If you have added high-frame-rate clips to your movie with the automatic slow-motion setting turned off, you can apply this setting to selected clips.
In the iMovie app
Click the Speed pop-up menu and choose Slow.
Click the Auto button.
The frame rate of the selected clip is adjusted to match the frame rate of the rest of the movie.
Note: If the clip has a duration longer than 3 seconds, iMovie adjusts the speed at the beginning and end of the clip, to emphasize the slow motion.
