This is my first time using iMovie, but after I put the clips together it doesn't seem to want to export the 58 minute file. It creates a file that is 1.4 MB instead of 8.7 GB. I tried to select all of the clips at the bottom and then export it to theater, and it picked a 1 minute clip that wasn't even selected or in the finished movie... The next thing I would like to do is reuse the opening and end credits as edited in this first movie, but that seems to not work the way I would expect it to either. Do I need to make a new library for every movie I create?
