you cant really get anything software for free unless you it already comes with your computer like I-movie, or windows movie maker. or also if you down from limewire or something. but i think final cut pro is the best. the easest program to edit to is adobe premiere elements.
window movie maker is good for people who are just starting video editing but it suck balls compare to other stuff but thats free so, so go to lime wire and download adobe premiere pro. if you dont already know how to use adobe premiere, your better off using window movie maker.
