[HELP] Fragments disappear in hand-drawn animation

[Selur]

And where to find DPIR deblocking?

DPIR and some other filters require a special addon, but that is only supported if an NVIDIA card is present, so you can't use it.

in the case of sample 5, which is better

Can't handle sample 5 atm. in Hybrid since the Vapoursynth Preview stumbles over some meta data.
-> working on that.

What settings should there be for filters?

Not going through all the filters and trying to explain each option.
For example for mClean I would use SAD threshold 900 and ReNoise 0.

# applying deblocking using DeBlock QED
clip = havsfunc.Deblock_QED(clip, quant1=40)
# denoising using mClean
clip = G41Fun.mClean(clip=clip, thSAD=900, rn=0)
# sharpening using AWarpSharp2
clip = core.warp.AWarpSharp2(clip=clip, blur=2, depth=20)
clip = havsfunc.EdgeCleaner(c=clip)

seems like a good idea to start.

Will look at it some more in a few hours, since I'll be offline for a while.
