"Unlike claimed audio improvements claimed video improvements can be captured by cameras, know what I mean? "

Can they, and just what are you saying about audio improvements? I accept that a camera can't capture an audio improvement but other things can.

Let's draw a distinction between "claimed improvement" which was your term, and "improvement". An improvement for the purposes of this discussion is one which can be shown to exist with proof of some kind, whether it be a measurable result of photos demonstrating the change, or whatever. No one really argues about improvements.

On the other hand, everyone argues about "claimed improvements", those improvements for which no proof other than a user's report of their sensory experience is offered. Are you saying that such things don't exist for video performance because a camera can capture everything? Even photographs have a limit of resolution and certain sorts of change won't show up in photographs. If it's digital, does the change involve gradations in colour that require a greater palette than the digital media offers? If it's 'analog' photograpy, does the grain structure of the film obscure the true level of sharpness and detail? I think it will take a little bit more than your one liner to convince me that photographs can resolve any argument about video detail.

"Claimed improvements" fall into 2 groups: those improvements which are real but for which no satisfactory proof has yet to be offered, and those which aren't real and arise from errors, confusion, etc on the part of the claimants. You can't demonstrate scientifically that all "claimed improvements" fall into the second of those groups and there's usually no way to determine whether a particular "claimed improvement" falls into the first or the second group. The only way the arguments about most "claimed improvements" ever get to be resolved to everyone's satisfaction is when a proof is found and they get moved from the "claimed improvement" bundle to the "improvement" bundle.

I admire your optimism about "claimed video improvements" but I require a lot more in the way of proof before I'll accept that statement. I guess that indicates that I don't know what you mean.
