I've been using the ATEM series of switchers since the first ATEM Television studio first came out. We have been using them as hardware keyers in the Reflecmedia booth at NAB. Years ago, there was a product for $1800 called the "Ultimatte DV". It was a pretty decent keyer back in 2008. Times have sure changed since then. HD. Then 4K.
