Cleaning 3840x2160 mp4 clips

[Al74]

Hello, Selur, and all forum members,
Recently, I started to create a short private movie from my clips. The files were recorded in CineD profiles. I applied a certain LUT and saturation correction and rendered the file. Looking at it up close, you can see a few blocks, some moving noise, etc. The original file also looks similar. And here is my question: Which filter(s) would you use to clean up or improve the problems? I have tried the Deblock filter and the QTGMC one; it helps, but I expected more.
What filters would you recommend? 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?
LUTs aside, I used to record with a natural profile, so I am generally seeking help overcoming these specific problems and would be grateful for some comments and tips. All these clips were shot with either the Lumix GX9 or GX80.
Thanks in advance for any help.
Below I give WeTransfer with the files. Two clips are original mp4 files and two files are the files after applying LUTs and increasing saturation and rendered to FFV1 files.

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.

Dear Selur,
Thank you very much for your help. I shall use your settings and compare them with my attempts. I also tried YAHR and it helped, I forgot to mention it. As far as the corrections stages are concerned, well, I also try to do it as you suggested and also look for info about the topic.
Best

" 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.

Yes, I also added YAHR.
vsGLSLCAS ("Filtering->Vapoursynth->Sharpen->CAS (GLSL)") is GLSL based CAS filter.

Why did you change colours space in these tests?

All color space changes in the script should be commented with an explanation why Hybrid added them. I did not actively change the color space anywhere, all changes were added automatically.

At what stage do you add sharpening? At the end?

Depends on the source, but usually add the sharpening after denoising etc. and before dehalo, subtitle adding, letterbox,...

No clue whether you added something or just made one large quote,...
Since the whole thing is inside 'Selur wrote' I suspect you did not add anything.

=> please do not use full quotes of posts,...

Selur,
Sorry, I have deleted it there.
Here is the question I uploaded:
How to set presets for different filter orders so as not to start from scratch every time? Suppose I have a few useful procedures and would like to load different settings depending on the files I would like to denoise?

[Selur]

Save different defaults. FilterOrder atm. isn't part of the Filter Profiles.
=> Correction it is,.... then simply save the filter settings.
