Add multi-channel audio from a QuickTime movie
You can import multi-channel audio from QuickTime files as a single stereo track or as
individual tracks.
1. In Motion, choose File > Import (or press Command-I).
2. In the dialog, select a QuickTime movie file that contains stereo or multi-channel
audio tracks.
3. Click the Audio pop-up menu at the bottom of the Import Files dialog, then choose an
import option:
• Mix to Stereo: Imports the movie file as a single stereo track.
• Import All Tracks: Imports the movie file with a separate audio track for each channel.
4. Click Import.
If you chose Mix To Stereo, the Audio list displays a single audio track
If you chose Import all Tracks, the Audio list displays an individual audio track for each
channel in the file. The following image shows the Audio list after importing a stereo
QuickTime movie file using the Import All Tracks option, with the resulting left and
right tracks.
When you export a multichannel audio file from Motion, you can export all channels or mix
them down into a single track. See Select audio output channels in Motion.
Play audio files in Motion
Play audio in your project
• In Motion, click the Play button in the timing toolbar above the Timeline.
All audio tracks in the project that are turned on and not muted play back.
Scrub an audio track
You can scrub an audio track to hear the audio in your project as you drag the playhead.
• In Motion, press and hold the Option key while dragging the playhead in the Timeline,
mini-Timeline, or Audio Timeline.
Pausing while dragging (but continuing to press and hold the Option key and mouse
button) loops the five frames adjacent to the current frame.
Audio looping while scrubbing is turned on by default. You can turn off looping by choosing
Motion > Preferences, clicking the Time icon, then deselecting the “Loop audio while
scrubbing” checkbox.
