Video Lan, creators of VLC Media player, have created VLMC(Video Lan Media Creator). Before I begin, I have to warn you. This software is still in pre-alpha, which means it is not stable and still some features are not implemented. VLMC is like Windows Movie Maker. It is a free open Source video editing software. I have tested it out and I see a lot of potential in this software and when it's done i bet it will be better than Windows Movie Maker. Give it a try here or wait till they release the final version. It it available on Mac, Windows, and Linux.
