"Missing Files" in iMovie Project

You do have a user library folder. I don't know why it is not showing in the menu. However, try clicking on the Macintosh HD icon on your desktop. In the drop down that appears, click on Users>then your name>Library. Follow the Backups file path from there. You want your User library, not the system library.

That is frustrating. Hope I can help:

Can you start by going to your Desktop and clicking on your background? After that, please click:

Go (Top Menu) > Computer > Users > Your Name > Movies > Right Click on iMovie Library > Show Package Contents > Original Media. Are the video files in there? If not, please click hold and drag them into this folder.

The good news is that the media is still there. You are dealing with a broken link between this specific project and the iMovie library.

Try deleting preferences and see if that cures it. Deleting preferences is a safe procedure that will not cause data loss or disruption to your project. To delete preferences open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects.  Now see if the clips display properly.

If no luck, look in the iMovie Backups folder and open an earlier backup of the library that contains the project. To get to the iMovie Backups folder, follow this file path from the Finder menu:

Go/Home/Library/Containers/com.apple.iMovieApp/Data/Library/Caches/iMovieBackups

When you get there you will see a list of previous backups of your iMovie library.  Click on one dated just before your issue started.  iMovie will open in that library.   Navigate to your projects browser (where your projects are displayed as icons) and see if your projects are intact.

Try using the Library listed under the Go item in the finder menu, and then follow the file path from there.

Great! Glad you got to the bottom of it. 😊
