Deinterlacing with QTGMC merges/blends frames together [vapoursynth]

[PRAGMA]

[Attachment 49492 - Click to enlarge]

As you can see with this attached GIF, its blending frames together, its 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.

The script im using right now is:
havsfunc = importlib.machinery.SourceFileLoader('havsfunc', r"C:\[ENCODING]\StaxRip\2.0.0.0\Apps\Plugins\VS\Scripts\havsfunc.py").loa d_module()
clip = core.d2v.Source(r"E:\American Dad Stuff\SD\S01\S01E01\S01E01.d2v")
clip = havsfunc.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?

That's a very common problem with QTGMC.

That's a very common problem with QTGMC.

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

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 ?

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.
