Chapter 13 Working With Audio 893
Note: You can also show and slip the timebar for an audio track in the Timeline by
clicking the Audio Scrubbing button at the lower-left edge of the Audio Editor.
Trimming Audio Tracks
You can edit the start and end points of an audio track to cut down the length of the
audio in the track, or to have it start or end at a specific point in time. This is called
“trimming” the track. Motion lets you trim audio tracks, either visually or by entering
numeric values for the In and Out points.
When you trim an audio track, the audible part of the track is highlighted in green in
the Audio Editor. Trimming an audio track is non-destructive, and does not affect the
original audio file.
To trim an audio track visually:
1 In the Audio tab, select the audio file you want to trim.
The track’s bar appears in the Audio Editor and in the mini-Timeline.
2 In the Audio Editor or the mini-Timeline, position the pointer over the beginning or
end of the timebar, and the Trim pointer appears.
3 Drag the beginning or end of the timebar to the point where you want to set the In or
Out point for the file. The progress of your trim is displayed in the Audio Editor, and lets
you see the time markers, so you can trim more precisely.
To trim an audio track numerically, do one of the following:
m
In the Audio Editor, type a value in the In field where you want the track to begin, or
type a value in the Out field where you want the track to end.
m
Click the increment arrow at the left edge of the field to increase the value, or click the
decrement arrow at the right edge of the field to decrease the value. Shift-click to
move in increments of 10.
