the real spirit - stallion of the cimarron.(part 1)

I’ve finally made Part 2, but something is wrong with my movie maker and I can’t convert it from “project“ to “film“. I have absolutely no idea why I can do it with all my other movies and ’error’ is only when I’m trying to save “the real spirit“. maby it’s bacause it’s longer than my fundubs and covers. if you have any freeware “like-movie-maker“ programs, which I could use, please recommend it to me so I can finally finish this. please read: With real horses. Yeah, I know Spirit changes his colour too often, but just use your imagination:P I found all videos on youtube. They’re not mine. I DON’T OWN ANY OF THIS VIDEOS or soundtrack (which belongs to dreamworks).
