Enclosing class:
QuickTimeMeta
public static class QuickTimeMeta.Edit extends Object
An Edit define the portions of the media that are to be used to build up a track for a movie. The edits themselves are stored in an edit list table, which consists of time offset and duration values for each segment.

In the absence of an edit list, the presentation of the track starts immediately. An empty edit is used to offset the start time of a track.
