Lack of relevant explanation and details will guarantee that you are ignored. Tough love!
Sorry, I was a bit in a hurry.

I am talking about this part of SMDegrain.avsi:

I am a script noob and totally helpless to recreate such procedures to adopt DGDenoise :|

OK, got it. I'll try to find some time to see what is feasible here.

Oh a build for accessible.

I will love to play with it, when the weather gets colder here in north europe.

CUDASynth 0.3:

http://rationalqm.us/misc/CUDASynth_0.3.rar

Make your DGI files with DGIndexNV 2053.0.0.179.
Hello. There's been new releases since DGIndexNV 2053.0.0.179 and I wonder whether 0.3 is compatible ?

And ... perhaps even maybe a CUDASynth v1.0 release say in 2020 ?

edit: I unfortunately muddied the waters over at https://forum.videohelp.com/threads/393 ... ost2565866 ... if you wished to stick your oar in to correct me, that's up to you.
PS great work all round, mate.

0.3 should work with the current DGIndexNV. If there is a problem please advise.

Thanks for the kind words. I'll pop in over there and see what's cooking.

Tashie is recovering in hospital after small accident. She will be disappointed to hear your reply, hydra3333. She was thirsting for you. I send you all best Happy Christmas greetings from Tashie and myself, and I promise you an EPIC 2020. Moose and squirrel will finally meet their match. Bwahahahaha!

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.
