Sep 4, 2014 10:00 AM in response to GeeDby Lower Terrace,I have the same problem. I'm using Mavericks OS and latest iMovie. Both downloaded last week. I save the movie into File (as directed) and QuickTime
will not open. I'm then directed to a page of formats which are supposed to be supported on which is .mp4. Any tips?
