In this post, we’ve rounded up tutorial videos demonstrating chroma keying techniques in the most popular professional video editing applications.
For those unfamiliar, chroma keying, or “green screening” as it’s often referred, is the process of stripping out a solid color from your video image (thereby creating an alpha channel) so that it can be overlayed on another image or background. Usually done with either a solid green or blue background, the quality of your key will depend on a range of factors including the on-set lighting setup, the camera (and camera settings) used, as well as the software and settings used to “pull” the key in post.
As editors, we can’t always control these first two factors and often must rely on our post software to achieve the best key possible. Each of the applications below has built-in chroma keying functions, that offer a varying degree of settings and controls. For complex chroma keying and green screen work a compositing application such as Nuke, Smoke or After Effects may give you more precise tools. However, for simple chroma key work the filtrs that come standard with Final Cut Pro, AVID and Premiere might be all you need to pull a clean key.
We’ve crawled the ‘net to bring you the following quality video tutorials that teach how to use the chroma key function in each of these applications. Discover how to adjust the feathering, choke and spill settings to get clean edges and preserve detail and color. Chroma keying is not a cookie cutter operation! Different footage will require different settings based on the conditions in which it was shot (and how it will be used in the final product). With the following tutorial videos you should quickly be on your way to being a chroma key pro!
