4.8.1. Internal Keyer Routing / Priority
Each physical keyer (keyer 1 - 2) can select which fill and key signal can be applied to its input. The
two keying levels have a hardware determined priority where keyer 1 is the lowest priority (first to be
applied to the video chain) and keyer 2 has the highest priority (last keyer to be applied to the video
chain). However by changing which fill and key signal is routed to each of the physical keyers you can
change the priority of the two key and fill signals.
If any of the physical keyers are not being used then make sure they are selected to the "Not Enabled"
position, as this will prevent the keyers from being selected on the control panel or via the automation
system. This will also change which of the inputs can be used as PGM/PST inputs.
