Whenever I try my favourite SMDegrain filter in Vapoursynth, it crashs. Currently I'm testing Hybrid 2023.03.17.1 (Win64). Even with latest smdegrain.py from github. The last version it worked was for me 2022.05.04.1. Doesn't matter video source.

Other Vapoursynth filters works.

Hint: When I try preview in compare mode, it produces this failure:

If I comment out loading RemoveGrainVS.dll in preview source, it works.
But I don't know how to similarly fix encode .vpy script

Thank you.

Looking at the VapourSynth Script Hybrid only loads Removegrain once.
So it should only be there if there is a global VapourSynth installation which autoloads RemoveGrain.
Sadly, unlike Avisynth, VapourSynth has no option to clear any outside loaded files.
=> If you got a global VapourSynth version installed, deinstall it.

Correction:

Code:
C:/Program Files/Hybrid/64bit/Vapoursynth/vapoursynth64/coreplugins/RemoveGrainVS.dll

->deinstall Hybrid completely and reinstall it.

That folder should only contain 'AvsCompat.dll' nothing else.
The installer only puts 'AvsCompat.dll' there.

My big apologize, now I will remember fresh install is needed. Thank you very much for quick and correct solution.

Ha! I've had the same problem for a while through multiple Hybrid versions and kept thinking the next version would magically fix it. The Avisynth version of SMDegrain worked, which I think is slower but it's fine, except 4k encoding becomes terribly slow.

Finally searched this and other forums Hybrid is on for a fix, and this thread showed up.

Glad to have SMDegrain Vapoursynth version working again. SMDegrain and Hybrid are impressive. Thank you.

there are many pixels in a frame of UHD content to process if the video source is SD or HD. then it’s better to upscale the SD to HD with different filters, or HD and fix it with filters. then clean HD do a regular upscaling to UHD.
