For all practical purposes, 4:4:4 means RGB, that is, everything that comes out of the camera is recorded at full bandwidth, which is what is needed for cinema quality greenscreen work.
I know that 4:4:4 has to do with color sampling and it's the highest and best quality over 4:2:2 and 3:1:1, etc. But I don't really understand what this is referring to and it means. Can someone please help me understand this type of information?
The terminology has been totally FUBAR-ed over the 25 years or so since it was first implemented, to the point that it has become essentially meaningless. Everybody has their own idea what the various numbers mean, which is not necessarily what other people think they mean.
The Wikipedia article mentioned is a mixture of sound information and arrant nonsense, but it appears that original author is so sure he knows what he is talking about that he won't tolerate any changes. Which is par for the course with Wikipedia.
