Cleaning 3840x2160 mp4 clips

[Al74]

Here's an example of what:

• DPIR deblocking would do to P10702: https://imgsli.com/MjY4Nzky
  
• BasicVSR++: https://imgsli.com/MjY4Nzkz
  

Those filters are really slow (we are talking multiple minutes per frame) on 4k content; to be frank, I'm even surprised it worked on my hardware on 4k content. So they are not really a suggestion, more a blind-test.

Looking at it up close, you can see a few blocks, some moving noise, etc.

If you zoom into most sources, there is always something one could change.
=> Can you be more specific on what you want to change/improve?

I have yet to sharpen the file; maybe it would be a good idea to apply LUT, add saturation, sharpen, and then denoise/deblock etc? Is that a good approach?

Personally, I would apply LUTs in such a case at the end, to compensate unexpected color changes due to other filters with it, but it should not really matter.

Some filtering, without knowing what I aim for:

• P10702 - MNLMeansCL + PlaceboDeband + CAS.: https://imgsli.com/MjY4ODAx (script: https://pastebin.com/F5KUz1vj)
  
• P10702 - DeBlock_QED + CAS + SMDegrain  + DeHalo_alpha + YAHR: https://imgsli.com/MjY4ODc0 (script: https://pastebin.com/jFAyBiu6)

Ps.: moved thread to 'Small Talk' since it's not really problem with or bug of Hybrid.

" P10702 - MNLMeansCL + PlaceboDeband + CAS.: https://imgsli.com/MjY4ODAx (script: https://pastebin.com/F5KUz1vj) " - you also added YAHR, yes? And what about vsGLSLCAS ? Is it CAS sharpenning filter?
Why did you change colours space in these tests?
At what stage do you add sharpening? At the end? I am trying to figure out appropriate procedure to deal with some corrections. And you are right probably, LUT maybe later on or I just use some colour/saturation corrections using my own settings.
