Shirt problem in this video

Hello I have been trying for atleast 3 days to find settings that would fix this thing but I can't, look at the shirt and the paperr thing.I want to remove those lines

Back to that clip in another filter step,...
Bad chroma handling, sharpening and resizing.
Don't think there is a really good way for this.

About the horizontal lines in the blue shirt, try some AntiAliasing + sharpening, like:
Santiag followed by CAS (!adjust FilterOrder!):

clip = antiAliasing.santiag(clip, strh=3, strv=3, type="sangnom", aa=64, opencl=True)

Out of curiosity, here's what happens if one first applies the Santiag as suggested and then feeds the output through a diffusion resizer (here SeedVR2).

(no there is nothing comparable for it in Hybrid)

Thanks so much for the help, I have been trying as much as I could to fix that one but can't. Is it ok if I give you another one with simmilar problems? 

This one has simmilar problems with the Halos in the shirt.

Also I think I am dump cause I don't understand what santiag is

[Selur]

Santiag is an anti aliasing filter which is based in a deinterlacer, which makes it capable to handle such artifacts.

Will look at the other sample later, when I'm back home.

Could you tell me how to use it when you get home? I have tried searching about it but so far got nothing.

Filtering->Vapoursynth->Line->Anti-Aliasing->Santiag
And then adjust the settings.

Okay, that is a different problem (also caused by oversharpening and reencoding oversharpened content; maybe capured with some additional sharpener turned to max).
Hmmm,.. applying BindDehalo3+Santiag

clip = dehalo.BlindDeHalo3(clip, strength=150, interlaced=False)
# applying anti aliasing using santiag
clip = antiAliasing.santiag(clip, strh=3, strv=3, type="sangnom", aa=64, opencl=True)

is way blurrier than the original, but more pleasant to the eyes imho.
After that maybe use Detailsharp and/or CAS to sharpen it a bit,..
