Trim Videos in Quicktime in Mac Os X Lion

QuickTIme in Mac OS X Lion allows you to easily trim your video clips, cutting out as much as you’d like from the beginning and end of the clip. While this feature is available for most versions of Mac OS X, the Lion version allows you to quickly access Trim from the playback bar. Read this guide to learn how to use this tool.

Steps

  1. Open your video file in the QuickTIme Player. You can trim any video or audio file that QuickTime supports. QuickTime is typically located in your Dock, and can also be found in the Applications folder.
  2. Open the Trim tool. You can access the Trim tool by either clicking the Edit menu and selecting Trim, or by clicking the arrow icon next to the Fast Forward button and selecting Trim from the menu. This will change the bar into the Trim tool.
  3. Click and drag the edges to trim the clip. You can trim from either the beginning or end of the clip. Once you are satisfied with the result, click the Trim button.[1]
    • The trimmed sections of the clip are not removed, but instead QuickTime will start and stop playback at these new points. This means that if you open the file in a different media player, the Trim adjustments you made will not exist.
    • Because the Trim function does not actually remove data, trimming your videos will not affect file size.
    • If you wish to revert your Trim adjustments, load the movie in another media player and Save it as a new copy. This new copy will no longer have the start and stop markers that you set with the Trim tool.
