Move iMovie Library to An External Drive

If you have limited free disk storage space on your Mac, it is a good idea to get an external drive that is a least 500GB to store your iMovie library. To move iMovie library to an external hard drive.

  • Format an external drive as MacOS Extended (Journaled).

  • Close iMovie. Go to Finder > Go > Home > Movies.

  • Drag the iMovie Library folder to the connected external hard drive. Then you can delete the folder from your Mac.

Test with a new library and project

You can create a new library and test project to check if the issue is with your library, project, or iMovie app. First, create a new library:

  1. Quit iMovie.
  2. While you press and hold the Option key, click the iMovie app in the Dock or double-click the iMovie app in the Applications folder.
  3. In the Open Library window, click New to create a new library.
  4. Name the test library 'Test iMovie Library,' then save it to the Desktop.

Next, create the test project using a built-in trailer template, then export it as a QuickTime video file:

  1. In iMovie, click Projects to return to the Projects view.
  2. Choose File > New Trailer, click the Action trailer template, then click Create.
  3. Choose File > Share > File, click Next, name the file 'Finish Line,' then save the video file to the Desktop.

Next, import the QuickTime video file into a new project in the new library:

  1. Click projects to return to the Projects view. In the window, click OK.
  2. Choose File > New Movie.
  3. Choose File > Import Media, then click Desktop in the Import window sidebar. Select the 'Finish Line.mov' file in the list, then click the Import Selected button.
  4. Select the clip in the browser, then press the E key to add the clip to the timeline.
  5. Try to recreate the issue you were having. For example, if iMovie quit when adding a transition, try to add a transition to the timeline.
