To change the playback speed of a clip in iMovie, follow these steps:
- Select the Clip: In the iMovie timeline on your Mac, click on the clip you want to speed up or slow down.
- Access Speed Controls: Click the "Speed" button located above the viewer. It looks like a speedometer.
- Choose a Speed Option: A Speed pop-up menu will appear. Choose either "Slow" or "Fast."
- Select the Speed: Click one of the available speed options presented as buttons (e.g., 1/8x, 1/4x, 1/2x for slow motion; 2x, 4x, 8x, 20x for fast motion). The clip's duration in the timeline will adjust automatically to reflect the speed change.
That's it! Your clip's playback speed is now adjusted.
