4 If you want the workflow to automatically detect changes in the input movie and use
this information to assign chapters in the generated podcast, select Automatic Chapter
Generation.
In the case of a screen recording, the workflow inserts a chapter marker in the video
when it detects a slide transition or when no changes occur in the video at a certain
moment. This is useful when doing a screen recording or for any video that includes
presentations.
The tool used by the workflow to add chapter markers detects stability in a movie by
comparing frames and after the tool finds a stable sequence, it considers it a chapter.
Then, when the sequence changes to another sequence, the tool consider that change
a transition.
Chapter markers are recommended for screen recordings, but not for video and audio
recordings. However, there are instances when adding these markers is useful, such
as when the source video is for a screen recording captured from the VGA or DVI
stream of a computer screen. Screen recording using Podcast Capture works only on a
computer running Mac OS X v10.5 or later.
