Change the audio track’s duration and playback speed in the Audio Timeline
Motion lets you change the timing of audio tracks in the Audio Timeline.
Important: To affect all channels of a multichannel audio file, select all tracks in the Audio
list before making adjustments in the Audio Timeline.
1. In the Audio Timeline in Motion, position the pointer over the end of an audio track’s the
green bar.
2. Do any of the following:
• Shorten track duration and increase playback speed: Press and hold the Option key,
and drag the end of the green bar to the left.
• Lengthen track duration and slow playback speed: Press and hold the Option key,
and drag the end of the green bar to the right.
As you drag, the retiming pointer appears, and a tooltip displays the track’s duration
and speed.
Loop an audio track
Another way to extend an audio track’s duration is to loop it. You can easily loop a track by
adjusting it in the Audio Timeline. When a looped audio track reaches its last frame, the
audio starts playing from its first frame.
1. In the Audio Timeline in Motion, position the pointer close to the end of an audio track’s
green bar.
2. Press and hold the Option and Shift keys, and drag the end of the green bar to the left.
As you drag, the loop pointer appears, and a tooltip displays the track’s In and Out
points, duration, and loop duration.
The Audio Timeline displays looped tracks with barriers to indicate where loops begin
and end. The first loop barrier in a track’s bar is interactive. Dragging the barrier left or
right changes the point where the track loops.
