But I’d caution you not to move, rename or delete anything in this file unless you know what you’re doing. There you’ll be able to see each project and all of its assets.

If you want to go into the library file, you can do that by right-clicking or holding down the Option key and clicking on iMovie Library.

You can find the library file in your Movies folder in Finder or by clicking Go > Home > Movies. It creates a library file that stores all your projects and the corresponding assets for each of them. IMovie acts in the same way that Photos does. But in no way should it be used to replace frequently saving your project on your own. With that much strain on the app, it could cause iMovie to become unstable and crash more frequently.Īll that to say, autosave is a great backup. Plus, the more video files you add to a project, the heavier the file will be and the more resources that project will require to run. But you should still get into the habit of periodically hitting command+S to save your projects.īecause the autosave is based on time, it’s possible you could do a ton of work on a video and have iMovie crash in between autosaves, and then ultimately losing all of that work you did in the interim.
