I don't know if anyone here is interested in fan-edited films, but I've been working on an X Men edit that combines X Men Origins with X1 while removing all the stupid and unnecessary stuff from Origins and the things that contradict X Men First Class from both films. It's called "Children of the Atom" and is intended to be a sequel to First Class. There's a lot more to it but in case you're not interested that's about as short a description as I can muster.
Songwriting in my band, voice acting, school, making a game, and now fan edits? Yes, I'm a busy man. But that's not my point.
I was having trouble inserting music in some parts where score got in the way, with no good way to turn it down without losing voiceover, and Audacity kept freezing while importing video files. BUT...
I updated audacity and NOW it works like a charm, even split the surround sound so I could extract the voiceover without music! Or extract the score without the voice. It's extremely flexible, but it's STILL the easiest sound editor I've ever used! And I've paid for a lot of sound editing software.
I love open source.
