Mattes are solid color signals that can be applied to backgrounds and keys, and borders. Color selection is done either by picking a preset color, or by adjusted hue, saturation, and luminance to create a custom color.

Mattes can be applied to the following:

  • Background — Select the matte generator (BG) on a background or key bus. The full region of the background or key is filled with the selected color.
  • Border — Assign a border to a WIPE transition or a key. The wipe border is filled with the selected color.
