Reposition or remove beat markers

In the Project browser, choose Clip Trimmer from the Action pop-up menu (looks like a gear) for the audio clip you want to work on.

In the Clip Trimmer, drag the beat marker to a new position.

If you’re working with a background music track and “Snap to Beats” is turned on, when you reposition the beat marker, iMovie preserves the pacing of the markers because video is “pinned” to them. Therefore, if you move the marker to the left in a video clip, iMovie automatically lengthens the video clip that’s pinned to that marker and shortens the preceding clip by the same amount. If you move the marker to the right, iMovie automatically shortens the video clip that’s pinned to that marker and lengthens the preceding clip by the same amount.

In the Project browser, choose Clip Trimmer from the Action pop-up menu (looks like a gear) for the audio clip you want to work on.

Do one of the following:

• Remove a single beat marker by dragging it to the top edge of the Clip Trimmer, outside of the green waveform area.

  It disappears in an animated puff of smoke.

• Delete all the beat markers from any type of audio clip by holding down the Control key as you click anywhere in the audio clip in the Clip Trimmer, and then choosing Remove All Beat Markers from the menu that appears.
