SnippetsVideo[video,n]

returns a summary video based on n snippets from video.

SnippetsVideo[video,timespec]

returns a summary video based on snippets taken at times specified by timespec.

• SnippetsVideo creates a condensed or summarized version of a long video. The summary can allow for faster review or analysis of the whole content, or can be used as a teaser or trailer.
• Possible settings for time specification timespec include:
• n n uniformly spaced timestamps {"Uniform",n} n uniformly spaced timestamps {"Random",n} n randomly chosen timestamps {t₁,t₂,…} explicit timestamps t_i {w₁t₁,w₂t₂,…} computes snippet duration for each timestamp t_i according to the weight w_i
• The times t_i can be any of the following:
• t time given in seconds Quantity[t,"unit"] time given in "unit" compatible with seconds Quantity[t,"Frames"] time given as a number of frames
• Options to control the snippet selection are:
• Options to control properties of the output video are:

Summary of a video:

Compare the original and summary durations:

Create a summary based on a specified number of snippets to extract from the video:

Join samples of the video at 5 uniformly spaced times:

Compare the original and summary durations:

Compare frames from the original and the summary:

Create a summary video based on 5 randomly sampled snippets:

The summary duration may be shorter than the default duration to avoid returning repeated content if the intervals around the randomly spaced times overlap:

Show frames from the summary video:

By default, for longer videos a 30-second summary is created:

Specify a different duration:

For shorter videos, a shorter summary is used:

Specify an explicit duration:
