VideoTrackSelection

VideoTrackSelection

is an option that specifies the video tracks of interest.

Details

  • Typical settings include:
  • nonly process n^(th) track, remove other tracks
    {n1,n2,…}process the specified ni tracks, remove others
    Allprocess all tracks
    Automaticautomatically decide what tracks to process

Examples

Basic Examples  (1)

Export a Video object to an Ogg file without any video tracks:

Wolfram Language code: v = Video["ExampleData/bullfinch.mkv"]; Export["file.ogg", v, VideoTrackSelection -> None]

Check the number of exported video tracks:

Wolfram Language code: Import["file.ogg", {"Ogg", "VideoTrackCount"}]

Scope  (2)

Create a Video object with multiple video tracks:

Wolfram Language code: v = VideoCombine[{Video["ExampleData/bullfinch.mkv"], VideoGenerator[RandomImage[]]}]; Information[v, "VideoTracks"]

Create a new video by selecting only a single track:

Wolfram Language code: new = Video[v, VideoTrackSelection -> 1]; Information[new, "VideoTracks"]

Create a new video by selecting multiple tracks:

Wolfram Language code: new = Video[v, VideoTrackSelection -> {2, 1}]; Information[new, "VideoTracks"]

Create a new video by selecting all tracks:

Wolfram Language code: new = Video[v, VideoTrackSelection -> All]; Information[new, "VideoTracks"]

Video objects need to have at least one video track:

Wolfram Language code: Video[v, VideoTrackSelection -> None];

Create a Video object with multiple video tracks:

Wolfram Language code: v = VideoCombine[{Video["ExampleData/bullfinch.mkv"], VideoGenerator[RandomImage[]], Video["ExampleData/Caminandes.mp4"]}]; Information[v, "VideoTracks"]

Select two tracks out of the three present in the original video:

Wolfram Language code: twoTrack = Video[v, VideoTrackSelection -> {3, 1}]; Information[twoTrack, "VideoTracks"]

Select one track from the two-track video. Notice that the selection is done in a relative manner. By selecting the first track, the third track of the original video is actually retrieved:

Wolfram Language code: oneTrack = Video[twoTrack, VideoTrackSelection -> 1]; Information[oneTrack, "VideoTracks"]

The track selection in the new video is limited to two:

Wolfram Language code: Video[twoTrack, VideoTrackSelection -> 3];

Applications  (1)

Create a Video object with multiple video tracks:

Wolfram Language code: v = VideoCombine[{Video["ExampleData/bullfinch.mkv"], VideoGenerator[RandomImage[]], Video["ExampleData/Caminandes.mp4"]}];

All the Video functions will act on the first track of the input:

Wolfram Language code: VideoExtractFrames[v, .6]

To operate on a different track, use the VideoTrackSelection option:

Wolfram Language code: VideoExtractFrames[Video[v, VideoTrackSelection -> 2], .6]
