Yep. From that thread sounds like QTGMC need special adjustment for VIVTC.

Problem: the source is a clip with mixed progressive/interlaced frames.
There are purely progressive frames, purely interlaced frames and frames contain both p and i area, like this example.

Problem fix: The jaggies are not caused by QTGMC itself, they are caused by TDeint.
Simply using your QTGMC call alone, without TDeint, results in a jaggie-less video.
The problem is you are wrapping QTGMC in TDeint. I suspect it is caused by the fact that by default QTGMC does not leave the original fields unaltered. TDeint does, so the interpolated fields by QTGMC do not match the original ones that TDeint injects, resulting in jaggies.

I noticed they figured out further scripts to counteract the issue. The hard part i am wondering, if the same can be done in vapoursynth, as avisynth is different.
