HELP! I'm putting together a great Mother's Day movie where I've spliced together a number of kids' interviews into coordinated segments. The project itself looks and sounds great while in Movie Maker, it saves as a project perfectly, it opens perfectly....but it's not saving correctly as an mp4 (or anything else for that matter). All my carefully selected little clips get offset somehow! If I've inserted a clip say a 4 seconds long, it will save as the same length but offset by a fraction of a second, which is enough to jumble up the entire thing!!!

I've tried saving it for computer, for high definition, to Vimeo, to Facebook, and just about every other format offered. I've even tried removing and replacing the clips in case something happened with the source. Nothing. 

Mother's Day is Sunday, and I thought I was all but done! Can anyone help?
