  2. To unveil the speed settings, hit the Speed button.
  3. Adjust either Slow or Fast in the Speed prompt menu, and select a speed button to reset the rate.

If you select Fast for shots less than 0.1 seconds, it applies the Custom speed by default and allows a predetermined rate. An icon pops up on your clip with a speed slider atop. Speeding up a clip makes it shorter and slowing down stretches out.

A clip with audio decreases the pitch if you play it more slowly while speeding it up raises it. To retain the initial pitch of the file, choose the Preserve Pitch checkbox over the viewer.

Solution 2: Tweak a Clip’s Speed Adjustments

You can also speed up video without changing pitch in iMovie. In the timeline, yank the speed slider at the crest of a clip that has rate adjustments. Yanking the slider to the right reduces speed, and dragging it to the left accelerates the clip. The speed slider comes in handy for custom rate adjustments.

  1. Highlight a range within a clip in the timeline by pressing the R key and dragging along the footage.
  2. To unveil the speed adjustments, hit the Speed button.
  3. Choose any of the following:
  • Slow up the highlighted portion of the clip: Hit the Speed pop-up menu and select slow.

By default, the speed remains 50%, but you can hit any speed button.

  • Increase speed for the highlighted portion of the clip: Hit the Speed pop-up menu and select Fast.

By default, the speed remains twice normal speed (2x), that means you can speed up iMovie more than 2x, but you can hit any rate button.

  • Adjust a custom speed for the highlighted portion of the clip: Select the Speed pop-up menu, pick out Custom, and feed a figure in the field.

Modify the Speed of Part a Clip

The speed change affects the highlighted portion of the clip, and speed sliders thrust above the selected range of the clip beyond this scope. If you playback the clip, it starts running at normal speed, then changes to the speed you prearrange before reverting to its normal rate again as it tails off.

  1. To have the speed adjustments occur incrementally, choose the Smooth checkbox.
  2. To modify the speed of the highlighted range or an area beyond it, yank any of the three sliders at the top of the clip.
