Very interested in your CUDASynth.

I made a zoomed in crop of CUDA Synth Denoise and Sharpen vs my encoder favorite SMDegrain and LimitedSharpenFasterMod.

Good stuff.
DGDenoise vs SMDegrain(tr = 2, thSAD = 500)
Image
DGDenoise- much more smoothing, like it's a stronger setting than my SMDegrain Medium preset.
Image
SMDegrain- does a good job on the grain and keeps and enhances details.

DGSharpen vs LSFmod(strength = 400)
Image
DGSharpen- The grain pops and the image looks a bit more in focus.
Image
LSFmod- My LSF pic looks like I didn't apply the filter. I really might of made the mistake. :(


DGDenoise + DGSharpen vs SMDegrain and LimitedSharpenFasterMod.
Image
DGDenoise + DGSharpen- Well cleaned of grain, and picture has some sharpening but lost of hair and textile textures.
Image
SMDegrain + LSFmod- Well cleaned of grain without loss of textiles and hair, picture looks clearly sharper as if in better focus.

Very good work here by Mr. DG!
I would rate these better than KNLMeansCL and WarpSharp. That being said, SMDegrain and LSF remain the tools to beat from what I can see.

These cropped screens are from full CRF 22 1080p encodes of the clip.

I tried actually using the DGSharp and unfortunately it just seemed to bring out the dither more than anything else. I think most sharpens have a function to ignore grain and dither as sharping those is sub-optimal in most cases.
