Working with Audio
When you add any media file to Motion, an audio track appears that can be used
independently of the video file. When the file is unlinked from its source, a track can be
individually enabled, disabled, or deleted. Deleting a source QuickTime movie file from
the Media tab, however, deletes all audio and video that originated from that file.
Important:
Because Soundtrack Pro also supports multichannel and multitrack audio
files, you can open a multichannel file in Soundtrack Pro from Motion. For more
information on modifying audio tracks in Soundtrack Pro, see “
Note: When you export a multichannel audio file from Motion, you may choose
whether to export all channels or mix them down into a single track.
To import a multitrack QuickTime movie file using the drop menu:
1
Drag the file from the File Browser or the Finder to the Canvas, holding down the
mouse button until a drop menu appears.
2
Do one of the following:
 To import the movie with a single audio track, choose Mix To Stereo, then release the
mouse button.
 To import the movie file with a single audio track for each track, choose Import All
Tracks, then release the mouse button.
When you choose Mix To Stereo, the file appears in the Audio tab as a single audio
track and the video appears in the Canvas (and Layers tab). The link icon in the Lock
column of the Audio tab indicates that the audio object has a corresponding video
element.
Note: When a multitrack QuickTime file is imported without using the drop menu,
Mix To Stereo is the default import method.
