What I'm saying is there are not a lot of ways to dynamically assign those video devices/ports to certain vlans. You may look into VMPS, it can do vlan assignments based on mac address, but it requires a switch capable of being the server. Designate ports 1-X for video and put them in your video vlan. Configure them for priority queuing and the switch to "mls qos trust dscp".
