How much chroma cleanup to apply?

Post by stevecaps » Wed Jul 29, 2009 8:48 pm

Is there such a thing as "too much" chroma noise reduction? Should I just leave it set at 100% or is there an advantage to leaving some chroma noise in?

In our experience, 100% is fine, so we made it a default. Luminance noise looks much more natural than color noise so leaving some noise in Y and suppressing 100% of it in Cr/Cb is usually a good idea, unless you want to achieve some special effects.

Hope this helps,

Thanks! Just wanted to make sure it wouldn't lead to a loss of subtle color variations. I want to avoid giving everyone a "pancake makeup" look.

100% it is, then!

The most important thing, of course, is to correctly build the noise profile. When the profile is accurate, 100% noise reduction in color channels is fine.
