Animate audio level and pan in Motion
You can use keyframes to automate level and pan changes over time. Audio keyframes for
level and pan changes are visible in the Audio Timeline and Keyframe Editor. You can adjust
these keyframes (and their curves) to create fade-ins and fade-outs, to drop audio levels
for voiceovers and other sound effects, and to eliminate clipping. (For general information
about using keyframes and editing curves, see Intro to keyframing in Motion.)
Add audio keyframes
1. In Motion, move the playhead to the frame where you want to record a keyframe.
2. Select an audio track in the Audio list or Audio Timeline, then do one of the following:
• Click the Record button in the timing toolbar, open the Audio Track Inspector, then
adjust the Level slider or Pan slider.
• Open the Audio Track Inspector, adjust the Level slider or Pan slider, then click the
Add Keyframe button (the diamond icon) to the right of the slider you adjusted.
A keyframe is added at the current frame. To see the keyframe in the Audio Editor, click
the Show Keyframes button in the upper-right corner of the Timing pane.
3. Move the playhead to a new frame.
4. In the Audio Track Inspector, drag the Level slider or Pan slider to set a different value.
A keyframe is added at the current frame.
If you turned on keyframe recording in step 2 by clicking the Record button, click it again
to turn off keyframe recording.
Edit audio keyframes
After you add Level or Pan keyframes, you can change their values in the Audio Timeline
or Keyframe Editor. In the Audio Timeline, keyframes appear in sequence along a flat line,
showing their relative positions in time. In the Keyframe Editor, keyframes appear in a two-
dimensional graph showing their positions in time (horizontally) and their parameter values
(vertically).
In Motion, do one of the following:
• Edit keyframes in the Audio Timeline: Drag keyframes left or right to adjust their
positions in time.
If you added Level and Pan keyframes at the same frame, dragging the keyframe in the
Audio Timeline adjusts all audio keyframes at that frame.
• Edit keyframes in the Keyframe Editor: Drag keyframes left or right to adjust their
positions in time; drag keyframes up or down to change their Level or Pan values.
