Chapter 8 Timeline 255
Manage audio-video links
Ordinarily, objects that contain both audio and video are linked so they remain in sync. This link
is represented by an icon in the Timeline layers list.
Link icon
Note: To display the Audio Timeline, click the Show/Hide Audio Timeline button, located in the
lower-right corner of the Motion project window.
Objects that are linked are always edited together in the Timeline. Operations such as cut, copy,
paste, and split affect both audio and video. However, if you ever want to break that relationship
so you can move or edit the audio or video without the other tagging along, you can disable
that link and move either object freely. Beware that this might result in your audio and video
playing out of sync.
Manipulate audio and video elements separately
1 Click the link icon to the right of the object name for the video or audio element.
A red slash appears over the link for all linked layers.
Red slash indicates
link is broken.
2 Move, trim, or slip the audio or video bar.
