Join Steve Wright for an in-depth discussion in this video Ultimatte: Basic setup, part of VFX Keying: Master Course.
- [Instructor] We'll start by taking a look at the basic…setup for an Ultimatte composite.…The first thing we wanna know is how to connect things up,…so if you'll select the read note for your bluescreen,…you can go up to the keyer tab,…select the ultimatte node, and it'll hook itself in…to the foreground input.…Here we go.…The BG is the background input.…We'll connect that up here.…We'll take a look at these others in just a minute.…Now I'm using a checkerboard as a test background.…I've set the floor mat to match my foreground image,…and I've set the size of the squares to 16.…
Using a checkerboard like this…is a better way for getting your initial key setup,…rather than doing it over the actual background,…which has different colors and luminocities…that may hide defects.…So let's take a quick look at the tabs…in the Ultimatte node.…The first tab, Ultimatte, is used, basically,…to set the screen color, and it has a few other controls,…which we'll come back to.…The density tab is used to dial in the density of the mat,…
