Keyer Controls and Operation
Auto Setup Mode
The auto setup mode is used to graphically select a color to suppress. The
Next Transition key button must be enabled (tally high) and the chroma keyer
must be selected and active ( Key Select button tally high). You must set up a
chroma key manually, as the Chroma Key Expert Level Panel application is
not available with this panel.
Entering Auto Setup Mode
Press and hold the Mode/Function button. Then press a Key Select button. The
Key Select button tallies high/blinking to indicate that the keyer is in auto-
setup mode. The LAP monitor shows the Fill (foreground) input of the
chroma keyer with a small cursor box superimposed over the video.
Moving and Re-Sizing the Cursor Box
Use the Clip/Foreground knob to move the cursor box horizontally (X-posi-
tion). CCW rotation moves the cursor box left and CW rotation moves the
cursor box right.
Use the Gain/Background knob to move the cursor box vertically (Y-position).
CCW rotation moves the cursor box up and CW rotation moves the cursor
box down.
Use the Brightness/Opacity knob to adjust the size of the box. The average
chrominance inside the box is calculated and used as the color to suppress.
CCW rotation decreases the size of the cursor box and CW increases the
size of the cursor box.
Exiting Auto-Setup Mode without Change
Press and hold the Mode/Function button. Then press the Key Select button.
The Key Select button tallies high and the LAP monitor displays the chroma
key. The chroma keyer setup will be unchanged.
Exiting Auto-Setup with Change
Press the Key Select button. The Key Select button tallies high and the LAP
monitor displays the chroma key. The key reflects the new chroma keyer
setup.
