m
Position the pointer over the number in either the In or Out field, and the drag pointer
appears. Drag left to increase the value, or drag right to decrease the value.
Scrubbing an Audio Track
You can scrub an audio track in the Audio Editor to hear a portion of the track. Use the
Audio Scrubbing button to turn scrubbing on or off. Scrubbing is turned on by default
in the Audio Editor (it is off by default in the Timeline).
To scrub an audio track:
1 In the Audio tab, select the track.
2 If scrubbing is turned off, click the Audio Scrubbing button, located at the lower-left
corner of the Audio Editor, to turn on scrubbing.
3 Drag the playhead in the Audio Editor left or right. Keep the pointer still to loop
continuously on the frames adjacent to the current frame.
Note: By default, audio scrubbing loops continuously on the 5 frames adjacent to the
current frame when you keep the pointer still. You can turn off looping by choosing
Motion > Preferences, clicking the Project tab, then turning off the “Loop audio while
scrubbing” checkbox under Playback Control.
You can also scrub audio in the Timeline by turning on the Audio Scrubbing button,
then Option-dragging in the ruler at the top of the Timeline.
Keyframing Level and Pan Changes
Each audio track has curves for both level and pan, and you can add and edit
keyframes to automate level and pan changes over time. This lets you create fade-ins
and fade-outs, drop audio levels for voice-overs and other sound effects, and eliminate
clipping. You edit the curves directly on the audio waveform in the Audio Editor,
allowing you to make accurate edits.
For more information about using keyframes and editing curves, see “
Keyframes and
Curves” on page 401.
The trimmed area appears highlighted in green.
