Set the duration of a clip
The duration of a video or audio clip is the length of time it plays from its first frame (In point) to its last frame (Out point). The initial duration of a
clip is the same as it was when the clip was imported or captured. Most often, you change a clip’s duration by trimming frames from either end.
But you can also trim the end of a clip by designating a specific duration.
Unlike video, still images are not limited to the length of the original clip. You can set their duration to any length.
1. Select a clip in Project Assets panel or in the Expert view timeline.
2. Choose Clip > Time Stretch.
3. In the Time Stretch dialog box, click the Link button to unlink speed and duration. When linked, changing the duration also changes the
playback speed of the clip.
When you increase the speed beyond a certain limit, the duration changes even if you have unlinked speed and duration.
4. Type a new duration, and click OK.
Reverse the playback of a clip
Reversing a clip plays the clip backward, Out point to In point. You can also reverse the clip and change its speed. In the Expert view, you can
reverse a clip using the Expert view timeline. In the Quick view, use the Time Remapping feature to reverse a clip.
1. Select the clip in the Expert view timeline.
2. Choose Clip > Time Stretch.
3. (Optional) To change the speed of the clip, type a percentage for Speed in the Time Stretch dialog box. A value less the 100% slows down
the clip; a value greater than 100% increases its speed.
4. Select Reverse Speed, and click OK.
To both reverse the clip and change its speed with one action, type a negative percentage for Speed, where –200 plays the clip in
reverse at double its normal speed and –50 plays the clip in reverse at half its normal speed.
