How to Shorten a Video Length by Trimming in QuickTime for Mac OS X

If you need to remove unwanted parts of a video, such as a long intro or end captions, you don’t have to use a comprehensive editing tool like iMovie. QuickTime has a simple trimming feature that allows you to shorten the overall length of a video clip with just a few clicks. Just follow these easy steps:

How to Trim a Video Clip in QuickTime for Mac OS X

  1. Open a video with QuickTime or convert it using a video converter application to make it compatible.
  2. Go to the Edit menu and select Trim, or use the command Command + T.
  3. Use the yellow bars to mark the part of the video to be trimmed and click “Trim.”
  4. To save the trimmed clip, go to File and select Export.

You can play the video or swipe through it to make sure that you have trimmed the right part. If needed, you can shorten the clip further by repeating the Trim process. QuickTime trimming works similarly on iOS devices, so it’s easy to switch between them.
