WF_BlurYUV is a Blur algorithm using YUV channels, as seen on some old video color correctors. This effect can be used to smooth skin tones and get better consistencies on solid colours by blurring the U and V parameters and keeping the luminance details by keeping the Y to zero. It can also generate interesting glowing and olf film effects by blurring only the Y channel.allows to blur channels independently. It can be useful to create old video effect or to give some halos effects in the highlights.

Y, U, V sliders blur their own channel. They can be Linked.

Effect mix slider will adjust the percentage between the original and the picture after effect.
