I have a new retina macbook pro and am trying to add 2,300 pictures to an iMovie project to make a time lapse video. The import is amazingly slow. It's been 20 minutes and only halfway done and it says it will take another half hour. This doesn't seem right at all. I could drop this many pictures into Windows Movie Maker and they would import instantly. The macbook is also getting extremely hot during the import. Should I suspect something is wrong? Any advice? Thanks.
