Anybody know of a decent open-source (read "free") video editing program? I've done some looking around and found a couple of ideas but they crashed or just didn't offer what I want. Splitting files, arranging clips, and adding transitions are nice, but I'd like more features than that - you know, changing speed, lighting / colour effects, and other goodies.

I don't know if such a beast is out there, but I thought I'd give it a shot.
