Easiest is to say, that while the 1.0 branch is in 'beta' the doc and wiki will be outdated or have a chance to be incorrect. It's a beta for a reason, a quick release to find problems, not to have a complete finished and documented release :P.
Then again, there are a lot of plugins and products around here that never leave the beta phase so. mweh . |

The update log mentions "Improved de-noising quality around image edge." Maybe that's the reason? Update: I have made another test of v1.0.0-beta.1 on vapoursynth just now. Yes, the default value of "wmode" is 1 for both version, but in v0.7.7, it indicates "Welsch weighting function", while in v1.0.0-beta.1, it indicates "Modified Bisquare weighting function", so what I have suggested you before to set it to 0 for v1.0.0-beta.1 is to return to use "Welsch weighting function". I'm sorry for my poor English expression. I'm not a native English speaker. Last edited by WolframRhodium; 14th December 2016 at 11:01. |

Different noise treatment should be somewhere else. Khanattila, can you please tell us what is under the hood?

v1.0.0 beta1 wmode=1 (my fault) -> Bisquare v1.0.0 beta2 wmode=0 -> Welsch

just in case if anyone's curious about the mathematic definition of each weighting function... |

I find strange stains at the border when using v1.0.0-beta.2, especially when "a" is large.
examples: http://screenshotcomparison.com/comparison/193750 Just look at the top border of the filtered image. There are also some stains at the left/right border, but is nearly invisible. The problems happens on both "channels". Last edited by WolframRhodium; 14th December 2016 at 13:42. |

How is possible to denoise a normal DGDecNV output on both Y and UV? If I left auto, it uses Y only, if I try YUV it tells me
error: KNLMeansCL: 'channels = YUV' require a YV24 pixel format!

a) Processes each channel independently. b) Process "Y" and "UV" separately. c) Converting to RGB, processing, and them back to YUV. d) Other more elaborate methods.
