Changing the Duration of Clips in the Timeline

Clips are represented in the Timeline as horizontal bars within tracks. The length of the bar represents the clip item’s duration. The beginning and end of the bar represent the clip’s In and Out points. You can drag the beginning or end of the clip to change the clip’s duration, right in the Timeline. As you move your pointer over a clip, the pointer changes from an arrow (around the center of the clip) to a Resize pointer (at either the beginning or the end of the clip).
