⇒What Is Keying In Adobe After Effects?
⇒Keying is a technique that is used in
a lot of special effects.
⇒Keying is used to remove certain colors
from the video(such as green screen background)
and then replacing the colored area with new visuals.
⇒Green screens all use some form of keying where
green background is removed from the video.
⇒It's a quick way of Rotoscoping.
⇒Green color is chosen for Keying
because Green is an easy color to avoid.
⇒However,the background doesn't have to be green for the
effect to work.Some special effects teams use magenta
screens,and blue and red are fairly common as well.
