Deoldify Vapoursynth filter

[Selur]

Hmm,...

clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="709", range_in_s="full", range_s="limited")
...
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="709", range_in_s="limited", range_s="full")

and

clip = core.std.Levels(clip=clip, min_in=0, max_in=255, min_out=16, max_out=235)
...
clip = core.std.Levels(clip=clip, min_in=16, max_in=235, min_out=0, max_out=255)

do totally different things to the histogram.

What do you think, it is a Vapoursynth problem ?

I doubt it.
