There happens to be a free version of Avid on their website. If you dont know what Avid is, it's a video editing program that is what the pros use for real movies. This is a free version that you have to register to get a key but its free to reg. Anyways I havent had a chance to use this one yet or see how usefull it is and usualy I would before recomending software, but seeing as this page needs a post I figured why not. Get it Here.
