The movie class

The movie class is the central class in the QuickTime Player Suite. Most of the QuickTime Player suite events target a movie, including play, stop, save, export, and find. Tracks, files, internet locations, windows, and annotations are all parts of a movie.

This class provides access to many useful properties of a movie, such as name, current time, duration, volume, selection, and dimensions. Many of these properties can be set, such as current time, selection, volume, and dimension.
