Setting and Naming Chapter Points
Chapter Points define places in the movie you would like the viewer to be able to jump to,
or places you would like to invoke a URL. Additionally, there is always a Chapter Point at the
beginning of a movie. They are typically set at scene changes or where an event occurs that
the viewer may want to go to directly.
While Chapter Points allow the viewer to skip to a particular place in the movie, they do not
affect when playback stops. In other words, when you start playing from a Chapter Point,
the movie plays to its end (or until the viewer stops it), no matter how many other Chapter
Points exist.
Chapter Points must fall on MPEG I-Frames; typical MPEG encoded video has 2 or 3 of these
per second, depending on the GOP setting. See the Video Assets topic for more information
on I-Frames and GOPs. In addition, there is a limit of 99 Chapter Points per movie. A title
can contain multiple movies, each with its own 99-point limit.
