✖

extracts a frame at time t from video.

✖
VideoExtractFrames[video,tspec]

extracts video frames at time specification tspec.

Details and Options

  • VideoExtractFrames can be used for extracting frames from a video. Frames can be used as thumbnails or in thumbnail grids, or can be used to inspect a video at desired times.
  • Possible settings for time specification tspec include:
  • ta single frame at time t
    {t1,t2,…}a list of frames at times t1, t2, …
    Interval[{t1,t2}]all frames from time t1 to time t2
    Allall frames
  • The times ti can be any of the following:
  • ttime given in seconds
    Quantity[t,"unit"]time given in "unit" compatible with seconds
    Quantity[t,"Frames"]time given as a number of frames
  • The following options can be specified:
  • MaxItems Infinitymaximum number of frames to extract
