VIVTC RGB/YUV44P8 content, where did I go wrong?

[Selur]

Trying to use VIVTC on RGB/YUV444P8 content, reading http://www.vapoursynth.com/doc/plugins/vivtc.html
I came up with:

# adjusting color space from RGB24 to YUV444P8 since VsVIVTC doesn't support RGB24
clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, matrix_s="470bg", range_s="full")

# converting YUV444P8 clip to YUV420P8 for VFM
yv12=core.resize.Bicubic(clip=clip,format=vs.YUV420P8, range_s="full")
# Forcing chroma to False for VFM due to usage of yv12
clip = core.vivtc.VFM(clip=yv12, clip2=clip, order=0, chroma=False)

# converting YUV444P8 clip to YUV420P8 for VDecimate
yv12=core.resize.Bicubic(clip=clip,format=vs.YUV420P8, range_s="full")
# Forcing chroma to False for VDecimate due to usage of yv12
clip = core.vivtc.VDecimate(clip=yv12, clip2=clip, chroma=False)# new fps: 23.976

This does not crash, but it also doesn't remove the combing,...

-> Can someone tell my how this should look like to actually work? It's probably something stupid I'm overlooking or misunderstood.

If you read your link , VFM does not have post processing built in like TFM (pp=blah); you need to apply it afterwards . There is an example in the docs with FrameEval and functools

YUV444P8 is supported, there should be no reason to convert to YUV420P8 at that stage

Ahhh,.. that helped:

clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, matrix_s="470bg", range_s="full")      
yv12=core.resize.Bicubic(clip=clip,format=vs.YUV420P8, range_s="full")
# Forcing chroma to False for VFM
clip = core.vivtc.VFM(clip=yv12, clip2=clip, order=0, mode=4, chroma=False)
deinterlaced_clip = core.eedi3.eedi3(clip, field=1) # or other deinterlacer

def postprocess(n, f, clip, deinterlaced):
   if f.props['_Combed'] > 0:
      return deinterlaced
   else:
      return clip

postprocessed_clip = core.std.FrameEval(clip, functools.partial(postprocess, clip=clip, deinterlaced=deinterlaced_clip), prop_src=clip)
clip = core.vivtc.VDecimate(clip=postprocessed_clip, chroma=True) # new fps: 23.976

does the job.
