Ok, I've got Adobe Premier, After Effects, Sony Vegas 6d, and all that. I got a nice large green screen from the Adobe Suite... but here's the thing, I don't know how to use it ... I mainly use Vegas because Premier is so deep and I don't have time in my line of work to dedicate that amount of time to a production. I make all of our commercials through Vegas, I work a little with after effects. Could someone please tell me how to use my green screen. I'm shooting a commercial in 6 days and it will require the use of my green screen. Thanks!!
