imovie duplicate movie

What steps are you doing to duplicate the movie?

Try opening iMovie while holding down the Option and Command keys and selecting 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 you can duplicate the movie projects that previously would not duplicate.

As I mentioned in my earlier post, what steps are you taking to duplicate your project?

For a workaround, you can open your original project and do an Edit/Select All, Edit/Copy, of all the media in your project at one time, and then Edit/Paste it into a newly created project. Your edits will carry over. That will give you a duplicate project.

You are welcome. :)

Sometimes things suddenly, inexplicably, don't work. So we take what the software gives us and do it another way, like you did.

Maybe a frame rate issue?
