Deoldify Vapoursynth filter

[Selur]

Sorry, to say this, but the bitrate is way too low or my taste given the source.
Ideally, the during digitalization a lossless file should have been created.
Maybe first cleaning up the source, creating an intermediate file and trying to colorize that is a better approach. (doing everything in one job will take ages)
Also, I would probably not use Deolidfy on the whole clip, autowhite and some denoising seem not that bad:

also try with adding:

import muvsfunc
# requires colorformat YUV420P8
core.std.LoadPlugin(path="%FILTERPATH%/Support/libmedian.dll")
clip = muvsfunc.Cdeblend(input=clip,omode=2,xr=4,yr=4)

in a custom section.
