In this VideoFort.com After Effects tutorial VideoFort Jon shows you how to remove a green screen using After Effect built in Key Light. With the green screen footage selected, choose KeyLight from the Effects, Keying drop down menu. From there use the eyedropper tool to select a portion of the green screen. Then VideoFort Jon goes through some of Keylight’s setting to make a better green screen pull. After adjusting the settings, add a solid layer and put it underneath the green screen footage. On the new solid’s layer select Alpha Matte underneath the track matte settings. This gives you an outline effect that can be useful for many different projects.
