I'm curious to know if there's a site showing the quality difference between 4:4:4 and 4:2:2 keys. Unfortunately there aren't any affordable full color keying options at this time for small budget productions, so I'd like to see just how bad the damage is with 4:2:2. I'd love to see a comparison of an identical image (or identical set of images) keyed 4:4:4 & 4:2:2, and I suppose you can throw in 4:2:0 just for fun.
Does anyone know if any links where one can see such a comparison? Thanks.
