Undo Action in Project After Closing iMovie
I'm working on a very long and complex project, so I decided to export each chapter separately. I copied one chapter, deleted everything, pasted that chapter, exported it, then command+z'ed my way back to where the full project was still there. I repeated this processes with all chapters until I'd exported them all. Then, once the final chapter was exported, I closed iMovie, forgetting to command+z back to where the full project was there. Now I reopened iMovie and can't go back any further, but I need to access the full project, because the parts I exported weren't finished and it would be a lot of work to start over and re-edit them. Please tell me there's some way to retrieve them!
