I tested some denoising filters, scripts the last weeks and finally came across DGDenoise which I have to admit is what I was looking for
![Thanks :hat:](./images/smilies/icon_hattip.gif)
I played with different setting for strength and searchw in combination with DGSharpen afterwards with great results. Picture quality gets better and also compressibilty.
Now my question: What does parameter cstrength do?
I understand that is supposed to denoise chroma level, but regardless which values I try I see no difference.
My normal procedure is to load my Avisnth script into AVSPmod to tweak and preview the settings.
My source files are blurays which I down-resize to 1280 and encode with x264@CRF=20.
Unfortunately I only have a GT730 card I bought a few years ago in order to use DGDecNV which is really slow.
Is my graphic to weak for this kind of operation or are my source files simply not affected?
Does someone has a hint which parts of the picture are affected by cstrength?
Doesn't matter if I set value 0.10 or 1.00. Encoded picture look the same for my old eyes
