Deoldify Vapoursynth filter

[Selur]

That looks wrong as a prefilter.
I would suggest using something way more aggressive.
(despot is fine, but then I would use one of the denoisers as prefilter)
Remember the main goal of a pre-filter is not to retain details, but to remove details that hinder motion estimation, etc.
Look at your source with YUV split, and you see that usually your chroma doesn't usually hold much detail the chroma created by DeOldify (https://imgsli.com/MjYxMDUz), will not contain more details so using elaborate denoising is probably the wrong (unnecessary time-consuming) approach. First thing I would try is something like Bilaterla (GPU) as prefilter.
Here to show what I mean in code:

Not sure this is useful at all,... or whether something like KNLMeans&Co should be used.

I will add a degrain option in vsdeoldify in the next RC.

Please don't unless you have already tested this intensively, and also don't think about adding another xy option array for this. (I will not add another option array in Hybrid.)
