The best way to get a clean chroma key is to…
1. Make sure your lighting is consistent over the entire surface of the green screen. Avoid any bumps or wrinkles in the surface.
2. Move talent away from the screen to make sure reflected green light does not spill on the talent.
Any of the Chroma key effects in PP or AE will give you good results if you follow the above advice. My personal fav is Primatte, but thats an extra purchase.
