... frame 6167. I tried to clean it in the past, but didn't get very positive feedback. It's a really difficult frame, because of the amount of grain.
With Super Resolution being a temporal process, using temporal noise reducers will directly work against the SR effect. One must use spacial noise reduction, but those tend to smear over everything, even those having withholding parameters (edge-preserving smoothers).
I don't know if there is an Avisynth equivalent to this, but I've found a paint program's JPEG artifact removal to be an amazing noise reducer by targeting "out of place pixels" that happens with such things as compression and random noise. If a pixel is in keeping with it's surroundings, it isn't processed. As a result, the noise is reduced (strength settings: low, normal, high, maximum) but the detail is not ..
