Select output channels
If you’re working with more than one audio track, you can adjust which tracks are assigned to which output channels, or you can create your own multichannel file from mono tracks.
Important: To export multichannel audio from Motion, you must first set the Master track output from Stereo to 5.1 Surround. You can then export up to six channels of mono audio. For more information, see Export audio only.
Set or change output channels
Do either of the following:
To set the channel for a specific audio track: In the Audio list, click the output channel pop-up menu for the audio track.
To set the Master track output: In the Audio list, click the output channel pop-up menu in the Master track area, then choose 5.1 Surround or Stereo.
