chromakey hardware?

I’m working on a live show where actors perform in front of greenscreens, I pull a key and do composites in touchdesigner- the audience watch the result on screens in real time.
It’s all going great but I’m struggling to get a really nice key out of the software.
I’m looking at the blackmagic utimatte to do that job, feed out RGB and matte channels for touch to use.
Am I right in saying touch doesn’t really do super nice keys?
is the ultimatte the best option?
Thanks

Hi, I presume you are using the chromaKey component in the Palette? chromaKey doesn’t have the degree of sophistication, finesse (or cost) that Ultimatte, Primatte or others have. chromaKey has a limited set of thresholds and controls, and deals with color spill in a simple way. Its suitability depends what your subject is and the uniformity of your background. I’m open to suggestions on its improvement, but the network is open so you are welcome to add features yourself.
