Matte Wash
You can produce a matte with graduated shading between two or
three colors, called a matte wash. This effect works well as a
background for keys and digital effects. As an example, two
methods are given below for creating a “sunset” wash:
Matte Wash Method 1
1. Select Transition [BKGD] and [WIPE] .
2. Select wipe pattern 0 (second pattern from left in the top row
of patterns) and
[REVERSE] . All other wipe modifiers should be
off for now.
3. Move the lever arm to about mid-travel to advance the wipe
about half way up the screen.
4. Select the Bkgd matte [CROSSPOINT] on the PGM bus, and set
the Matte controls for a dark blue color at the top of the screen.
5. Select a Matte [CROSSPOINT] on the PST bus, and set the matte
controls for a reddish-brown color at the bottom of the screen.
6. Select the Pattern [WIPE] button. Turn on the [BORDER] button,
and set the pattern edge (WIDTH) control for a 1-inch wipe
border. Use the Matte controls to make the border yellow.
7. Turn on the Pattern [SOFT] button, and adjust pattern edge
(SOFTNESS) to soften the entire screen. This completes the wash
effect. You can use the downstream keyer to key over the top
of the wash.
