves the looking glass 216 in the master strip 214. When the desired event on the event strip 218 is clicked, the event strip 218 will move to place the anchor 222 before the first frame of the selected event. Either the Enter key can be pressed or the event on the event strip 218 can be clicked to also expand the event in the center of the strip 218. Up or down arrow key can be used to move to the next or previous event. In yet another example, when an event in the stack view 240 is selected, the event strip 218 will move to place the anchor 222 before the first frame of the selected event, and expand the event in the center of the event strip 218.

FIG. 3A shows a snapshot of a stack view 300 in the video page 200 of the logger in accordance with one

implementation of the present invention. ^'The stack view 300 shows the tasks being completed as well as filter tools and other information. In the illustrated implementation of FIG. 3A, the stack view pane 300 includes track information 310 (including a track drop down button 312 and an add track button 314), tabs 330 for showing filters 332 (see FIG. 3B) , video information 334 (see FIG. 3C) , and logos 336 (see FIG. 3D), and event row 320. As described above, known events and unknown events can be represented by different colors 322.

The stack view pane 300 further includes 'All Notes Expander' 316 and 'Notes Expander' 318. The track information 310 section provides options to: import quality control report, captions, subtitles, or script alignment; copy from a selected title; or create an unknown default event that represent the entire file.

FIG. 3B shows a screenshot of a list of filters 332 displayed when the filter tab is selected. A selection of one or more filter from the list of filters allows viewing of the events contained in an individual track by category.

Thus, the filter can be selected to show in the track only the events in that filter category. More than one filter can be turned on at one time to allow viewing of the events in the selected filter categories by pressing multiple filter buttons.

FIG. 3C shows video information 334 displayed when the video info tab selected in the tabs area 330. The video information 334 provides information such as frame rate, language, and other pertinent video information.

FIG. 3D shows logos information 336 displayed when Logos is selected in the tabs area 330. To view logos in the logos window of the stack view 300, click the logos button under the track name. To search logos, click to place the cursor in the search field with the logo window open. To create a new logo, execute the following steps: create an event that represents the logo from start to end; click on the 'edit mode' icon in the stack view for the event that contains the logo; choose 'Logo' in the event category menu and the corresponding logo type (e.g., Logo, Production Company Logo, Distribution Logo, or Production Logo) ; place the anchor on the frame that most accurately represents the logo in the event strip; click the 'OK' button or double-click the correct event type in the event category menu; type in the desired logo name in the search field when the logo window appears over the stack view; click the 'Create New' button; and click the 'submit' button to assign the newly created logo to the event when the new logo appears in the stack view.

Returning to FIG. 3A, each event row 320 will display the event type it has been assigned, the event description, duration, as well as start and end. The measurement of the duration and start and end information^' will display based on the highlighted measurement field. Each event type is represented by a different color 322 in the 'event type' column in the stack view 300. Table 1 shown below broadly defines the available event types.

Textless Start Textless End Non-texted portions of the program located at the end of the file. Some titles do not have textless material available.

Table 1

Each track includes at least one event that represents the entire file from beginning to end, or many imported or copied events that combined include the entire file. Each new event is a portion of an existing event. Thus, to create a new event, place the anchor on or directly in front of the first frame of the event to be created in the event strip. This will display the first frame of the event in the player pane. Select to split the current event into two events. The frame to the right of the anchor now represents the first frame of the new event and the frame to the left of the anchor represents the last frame of the previous event. The event will automatically be categorized as Unknown.

FIG. 4A illustrates a representation of a computer system 400 and a user 402. The user 402 uses the computer system 400 to log events in a media file, such as a movie. The computer system 400 stores and executes a logger 490.

FIG. 4B is a functional block diagram illustrating the computer system 400 hosting the logger 490. The controller 410 is a programmable processor and controls the operation of the computer system 400 and its components. The controller 410 loads instructions (e.g., in the form of a computer program) from the memory 420 or an embedded controller memory (not shown) and executes these instructions to control the system. In its execution, the controller 410 provides the logger 490 as a software system, such as to enable logging of events in a media file. Alternatively, this service can be implemented as separate hardware components in the controller 410 or the computer system 400.

Memory 420 stores data temporarily for use by the other components of the computer system 400. In one

implementation, memory 420 is implemented as RAM. In one implementation, memory 420 also includes long-term or permanent memory, such as flash memory and/or ROM.

Storage 430 stores data temporarily or long term for use by other components of the computer system 400, such as for storing data used by the logger 490. In one implementation, storage 430 is a hard disk drive.

The media device 440 receives removable media and reads and/or writes data to the inserted media. In one

implementation, for example, the media device 440 is an optical disc drive. ^{' ~} -

The user interface 450 includes components for accepting user input from the user of the computer system 400 and presenting information to the user. In one implementation, the user interface 450 includes a keyboard, a mouse, audio speakers, and a display. The controller 410 uses input from the user to adjust the operation of the computer system 400.

The I/O interface 460 includes one or more I/O ports to connect to corresponding I/O devices, such as external storage or supplemental devices (e.g., a printer or a PDA) . In one implementation, the ports of the I/O interface 460 include ports such as: USB ports, PCMCIA ports, serial ports, and/or parallel ports. In another implementation, the I/O interface 460 includes a wireless interface for communication with external devices wirelessly.

The network interface 470 includes a wired and/or wireless network connection, such as an RJ-45 or "Wi-Fi" interface (including, but not limited to 802.11) supporting an Ethernet connection.

The computer system 400 includes additional hardware and software typical of computer systems (e.g., power, cooling, operating system) , though these components are not

specifically shown in FIG. 4B for simplicity. In other implementations, different configurations of the computer system can be used (e.g., different bus or storage

configurations or a multi-processor configuration) .

FIG. 5 is a flowchart illustrating a method 500 of logging events in a media file in accordance with one implementation of the present invention. In the illustrated implementation, the method comprises configuring a logger tool, at box 510, to allow a user to view media in multiple ways (box 512). The user also captures and validates key events within the media file, at box 514. Events in the media file are tracked and logged, at box 520, by adding information to the media file, at box 522, including

locations of bars and tone, slates, content, logos,

commercial blacks, quality control issues, subtitles, and captions .

Various implementations can include, but are not limited to, one or more of the following items:

• Providing an adjustable filmstrip of thumbnails for all or part of a video file

• Displaying audio waveforms for the video

• Displaying the video with timing information (e.g., time code, tape time code, frame number)

• Displaying events associated with the video and their location in the file (e.g., by time code)

• Providing a UI (user interface) to control the display and playback of video and audio waveforms

• Providing a UI to create, edit, and delete events for the video file

• Providing a UI to create re-usable clips from a video file (e.g., creating new logos) • Providing a UI for editing, importing, and copying events or groups of events within a file or across files

• Automatically creating selected events by analyzing a file (e.g., commercial blacks or slates)

· Providing a UI and operations for frame matching,

allowing a user to match frames within or across files

• Providing a UI and operations for audio conforms,

finding similarities and differences in audio waveforms

• Providing a UI and operations for audio component

creation

• Providing a UI and operations for AVID export - ability to export the frame match data to an Avid AAF (Advanced Authoring Format) / EDL (Edit Decision List) or

Quicktime reference movie

· Providing a UI and operations for on screen annotation in the video UI (i.e. hand draw on the frame)

• Providing a UI and operations for QC report generation

• Providing a UI and operations for auto text in picture detection

· Providing a UI and operations for speech to text

processing and results display with editing capability

• Providing a UI and operations for manual transcription tools

• Providing the interface to a user through a web browser • Providing the audio and video through the logger using streaming from a server, instead of or in addition to using download and local copies of files

In one implementation, the logger includes components to support a set of features that allow users to match frames from the same, or different movie files. This frame matching feature's underlying algorithm centers around a basic concept known as the law of absolute difference, and compares positive and negative frames to determine relevance of the match and then returns the results based on a defined threshold. This functionality provides users with the ability to create textless masters and foreign texted masters by matching the inserts to the original program. In one example, a first file contains the original movie and a second file contains inserts, groups of frames to replace corresponding groups of frames in the original (e.g., frames with localized text for a particular language) . Using frame matching, the user can identify the original frames that match the insert frames and then indicate which frames in the original movie file to replace with which frames from the insert file

(manually and/or automatically) . The logger can then output a new version using the original frames with selected frames replaced with the selected insert frames. Alternatively, the logger can create a file (e.g., a table of references) that guides playback between the original file and the insert file. A user can then create another file for different language using a different insert file.

The UI provides the users with the ability to see the results play side by side in a player window and includes default storyboard mode as well as a view in "precise" mode where users can fix and adjust if there are insert/original frame mismatches of inconsistencies. In addition, users can preview their versions "real-time" and toggle between

languages. This allows for a preview of the foreign language master "virtual edit" before it's rendered into an actual file. During playback in the preview area, inserts will be added to the movie on the fly by keying off of the EDL

created during the matching process. Users can also select audio and text elements to render as part of the preview.

In one implementation, the logger includes components to support a set of features for audio conforming and audio analysis that allow users to compare wave forms to each other and find similarities and/or differences. This technology is part of the logger feature set and is part of the audio UI.

In another implementation, the audio analysis and/or audio UI can be implemented in a separate program or component. The following figures illustrate aspects of the audio UI. Users can select a "gold" reference channel - this is a channel that all of the other channels will be conformed to (e.g., offset or shifted to synchronize) . Once the results come back the audio channels will lock into place and offsets will be recorded. Users then validate that the conform results are accurate and lock the component. As new components are ingested for that title and this auto conform process runs, only unlocked components will be analyzed.

In another implementation, the logger includes

components to support a set of features for creating audio components. For example, a user can combine multi-part audio components to one part, e.g., 6 reels of audio rendered into 1 longplay file. In one implementation, this audio component creation is also part of the logger audio UI . The audio UI provides the users a feature that allows users to ingest multi-part audio components, conform them and then render a new component. The resulting components could then be used in a distribution system or other post-production workflows. One implementation of audio component creation also provides these features: sample rate conversion, sync pop removal, basic envelopes and real-time preview".

The above description of the disclosed implementations is provided to enable any person skilled in the art to make or use the invention. Various modifications to these implementations will be readily apparent to those skilled in the art, and the generic principles described herein can be applied to other implementations without departing from the spirit or scope of the invention. Accordingly, additional implementations and variations are also within the scope of the invention. For example, the examples focus on displaying and logging for movies, but a logger can be specialized for other video, such as television shows, internet video, or user generated content, or for audio, such as radio or podcasts, or other content, such as games or text, or combinations thereof (e.g., matching and conforming video, audio, and text, such as for screenplay matching and

tracking) . All features of each example are not necessarily required in a particular logger implementation. Further, it is to be understood that the description and drawings presented herein are representative of the subject matter which is broadly contemplated by the present invention. It is further understood that the scope of the present invention fully encompasses other implementations that may become obvious to those skilled in the art and that the scope of the present invention is accordingly limited by nothing other than the appended claims.
