with QuickTime Pro
If you want more control over how QuickTime creates
a file, use the Export feature of QuickTime Pro.
With QuickTime Pro, you can export a movie to a number of different file formats, such
as QuickTime movie (MOV), MPEG-4, 3GPP, 3GPP2, AVI, and DV. In addition, you can
export an audio track to several different audio formats, export the individual frames of
a movie as separate image files, or export a text track to a text file.
To see the list of file formats available for a movie open in QuickTime Player, choose
File > Export and browse the list of file format choices in the Export pop-up menu.
