Filming

So I had done all of my filming and put my music in and added my transitions... however, when it came to saving in high def the files would not save. I am now looking at doing it through Quicktime player and Final Cut Express. It is all very stressful and confusing especially when my movie was exactly how I wanted it and now I have to start again. I am hoping that this idea will work though and all of my issues will be revolved.
