Config Pop-Up Menu
Both the Export Audio to AIFF(s) command and the Export QuickTime Movie command
use a Config pop-up menu to determine whether sequence audio output busses should
be exported individually or as a stereo downmix. However, each command has a different
Config pop-up menu in different locations:
• File > Export > QuickTime Movie: The Config pop-up menu is in the Audio Settings area
of the General tab of the Sequence Settings window. There are three options:
• Stereo Downmix: This option exports a stereo mix to a single stereo QuickTime audio
track and overrides the Downmix button in the Audio Mixer. For more information,
see
“Downmixing Multiple Audio Channels to a Stereo Mix.”
• Channel Grouped: Based on your sequence’s audio output groupings, multiple stereo
and mono output busses are exported to corresponding stereo and mono QuickTime
tracks. For more information, see
“Assigning Tracks in the Timeline to Audio Outputs.”
• Discrete Channels: This option exports channels in the same way as the Channel
Grouped option, but each channel in the QuickTime movie audio track is labeled as
a discrete channel, numbered according to the audio output bus that the channel
is assigned in your sequence. Use this option when you want to preserve your
sequence’s original audio output assignments in your exported QuickTime file. Note
that if you reimport a discrete-channel QuickTime file into Final Cut Pro, the resulting
clip appears to have all mono channels.
• File > Export > Audio to AIFF(s): The Config pop-up menu appears in the Save dialog
after you choose this command. There are two options:
• Stereo Downmix: This option exports a stereo mix to a single stereo AIFF audio file.
For more information, see the next section, “Downmixing Multiple Audio Channels
to a Stereo Mix.”
• Channel Grouped: Based on your sequence’s audio output groupings, multiple stereo
and mono output busses are exported to corresponding stereo and mono AIFF files.
For more information, see
“Defining Output Busses by Grouping.”
For more information about exporting QuickTime movies, see “Exporting QuickTime
Movies.” For more information about exporting AIFF files, see “Exporting Audio Output
Groups to AIFF Files.”
Downmixing Multiple Audio Channels to a Stereo Mix
Even when you use multiple audio channels during editing and mixing, you may need
to create a stereo mix. Downmixing combines all audio output channels into a single
stereo output. You may want to downmix when:
• Playing back a sequence with multiple output channels on a system with only two
speakers
