RE: Can't run Cnr2 noise reduction - Miranda - 31.01.2022
In the case of the ancient VHS I'm trying to improve, I don't think I need to worry too much about any minor colour shift.
RE: Can't run Cnr2 noise reduction - Selur - 31.01.2022
Yeah, but the Vapoursynth encode seem really 'off' to me.
-> looking into it
RE: Can't run Cnr2 noise reduction - Miranda - 31.01.2022
I wish I had your knowledge!
RE: Can't run Cnr2 noise reduction - Selur - 31.01.2022
Okay, issue seems like there was a 1 frame difference somehow, not a color issue.
-> Do Avisynth and Vapoursynth work for you now?

Avisynth worked fine with Cnr2. I'm running a mClean in Vapoursnyth now.
There are so many filters, and within each filter so many variables. It's hard to know where to begin with VHS clean-up work.
RE: Can't run Cnr2 noise reduction - Selur - 31.01.2022
And you don't have the torchAddon which additionally adds some ml (machine learning) based filters to Vapoursynth.

I'd like to try the add-on - if it isn't too difficult.
RE: Can't run Cnr2 noise reduction - Selur - 31.01.2022
Will have to package and upload it anew (a few things changed).
Also note it:
a. requires a NVIDIA graphic card
b. a 12GB download and 18gb extracted
-> so if you are still interessted I can package it anew and upload it.
Also: Introduced a bug in the Vapoursynth Preview in my dev version, uploaded a new one and send you a link via pm.

Thanks. I'm still working on finding the best method of cleaning the old VHS at SD, then I need to upscale to 1080p.
It's a feature film, so many different scenes with different quality and lighting etc. And it's from a VHS that is from a master tape that was originally shot on uMatic back in 1983. Not an easy task.
RE: Can't run Cnr2 noise reduction - Selur - 31.01.2022
Okay, will package and upload the addOn and send you a link.
Also since you are looking for more options.
Hybrid also allows to:
- change the filter order under "Filtering->Vapoursynth->Misc->Filter Order/Queue"
- let you freely decide which filter to add in which order and multiple times when using "Filtering->Vapoursynth->Misc->Filter Order/Queue->Use Filter Queue"
- has options (which can be enabled under "Filtering->Vapoursynth->Misc->UI") to
- only filter a specific range of frames ('Apply only to')
- only filter a rectangular region of the frame ('Only on region')
- only apply filters on masked 'regions' ('Masked') <- this one is really new and just at the beginning (not many mask options atm.)
- only filter a specific range of frames ('Apply only to')
Since I have to go to bed now I'll send you the link via pm.
Upload should be finished in ~50min.
=> have fun
