Hi @VideoFanatic . When you bring video into the system via an LZX TBC or Visual Cortex, it’s separated into 1V DC Luma, Red, Green, and Blue signals. This essential makes all four channels their own independent luma/brightness signals to route as you please within the system.
Then return whatever processed signals you want to the Red/Green/Blue inputs of the Compositor, and mix them out to the Decoder. At that point the final composition will be processed into a normal external video signal again (see this thread.)
