Background Matte
Background Matte
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 (Multi-Func-
tion Module,
Matt button in the Home menu) and from the Keyer, Matte
menu, which provides additional background parameter controls.
Multi-Function Module Matte Controls
1. Select the BGD 1 source on a background bus of any Stripe (its default
location is the seventh source select button from the right).
2. Select the Matt button on the Multi-Function Module to display the
Matte Mode.
3. If necessary, make the matte visible on the preview monitor by selecting
delegated ME button on the Switched Preview button group on the
System Bar.
4. Press the Flat button in the Multi-Function Module. This selects a flat,
single color matte ( Figure 141 ). All subsequent matte controls are
located in the Multi-Function Module.Adjust the Hue , Saturation , and
Brightness knobs to make the matte the desired color. This adjusts the
base fill color of the matte.
5. Press the Keyer Wipe button to select a wash matte type containing both
base fill and wash fill colors. The Keyer Wipe button illuminates to
indicated a wash has been selected (though the background matte is not
using the keyer wipe pattern generator). Note that pressing the
W1 Wipe
or W2 Wipe button also selects a wash matte type and illuminates the
Keyer Wipe button.
6. Press BWAS to delegate the Matte controls to the wash fill, and adjust the
Hue , Saturation , and Brightness knobs to create a contrasting color. If only
a single matte fill color is visible that doesn’t change, adjust the Offset
and/or Softness knobs to make the edge between the two colors visible
on the screen, then adjust the wash fill color.
7. Adjust the Rotation knob to change the angle of the edge.
