5. Move the playhead to the point where you want the audio completely faded in, then do
one of the following:
• If you used the Record button method in previous steps, set the Level slider to the
level you want.
• If you used the Add Keyframe button method in previous steps, click the Add
Keyframe button again, then set the Level slider to 0.
A keyframe is added at the current frame.
If you used the Record button method in previous steps, click the Record button again
to turn off keyframe recording.
Listen to the crossfade as you work. You may find that the best-sounding results are
achieved by having the level curves for the two tracks be slightly asymmetrical. This is
because the perceived loudness of different sounds with the same numerical value can be
different.
Sync audio and video in Motion
Motion lets you determine how to handle the playback of audio when audio tracks are not
in sync with the video. You can skip video frames to resync with the audio, or pause audio
playback to avoid skipping frames if the video is out of sync.
Set audio sync preferences
1. In Motion, choose Motion > Preferences, then open the Time pane.
2. In the Playback Control section, select one of the following:
• Skip video frames: Video frames are dropped to enable an uninterrupted flow of
audio, for as close to real-time playback as possible.
• Pause audio playback: Audio playback pauses when video and audio are out of sync,
then begins when audio catches up on the next loop. This enables an uninterrupted
flow of video frames (at the expense of playback slowing down) to evaluate the look
of your composition.
