Join Steve Wright for an in-depth discussion in this video KEYLIGHT: Setting up a basic composite, part of VFX Keying: Master Course.
- [Voiceover] Key light is a color difference keyer…developed by the computer film company…that is distributed and supported by The Foundry…and is now available for Nuke.…We'll start by setting up a basic composite.…You can pull in these two elements…from our keylight media file.…So we'll select the green screen boy,…come up to the keyer tab…and select the keylight node.…Keylight hooks into the source input,…which is where the green screen goes.…And then we hook up the BG input to the background.…
The first step in keylight is to tell it…what the backing color is, what they call the screen color.…And here is the screen color here.…First we turn on the eyedropper.…Make sure that's turned on.…And then in the viewer command click to select the color.…Now keylight is twitching because it's actually…sampling the output of keylight,…which is being changed based on my selection.…So we have to use the Nuke keys alt + command…in order to sample the incoming image…that is directly off the source image right here, kay?…And if of course we want to sample a box…
