QuickTime Movie Sound Settings
Click Settings in the Sound area of the Movie Settings dialog to choose an audio format,
number of channels, sample rate, and additional settings. Depending on the format you
choose from the Format pop-up menu, additional settings may be available.
Important: If there is no audio in your clip or sequence, deselect the Sound checkbox
in the Movie Settings dialog. Otherwise, blank audio tracks are created in your
QuickTime movie file, which require additional space.
 Format: To reduce file size and download bandwidth, choose a codec to compress
the audio tracks. If you’re outputting full-resolution audio, choose Linear PCM.
 Channels: Select Mono, Stereo (L R), or 2 Discrete Channels. If you’re delivering
material for the Internet, you may want to choose Mono because it cuts your audio
file size in half. Some formats support additional channel configurations.
