SC (4).mp4

Is there any way Power BI/Powershell can export .mp4 file-related data from OneDrive for business and SharePoint Online so as to look at the metadata of the Teams Meeting Recording .mp4 files which can be differentiated from non Teams Meeting recording files? Thanks in advance!

SC (4).mp4

1.Teams meeting recordings' [Sharing] column is automatically displayed as Shared (share with people who joined in this meeting), and (non Teams meeting recordings) .mp4 files are Private by default unless you specify whom to share to.

  • The detailed specification how screenshot options work:First of all, after all the --screenshotand --screenshot-range options are processed,view3dscene exits. So they work in "batch mode".The --screenshot TIME FILE-NAME simply savesthe screenshot at time TIME to an image file FILE-NAME.Image format is guessed from FILE-NAME extension,see castle-view-image for detailed list of image formats that we can handle.In short, we handle many popular image formats, like PNG and JPG,and these are what usually you want to use.The --screenshot-range TIME-BEGIN TIME-STEP FRAMES-COUNT FILE-NAMEoption takes FRAMES-COUNT screenshots. The first screenshotis at time TIME-BEGIN, second screenshot is atTIME-BEGIN + TIME-STEP, next one is atTIME-BEGIN + 2 * TIME-STEP... you get the idea.The FILE-NAME is eitherA movie filename. This must have a recognized movie MIME type(for local files, MIME type is just recognized from extension),this includes:video/x-msvideo (.avi)video/mpeg (.mpeg, .mpg, .mpe)video/ogg (.ogv)video/quicktime (.mov)video/x-flv (.flv)application/x-shockwave-flash (.swf, .swfl)video/mp4 (.mp4)Please report if we miss some MIME type (and file extension)above, it's trivially easy to add all formats supported by ffmpeg.Availability of all these video formats may depend on installed ffmpegcodecs.ffmpegmust be installed and available on $PATH for this to work.FILE-NAME may also be a pattern to generatenames of images to save, like @counter(4).png.Details about using filename patterns are below (although youcan probably already guess how it works :) ).All filenames for both screenshot options may specify a patterninstead of an actual filename. A pattern is simply a filenamewith macro @counter() inside, when capturing @counter(4)will be replaced by the current screenshot number (padded with zeros to 4 digits).For capturing a series of imagesby --screenshot-range it's even required to specifya pattern with @counter() (since capturinga number of images to a single image file has no point...). Butit's also allowed in all other cases, even a movie filenamemay also be a pattern with @counter() sequence,in case you want to use multiple --screenshot-rangeoptions to get multiple auto-named movies.The precise description how @counter() works:All --screenshotand --screenshot-range options are processed in order.When a filename with pattern @counter() is found, we replace all@counter() occurrences in this filename with current counter valueand increment the counter. For --screenshot-range withan image pattern, we do this for every single frame.The counter starts at 1.The parameter of @counter()is the padding.For example, @counter(1) results in names like1, 2, ..., 9, 10... while @counter(4)results in names like 0001, 0002, ..., 0009, 0010, ...Add --screenshot-transparent option to have a transparent image,with transparent pixels in place where background color would be visible.Examples:Simply get a single screenshot at given time:view3dscene my_model.wrl --screenshot 0 output.png

  • Simply get a movie of 2 seconds of animation.To calculate the numbers, note that we generate a movie with25 frames per second:view3dscene my_model.castle-anim-frames --screenshot-range 0 0.04 50 output.aviTo get this as a sequence of images, just use [email protected](4).pnginstead of output.avi.

  • Example of more complicated use:view3dscene my_model.castle-anim-frames \ --screenshot-range 0 0.04 50 [email protected](1).avi \ --screenshot-range 10 0.04 50 [email protected](1).aviThis generates two files: output1.avi with 2 second animationfrom 0.0 to 2.0 time, and output2.avi with 2 second animationfrom 10.0 to 12.0 time.


Published Scenes are able to be shared. This can be done by clicking the "Share" button under the video to copy the URL for the page to your clipboard. They are also able to be exported as .mp4 files and viewed locally on a device. This is done by clicking the "Export MP4" button, where the user can pick between 2 resolutions to export in. 960 x 640 is the standard resolution for an video. 1280 x 854 is more suited for YouTube uploads. videos are also able to be recorded using the Recorder made by Sylveon. This is a tool suited towards recording longer scenes. Users who have created the video they are watching also have access to an "Edit Objection" button. This allows them to make changes to the frames of the video, while keeping it under the same URL.

  • Important Dates:Please check the TRECVID 2021 schedule for important dates.Run submission format:Participants will submit results against BBC Eastenders dataset in each run for all and only the 5 main characters chosen for the summarization task that year, within the time frame specified by NIST.

  • Each team is asked to submit 4 prioritized runs per task submission.

  • Submissions will comprise of the final automatically generated video summary for each topic, in .mp4 format, in addition to the xml container, as below, fully decribing the run submissions.

  • Video summaries must be named ___.mp4

  • For example, team SiriusCyberCo, submitting their secondrun, on the main task of unknown questions, for topic Heather, must name their submission: SiriusCyberCo_1_2_Heather.mp4SiriusCyberCo, submitting their fourthrun, on the subtask of known questions, for topic Heather, must name their submission: SiriusCyberCo_2_4_Heather.mp4

  • Please note: Only submissions which are valid when checked against the supplied DTDs will be accepted. You must check your submissionbefore submitting it. NIST reserves the right to reject any submission which does not parse correctly against the provided DTD(s). Variouscheckers exist, e.g., Xerces-J: java sax.Counter -v YourSubmision.xml.

  • Here for download (right click and choose "display page source" to see the entire file) is the DTD for summarization results of one run and a small example of what a site would send to NIST for evaluation.Please check your submission to see that it is well-formed

  • Please submit each run information in a separate file, named to make clear which team it is from. EACH file you submit should begin, as in the examplesubmission, with the DOCTYPE statement and a videoSummarizationResults element even if only one run is included:

  • Submissions will be transmitted to NIST using this password-protected webpageVSUM java Run Checker can be found at VSUM Active Directory. Please check files before submission.Queries:The following table specifies this years query characters, the time frame of the series (Start Shot # and End Shot #), links to images of the query characters, and the maximum length and number of shots for each run.

  • Important: All participating teams should submit 4 runs for each query, using the specified maximum number of shots for each run.

  • Evaluation:In 2021, all submitted video summaries will be evaluated by assessors at Dublin City University.

  • A set of questions for each summary will be diseminated to assessors, but not to participants, for evaluation of summary content.

  • Summaries are also evaluated according to tempo, contextuality, and redundancy of generated video summaries:

  • Estimate the Tempo and Rhythm of this video summary, on a Likert scale of 1 - 7. High is best. Tempo/Rhythm Defined as: How well do the video shots flow together? Do shots cut mid-sentence (indicating poor tempo/rhythm)? Do they flow together nicely so it wouldn't be obvious that this is an automatically generated summary (high tempo/rhythm)? Estimate the Contextuality provided by this video summary, on a Likert scale of 1 - 7. High is best. Contextuality Defined as: Does the content provide the circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed? (High is best)

  • Estimate the level of Redundancy in this video summary, on a Likert scale of 1 - 7. Low is best. Redundancy Defined as: Does the video contain content considered to be unnecessary or superfluous? (Low is best)

  • Measures:Scoring measures for summaries will be calculated from the content based questions and also from the tempo, contextuality, and redundancy based Likert scale estimates described above.

  • Important notesThe BBC requires all VSUM task participants to fill, sign and submit a renewal data License agreement in order to use the Eastenders data. That means that even if a past participant has a copy of the data, the team must submit a renewal License form before any submission runs can be accepted and evaluated.

  • No human preknowledge to the closed world of the Eastenders dataset is allowed to be used to filter content. Any filteration methods should all be automatic without fine tuning based on the Eastenders dataset human knowledge.

  • The usage of the included xml transcripts' files are limited to only the transcripted text and not to any other metadata (or xml) attributes (e.g. color of text, etc).

  • Open Issues:BBC Eastenders data License is now available from the BBC [RESOLVED]
