Hello I am pretty new to the 5D2 and I have been using its video mode more and more. I have a small green screen setup at home and I want to make some videos with it can anyone offer some help in a program thats pretty simple to use that can aide me with chromakey? I havent done much video editing other than windows movie maker so something cheap or free thats easy to use. Heck I will spend some extra bucks if its easy to use. Google hasnt been pointing me in the direction I want to go. Thank you!
