 Depth: Choose the bit depth used for each sample.
 8-bit: This bit depth is useful for highly compressed movies created for the web.
Unless you have a specific need for 8-bit audio, you should avoid this option
because the quality is fairly low.
 16-bit: This is the bit depth of DV, DVCAM, and DVCPRO, as well as of music CDs. If
all of your original audio media is 16-bit, and you aren’t routing multiple audio
tracks to the same audio output, choose this option.
 24-bit: A high-resolution bit depth compatible with many third-party video and
audio interfaces. Choose this option to preserve the highest possible quality when
exporting your files, especially when some of your audio files are 24-bit, or when
you are mixing multiple audio channels together by routing them to the same
output channel.
 Configuration: This pop-up menu works in combination with the Downmix control in
the Audio mixer to determine how the Export QuickTime Movie command groups
your sequence audio outputs during export.
 Default: If the Downmix control is enabled in the Audio Mixer, a QuickTime movie
with stereo audio is created. If the Downmix control is disabled, a QuickTime movie
is created with multiple audio tracks corresponding to the audio output channels
of your sequence.
You can override the status of the Downmix control by using the following two
controls instead:
 Channel Grouped: Exports multiple stereo or mono tracks based on your
sequence’s audio output groupings.
 Stereo Mixed: Outputs a single stereo file based on your sequence’s stereo
downmix settings.
