5 Using Keylight
This tutorial covers the basics of using the Keylight node,
including how to pull keys, apply masking, create
holdout mattes, and perform spill suppression.
The Keylight node is a plug-in developed by Framestore CFC. In addition to pulling keys
in the examples, you’ll learn a few masking and color-correction tricks that can be
applied to other nodes as well.
The first example in this tutorial uses images from the television miniseries, Merlin,
courtesy of Lions Gate Entertainment. The second example uses images from the motion
picture The Saint, provided by Framestore CFC and Paramount British Pictures Ltd.
