Moving clips in the Timeline
You can easily move clips in the Timeline. For example, you can move a clip to align it with clips on other tracks, to close gaps after trimming, or to overlap one clip with another to create a transition.
* To move a clip
1 In the Timeline, do any of the following:
Move a clip: Click a clip, and drag it to a new position or to a new track.
Move a clip one frame at a time: Click a clip, and press ALT while using the right or left arrow key to move the clip.
Remove all gaps in a track: Right-click the track head, and in the context-menu, choose Remove all gaps.
