Help with Futurama Telecine

[Selur]

I tried porting the FieldMatch-function:

import vapoursynth as vs
core = vs.core
import qtgmc

def FieldMatch(c: vs.VideoNode) -> vs.VideoNode:
    pp = core.std.DuplicateFrames(c, frames=[0])
    cc = c
    nn = core.std.DeleteFrames(c, frames=[0])

    # Separate fields
    p2 = core.std.SeparateFields(pp)
    c2 = core.std.SeparateFields(cc)
    n2 = core.std.SeparateFields(nn)

    # Create field match candidates
    pc = core.std.DoubleWeave(core.std.Interleave([p2[::2], c2[1::2]])).std.SelectEvery(2, 0)
    cp = core.std.DoubleWeave(core.std.Interleave([c2[::2], p2[1::2]])).std.SelectEvery(2, 0)
    cn = core.std.DoubleWeave(core.std.Interleave([c2[::2], n2[1::2]])).std.SelectEvery(2, 0)
    nc = core.std.DoubleWeave(core.std.Interleave([n2[::2], c2[1::2]])).std.SelectEvery(2, 0)

    deint = qtgmc.QTGMC(cc, Preset="Fast").std.SelectEvery(2, 0)

    # List of all candidates in priority order
    candidates = [cc, nn, cn, nc, pp, cp, pc, deint]

    # Precompute IsCombed for each clip
    combed_flags = [core.tdm.IsCombed(clip, cthresh=12, chroma=True, blockx=16, blocky=32) for clip in candidates]

    def select_frame(n, f):
        for i in range(len(combed_flags) - 1):  # skip deint until end
            if not f[i].props._Combed:
                return candidates[i]
        return candidates[-1]  # fallback to deint if all are combed

    return core.std.FrameEval(cc, eval=lambda n: select_frame(n, [cf.get_frame(n) for cf in combed_flags]))

and used:

# setting color matrix to 470bg.

# Making sure content is preceived as frame based

# set output frame rate to 23.976fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=24000, fpsden=1001)
# output
clip.set_output()

but one still ends up with broken frames:



my previous try:

# removing grain using SMDegrain
clip = smdegrain.SMDegrain(input=clip, tr=3, thSADC=2400, interlaced=True, opencl=True, device=-1, tff=False)
clip2clip = clip
clip2clip = qtgmc.QTGMC(Input=clip2clip, Preset="fast", opencl=True, TFF=False, FPSDivisor=2)
# Deinterlacing using TIVTC
clip = core.tivtc.TFM(clip=clip, mode=5, blockx=64, blocky=64, MI=64, clip2=clip2clip)
clip = core.tivtc.TDecimate(clip=clip, mode=7, rate=23.9760, dupThresh=0.04, vidThresh=3.50, sceneThresh=15.00, blockx=16, blocky=16)# new fps: 23.976
# Making sure content is preceived as frame based
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
# denoising using mClean
clip = denoise.mClean(clip=clip)

seems to perform better here (and can be directly set in Hybrid)
