I'm trying to make a very simple movie. I dumped a bunch of clips into iMovie, and have lined them up in the timeline. I can't seem to export them to youtube or anywhere else, for that matter. What am I doing wrong? After I get a bunch of clips lined up, what's the next step for uploading them? I'd like to get them into youtube. I have an account set up, and I'm logged in. I just figure out how to do it.
