Border (Brdr) Button
The Brdr button ( Figure 2-11 on page 2-24 ) is operable if the Border and
Dropshadow software enabled option has been purchased and enabled.
Selecting the
Brdr button adds a one-line border to the key. The Shadow
button is not used on this panel.
This button only has an affect if the selected keyer is in key modifier mode.
Pressing a previously unselected button toggles it low, and toggles the
other button off (if it was low).
The luminance of the border can be adjusted with the Brightness knob or a
default luminance can be set or recalled as explained below.
To delegate the Brightness knob to the Brdr button, select the button. If the
Matte button is tallied off, the Brightness knob automatically delegates to
adjust the luminance of the border if either is selected. However, if the Matte
button is selected (low tally), the Brightness knob is delegated to it by
default. The Brdr button must be held down in order to redelegate the Bright-
ness knob to border luminance. While either Brdr button is held down, the
Hue and Saturation knobs become inoperable.
Make luminance adjustments with the Brightness knob (while holding down
the Mode/Function button). Release the Brdr button and it will continue to tally
low. If no adjustments were made, Brdr will tally off when released.
Border Luminance Default
The keyer must be in modify mode. The Brdr button must be tallied low or
off and released.
1. Press and hold the Mode/Function button.
2. Press the Brdr button.
3. The luminance value for the border will be set to the default value. The
Brdr button continues to tally low or off.
SELF/EXT and LIN/LUM Buttons
The SELF/EXT and LIN/LUM buttons determine the key source and whether the
key is linear or based on luminance values. These buttons are operable only
in key modifier mode.
If the SELF/EXT button is pressed, the keyer is configured for an external key
(key source is from an external device). When disabled, the keyer is config-
ured for a self key. The SELF
/EXT button toggles low/off on a button push.
If the LIN/LUM button is pressed, the keyer applies S-shaping during key
processing making a luminance key. The LIN/LUM button toggles low/off on
a button push. If the button is not pressed, the key is unshaped (linear key).
