In the Effects panel, double-click Video Effects > Keying > Ultra Key to apply it to the selected clip. In the Timeline, put the background clip on V1 and the foreground (green-screen) clip on V2.( In this example, I’m not using audio, but the process is the same whether you have audio or not.) Select the V2 (green-screen) clip. Note how dramatically she is lit, while the background is very even and flat. We want to remove the green background and replace it with something more interesting. This is why some of the foreground shots in this article are a bit green, I haven’t done final color correction to them. NOTE: The chroma-key effect uses the color of the source clip and ignores any color correction you add to the image. Garbage mattes are used to get rid of the junk. It only needs to completely surround the edges of your actors. Don’t worry about having the green background fill the frame.In general, don’t cast shadows on the green screen.This avoids light from the background “spilling” around their body or shoulders. Actors should be at least 10 feet in front of the green screen.(This example will illustrate that.) Always use separate sets of lights for background and talent. There is NO relationship between how the background is lit and how your actors are lit.I try to have the green background display between 40-50% level on the waveform monitor. The green background should be lit smoothly, both from side to side and top to bottom.Paint is always better than fabric avoid wrinkles and folds. The green background should be as smooth as possible.The best thing you can do to improve the quality of your keys is to improve how you light and shoot them. The big benefits to Ultra Key is that it is fast, flexible and looks great. In this tutorial, I’ll show you the preferred method: the Ultra key.

Premiere Pro provides several different ways to create this key.
KEYING IN PREMIERE PRO SOFTWARE
Because we can’t tell our software to: “remove everything that is more than ten feet away from the talent,” we use chroma-key instead. NOTE: The reason this process is necessary is that no camera shoots an image with depth. Green-screen key, also called a chroma-key, is the process of removing a background color from the image so that you can place an actor in front of another background.
