Very little of what you see on TV and in films these days is real. More often, actors are filmed inside huge studios, or in public areas sectioned off with green or blue panels or curtains.

This technique is also referred to as color keying, color-separation overlay (CSO), greenscreen, and bluescreen. The principal subject is filmed or photographed against a background consisting of a single color or a relatively narrow range of colors, usually blue or green because these colors are considered to be the furthest away from skin tone. The portions of the video which match the preselected color are replaced by the alternate background video. This process is commonly known as keying, keying out or simply a key.

Adobe After Effects is the digital motion graphics and compositing software published by Adobe Systems, used in the post-production process of filmmaking and television production. Its main uses are the origination of 2D and 2.5D animation, visual effects compositing and finishing, such as image adjustment and color correction, and is often used in conjunction with software like 3D Studio Max and Cinema 4D.
