I completely disabled the gauss-filter. Now the sharpness is at least
the same as the old yuvdenoise.

Maybe I was wrong with "artifact" word; it's better to say chroma
"ghosting" in motion scenes. With the 1.6.3 yuvdenoise, the chroma is
quite different from the original but it does not suffer so much of
ghosting. Always in the older, the luma in motion scenes was somewhat
blurred.
With the cvs yuvdenoise, the luma is very sharp (quite the same as the
original) but the chroma is ghosted... So, I combined the new luma and
the old chroma (with a simple perl script) and I think it is the best
quality. I sent you some examples by email.

Many thanks,
