Syncing Audio

When you add independent audio to any of the audio tracks on the timeline, it is

important to ensure that it syncs with the video in your production. CyberLink

PowerDirector displays the audio waveform on each clip that is added to the

timeline. The waveform is useful when trimming or splitting the audio clip, and

also when trying to sync audio to the video in your production.

Note: if you are trying to sync audio in an audio clip with the audio is a

video clip (because they have the same source audio), you can use Sync

by Audio to sync the clips.

You can even zoom in on the timeline for more precise syncing, as the waveform is

viewable down to the 1/10 frame level.

Note: if an audio clip's waveform is not displayed, it may be because this

option was disable in preferences. You can enable it again by selecting

Show sound waveform in timeline in General Preferences.

Once zoomed in, you can use the waveform in conjunction with Timeline Markers

to sync media more precisely in your video production.
