[REQ] QSV DeGrain
Hi there, 1st of all thanks for your great work !
Even if the well-known encoding expert (and Hybrid author) Selur does not recommend it, since the latest QSVEnc version - 7.02 - added 3D denoise filter, it would be great to implement some kind of DeGrain in order to achieve some compressibility gains.
Dunno which performs is better in terms of quality:
- http://avisynth.nl/index.php/SMDegrain
- http://avisynth.nl/index.php/RemoveGrainHD
- TemporalDegrainV2
Hope that inspires.
These filters seems to be a combination of many filters, TemporalDegrainV2 and SMDegrain depend on MVTools, and RemoveGrainHD also looks rather compilacted. I think it will be difficult for me to implement by OpenCL in limited time.
As QSVEnc supports reading avs, please use these filters via Avisyth if required.

Well then, the easyest one to "port" shoud be @joelek's denice then: https://github.com/joelek/denice
Anyway some convolution3d "presets" would be also interesting...
OK, here's a couple of discussions @intel 's forums about hw denoising in oneVPL:
- https://community.intel.com/t5/Media-Intel-oneAPI-Video/Intel-Media-SDK-s-denoiser/m-p/1000998
- https://community.intel.com/t5/Media-Intel-oneAPI-Video/VPP-denoise-detail-not-working-on-hardware-1-3/m-p/995371
Hope that helps.
Bump.
Seems that @AhmetCanSolak's aydin has putted - and is still putting - together several denoising algorithms (optimizing, if we understand correctly, for exploiting -nVidia- hardware too):
Hope that inspires !
