Part 2: How to Trim a Video with QuickTime on Mac

QuickTime is the built-in media player on Mac. In addition to playing video and audio files, it also provides the ability to trim a video file. That makes it the easiest choice for beginners but it does not offer any other features involved with video editing. Bear in mind that the media player only supports limited video formats, such as MOV, M4V, a part of MP4, etc.

1. Run the media player app from your Applications folder, and open the target video.

2. Go to the Edit menu and choose the Trim option. Then you will see the timeline.

3. Drag the yellow handles to choose the clip that you want to keep. The content will be highlighted by the yellow rectangle. Click the Trim button until you are satisfied.

4. At last, save the edited clip as a new video file.


When setting the new start and end positions, you can also use the left and right arrow keys on your keyboard to find the desired frame exactly. To zoom in a specific frame, click and hold on the yellow slider.

Actually, QuickTime is a great player instead of a professional video editing tool. And it only provides the video trimming feature in the built-in version. If you want to compress or crop videos in QuickTime, upgrade to the Pro version for $30 to access more editing features.

Part 3: How to Trim a Video by iMovie on Mac

iMovie is the built-in video editor on Mac, so it is another way to trim a video on Mac without extra apps. Although it is not as intuitive as QuickTime Player, you can follow the steps below to get it easily.

1.Open iMovie from your Applications folder, go to the Projects pane, click Create New, and select Movie to create a new project.

2.Drag and drop the video that you want to trim into the video editor, and put it on the timeline.

3.Drag the play-head bar to the new start point, right-click and choose Split Clip on the context menu. Select the clip in front of the play-head, right-click and choose Delete.

4.Next, drag the play-head to the new end position, right-click and choose Split Clip too. Select the clip behind the play-head, right-click and choose Delete.

5.Preview the clip in the composition panel, and click the Share icon at the top right side if you are satisfied. Now, choose a proper channel to export the trimmed clip. To save it to your Mac, select File and follow the instructions to finish.

iMovie is easy to use when trimming a video but requires a high HDD space. It makes the platform slow and takes up plenty of storage. Sometimes, you must compress the video to reduce size before exporting.
