Change duration and speed of clips
Changing speed of clip
Changing clip speed changes the clip’s duration. Speeding up a clip removes frames, thus shortening the clip duration. In the same way, slowing down a clip repeats frames and thus adds to the length of a clip. For audio clips, a change in speed also changes pitch. The Time Stretch command includes an option to maintain the original pitch of an audio clip at any speed.
Note: When you change the speed of a clip containing interlaced fields, you may need to adjust how Adobe Premiere Elements processes the fields, especially when the speed drops below 100% of the original speed.
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.
- Select a clip in Project view of the Tasks panel or in the Timeline.
- Choose Clip > Time Stretch.
- 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. - 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.
- Select the clip in the Timeline.
- Choose Clip > Time Stretch.
- (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.
- Select Reverse Speed, and click OK.
