I have an assignment for vocational video photography course. We have to make short movie on anything. But it should have a least duration of 5 minutes. I spend so many days working on the idea on what I need to do. I have shot the movie already from a handycam in HD format. I need to edit the movie now so that it looks presentable. So, I need a video editing software for free. I dont need very sophisticated and fancy software with too many functions. I just need simple functions that are needed for editing. Please suggest a few good ones and links for the same please.
