If both encoders are set to 19.10 Mbps and you want to reconfigure them to say 15.00 Mbps for
channel 1 and 25.00 Mbps for channel 2. This would cause an egress overflow condition
because you have not factored in the 3.5% reserve and bandwidth occupied by audio pids.
Even though VAF is set to off it’s logic will override the configuration request and constrain the
video rates back down to 19.10 Mbps for both channels. To obtain the desired configuration.
You would need to recalculate your rates. Then configure channel 1 to 15.00 Mbps then
channel 2 to 23.00 Mbps.
