Inside Macintosh: QuickTime Reference

The export command

The export command can be used in several different ways. For example:

to save a movie to another file in a different format.
to "mix down," i.e., to combine multiple audio and video tracks into a single audio and video track, respectively.
to hint a movie for streaming playback.

Also, for example, if you need to stream a movie, you can automate the process of exporting a hinted movie using the export command.
