1118 Chapter 13 Working with Audio
You can add keyframes for volume and pan to an audio track and trim an audio track in
the Audio Editor or in the Keyframe Editor. You can also trim an audio track in the
Timeline.
You can export audio with video, or export audio alone, in a variety of formats. See
“
Exporting Audio ” on page 1145 for a list of the audio export formats Motion supports.
If you have Soundtrack Pro installed, an audio file that exists in a Motion project can be
opened and modified in Soundtrack Pro. The modified file is automatically updated in
Motion. For more information, see “
Using Soundtrack Pro with Motion ” on page 1144.
Audio Files in Motion Projects
You can add different kinds of audio files to a Motion project. In addition, Motion lets
you preview files before adding them to your project and lets you view the audio files
in a project in several ways.
Import File Formats
Motion supports audio in a variety of common file formats, sample rates, and bit
depths. Supported import file formats include:
 AIFF
 WAV
 MP3
 AAC (except rights-protected AAC files)
 QuickTime Audio (.mov)
Note: Multitrack QuickTime movie files and multichannel audio files are also
supported.
You can import audio files with sample rates up to 192 kHz and with bit depths up to
32 bits. Mono and stereo files are supported.
Note: Because MP3 and AAC are compressed file formats, playback quality may not be
as high as with uncompressed formats such as AIFF.
