I am in the process of creating some video tutorials and I have download something which works great for recording the video, it's called liteCamHD. Anyhow, I now need some software to edit those videos. I don't want to spend hundreds of pounds on something like Adobe Premier, ideally I want it either free or very cheap, preferably on a trial.

Does anybody know of any such software? I am completely new in this field, which is why I have to ask.
