Check camera and media format compatibility
Make sure you're using a camera and media format that works with iMovie. If you can't find your camera listed or need further assistance, contact the manufacturer of the device for support.
If you're using a third-party video interface with your Mac, check with the manufacturer for firmware or other software updates for your device.
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:
- Quit iMovie.
- 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.
- In the Open Library window, click New to create a new library.
- 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:
- In iMovie, click Projects to return to the Projects view.
- Choose File > New Trailer, click the Action trailer template, then click Create.
- 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:
- Click projects to return to the Projects view. In the window, click OK.
- Choose File > New Movie.
- 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.
- Select the clip in the browser, then press the E key to add the clip to the timeline.
- 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.
If the new library and project work as expected, you've isolated the cause of your issue to the original library or project. Try to restore a previous version of the original library from a Time Machine or other backup.
Test iMovie with a new user account
Create another user account on your Mac, then test iMovie with the new user account.
