Free video editing software?

Free video editing software?

I need some video editing software for a presentation I'm doing, but don't want to spend anything (I'm only going to use it once anyway). I've googled, but I wondered if anyone had awesome recommendations? Thanks :) Edit: Sorry, should have said before. Basically I want to cut a couple of seconds off beginning and end, put a black screen with text at the beginning, and add music.
