I've started messing with Fraps, and I would like to combine my video pieces (even with the full version it breaks them up) into one big video in a slightly-compressed and common format. I tried Windows Movie Maker, but it seems kinda fail. Like, no video came out. Got audio just fine, though. Also, it only does wmv.
So, my question to you, Internets, is this: what free/open source video editing software would you recommend for doing this? I'd prefer something for Windows 7 as I don't currently have a nix box set up. I'm also fairly adamant about free vs. "free".
