    As you can see with this attached GIF, it's blending frames together, it's almost like motion blur, or SVPFlow kind of thing.
    I want to use QTGMC with absolutely no filtering. No denoising, No SVPFlow sort of thing, just deinterlace.

    Code:
    clip = core.d2v.Source(r"E:\American Dad Stuff\SD\S01\S01E01\S01E01.d2v")
    clip = QTGMC(clip, Preset="Placebo", TFF=True)
    clip = core.vivtc.VDecimate(clip, cycle=5)
    clip = clip[::2]
    The original clip is 24000/1001 Progressive with a Scan Type of 2:3 Pulldown, but when using DGIndex, the resulting .d2v file is still interlaced (when ignoring pulldown flags)

    Does anyone have any ideas?

  2. That's a very common problem with QTGMC.

    Nothing that can be done about it for a better deinterlace?

  4. QTGMC know to have problems especially with this type of animation

    But what is the reason for deinterlacing in the first place ? Usually animation is not interlaced

    Can you get a clean IVTC ? Or just bad source ?

  5. QTGMC it's a very good tool but it's not the best tool for everything. Here I use yadifmod2() for simple things that doesn't require the power of QTGMC.
    As poisondeathray said, animation in general are not interlaced unless it's a bad source.

    You have to experiment with the "sourcematch" and "lossless" parameters in QTGMC. An edgemask would also help.

    Update: You could in fact get a clean IVTC with this source (final stream being fully Progressive, with no trickery). What needed to be done is index via DGIndex and do not honor RFF when loading with core.d2v.Source. Then AssumeFPS to 24000/1001 because core.d2v.Source will incorrectly load it as NTSC (or PAL), even if all frames are progressive using Software Pulldown.

    I now have a release called MPGG that deals with stuff like this for you automatically, see https://github.com/rlaphoenix/mpgg
