Generate Background Mattes
Background matte generators create colors and washes. These can be used, for example, as
the backgrounds for keys.
Background mattes cannot use the wipe pattern generators available to keyer and wipe
mattes, and cannot use Utility video as a wipe source. Instead background mattes employ a
simple dedicated wipe generator that creates a single, straight line.
Background matte control is available from the Control Panel (Modifier area,
Matt button in
the Home menu) and from the Keyer, Matte menu, which provides additional background
parameter controls.
1 Go to the Mattes menu by pressing
Keyer, Mattes.
2 Select the BKGD button.
3 If not already selected, select the
Base Color data pad of the desired Background
(1 or 2). Use the top three soft knobs to adjust
Base Hue, Base Saturation, and Base
Brightness
of the base fill color.
4 Select the
Wash On button at the bottom so its indicator illuminates to create a wash
matte.
5 Select the
Wash Control data pad to bring up Offset, Softness, and Rotate soft knob
controls. If necessary, use the Offset and Softness knobs to make the wash edge visible
on the screen. You can also turn on the Rotate button, and then adjust the angle of the
edge using the Rotate soft knob.
6 Select the
Wash Color data pad to delegate the soft knobs on the right to adjust Wash
Hue
, Wash Saturation, and Wash Brightness of the wash fill color.
Because all background matte parameters are keyframeable, you can build effects with
constantly changing backgrounds using multiple keyframes.
