The first step when keying with Ultimatte is to sample the screen color, or tell Ultimatte what color your blue or green screen is. Do the following:
| 1. | When you’ve connected the Ultimatte node, the foreground image is displayed in the Viewer. |
| 2. | Click Screen in the Ultimatte toolbar above the Viewer, and select the screen color by holding down Alt+Ctrl/Cmd and clicking in the Viewer. |
You should select an area on the green screen near important subject detail that is not obscured in any way. The image is rendered and a composite is displayed. If further adjustments are needed, use the controls described below.
After you’ve sampled your screen color, you can start adjusting your result. With the controls on the Ultimatte tab you can select different sets of controls you want to enable on other properties panel tabs. There’s also an enable checkbox on each tab that you can use to activate the controls on that tab and the corresponding tools in the Viewer.
