So after a couple of hours editing a video together, it's finally done. I started another video. Now, I need to go back and send the first video to compressor so that I can actually use it. Problem is, if I try to open it, Final Cut gets stuck in "Loading ___ into timeline" indefinitely. If the problem persists, I can't work on more than one project at once, which, well sucks. Not to mention losing hours of work from this video alone. Help?
