Thanks so much for the advice! I'm going to mess around with Premiere and see what I can do. I'm thinking I'll import the entire beginning part (since it's all lip-sync stuff, and I can't remember what I did to make the mouth movements fit the words) and just add some transitions. But maybe redo everything else with separate clips. I still have the clips I edited, so I should be able to fit them in as long as I keep track of the order. And I might be able to make it look neater.

It's worth a try, anyway. And I'll keep a copy of the original just in case.

I do have to re-edit a bunch of clips since I didn't think of what you said about the subtitles when I was editing them out of some shots. It looks okay to me, but... better to be safe.

Thanks again!
