hi, i'm new to this forum and film making in general. my friends and i are making a movie for fun (not to market) and we have an idea but don't know how to go about it. We are kind of just experimenting right now and the current experiment is that we have movie clips of ourselves but i want to change the background and make us look different (body shape skin color anything really). Does anybody know how to do this/what programs i need?
thanks

Adobe After Effects / masking and green screen-fun probably

check this website out http://www.detonationfilms.com/missionstatement.htm has tons of free effects for use.
