Trim a QuickTime Video Clip

To trim a QuickTime video clip, open the video file in the QuickTime Player application.

  1. Go to Edit/Trim in QuickTime Player.
  2. Drag the yellow sliders to where you want to start and stop the movie.To fine-tune the start and stop, you can also use the left/right arrow keys to nudge the playhead left or right, then type “i” to move the starting point to the playhead’s position, or type “o” to make the ending point at the playhead’s position. Alternatively, you can click and hold on the yellow slider to get a zoomed in view of the playhead, and do more precise edits in that view.
  3. Save the edited movie.
