I really like Motion 5. Just the interface alone was worth the price. I did not buy FCPX, I just export videos like you said, and use them in FCP7. It seems to do things better – Match Move tracks better and keying seems more robust. Multiple audio files work fine for me. But I have been having video problems that have me perplexed. All is fine in my project, until I accidentally double click in the canvas on some area, I think where no objects are, which makes the screen go black. No matter what I’ve tried, i can’t see my work anymore. The only solution is to save, and restart. Have you seen that one?
