help improve the radiohead's "fake plastic trees" music video

[rrats]

this is the best version i could find. radiohead's videos from "the bends" era tend to be the least good looking ones when it comes to video quality and this video is probably the worst looking one. is there a way to save any of it?

It may help if you were to indicate what you consider is 'wrong' with the sample.

How does this compare to the version on YT ?


I do note that the YT version is 25 fps whereas you appear to have a NTSC dvd source. However, the official dvd source, according to Amazon, is PAL.

This should help it some.

source = last
dehalo_alpha(rx=1.1, ry=1.1, darkstr=0, lowsens=0, highsens=100, ss=1.0)
hqdering(smoother=deen("c3d",1,3,9,2))
MergeChroma(last, source)
source2 = last
santiag(strv=0, nns=4, nsize=5)
MergeChroma(last, source2)
ChromaShiftSP(x=-1.00, y=0.00)
mergechroma(awarpsharp2(depth=3, blur=1, type=1))
LimitedSharpenFaster(ss_x=1.00, ss_y=1.00, strength=4, overshoot=0, undershoot=0, soft=0, edgemode=0)

blending (also present on youtube, not present on some other clips from the dvd), the sharpening(?) halos

never noticed the off looking chroma. really does look better, thanks

If scene by scene filtering is an option using Vapoursynth and BasicVSR++ might be an option for some scenes:

https://imgsli.com/MTQ4NDU5
but the same settings will cause havok on others:
https://imgsli.com/MTQ4NDYw
DPIR (deblock) works better on some:

so using ai based filters might be worth a try. I agree that some additional dehalo and chroma handling and some masking to lessen the effects of ai filters might be a good idea.
Attached for the fun of it a clip filtered by:
