Software for webcam Logitech C920

It's all I can afford right now. The C920 comes with toy-like glitchy software and I'd like to use something like Sony Movie Studio 12 ($32 from Amazon). The 920 puts out mp4 files and they have opened in Windows Media Player and some other old junk I've got from LG. The 920 also uses encoding software called h.264. Movie Studio supports a ton of files, among them mpeg4. dumb question but is that the same as mp4? I want to make slide shows and short promo videos for my e-book.

Thanks.
