@Tvorsk @renbymon It's apparently digitally generated, then overlaid in the analog domain. Really nice. Zero degradation (they claim) of the input video.

@philpem @renbymon So the great looking edges are combination of (relatively) high res digital and just-right tiny amount of analog smear? :)

@Tvorsk @renbymon Something like that! Analog domain anti-aliasing, I guess? I'm curious how they implemented the keying hardware. Probably some opamps and multipliers. If you look at this - it can alpha blend in hardware.

@philpem @renbymon This sounds surprisingly whole-assed!
One one hand, "for serious professional use", on the other we all know that often means more gotchas than consumer market stuff because "operator should be aware".
