Can you suggest a good way to remove chroma noise? The scenes are pretty static. I'm new to avisynth but I tried Cnr2. It did help a little but I have no idea how to tweak it for better results or should I even use it. I will upload a clip. The clip is rendered WITHOUT Cnr2. It's a progressive file.
Code:dehalo_alpha(rx=2, ry=2) TemporalDegrain(SAD1=200, SAD2=150, sigma=8) Cnr2("oxx",8,14,191,75,255,20,255,false) Sharpen(0.2) nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1280, fheight=720) Sharpen(0.2) nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1920, fheight=1080) Sharpen(0.2)

Lordsmurf, thank you! This solved it!
You should denoise before you upscale.
Yes, I did that. Btw. Jagabo, I wanted to ask, why do upscaling in two phases? I read that it gives better results and if that is so, how do you calculate the first phase resolution? I mean, for example I want to upscale from 720x576 to 1280x720, so that means to first upscale to something in between of those two resolutions and then to the final resolution?
When upscaling SD to 1080p I use nnedi3 to upscale about half way, sharpen a bit, then the other half, and sharpen a bit again. But for 720x576 to 960x720 I would just use one upscale.
