354582 need video editing software

What I'm trying to do is create multiple videos automatically. Say for example I wanted to build 100 videos, all very similar, but each different enough that they'd get accepted into a video-sharing site like youtube. So what I'm trying to do is find a fast, and simple way to do that. Ideally I'm trying to find some kind of software that will build these multiple videos at once. So for example I'd like to find a software that will build say 100 similar videos automatically. Do you know if there's any kind of software that will do this? Most software like windows movie maker for example only allow for building one at a time. I'm trying to find a way around this. If you can either show me a software that does this automatically, or a way to do this within some kind of free editing software such as: windows movie maker, then you're the person I need to show me. Thanks.
