Merge the foreground over the background to produce your final comp. In some cases, this is all you need to do to perform a key, since selecting the screen color creates a screen matte and despills the foreground. This averages the pixels in the area selected to produce a better key. In the ChromaKeyer Properties panel, click the color swatch next to screen color to activate the eye dropper.Ĭtrl/ Cmd+ Shift+click and drag a rectangular area over the green pixels in the Viewer. From the Keyer menu, select ChromaKeyer and attach a Viewer. Start Nuke and read in the foreground and background images. The images below show a green screen foreground and the background to be composited over. ChromaKeyer is also available as a soft effect in Nuke Studio's timeline environment. ChromaKeyer can take advantage of modern GPUs and multi-core CPUs to accelerate the keying process when used for compositing in Nuke's Node Graph. This section explains how to use the blue/green screen keyer, ChromaKeyer, in Nuke.
