phase shifted PAL TIVTC

[Selur]

Do not use TIVTC (= TFM + TDecimate) as a whole, since no decimation is needed.

Using one of the field matchers under "Filtering->Vapoursynth->Frame->Misc" TFM/VFM/ITM should work fine.
The field matcher, will make sure the content is progressive, so no deinterlacing will take place afterwards.
If there is still some combing, add "Filtering->Vapoursynth->Denoiser->QTGMC" (try different input types) or ."Filtering->Vapoursynth->Frame->Misc->Vinverse/Vinverse2" or "Filtering->Vapoursynth->Line->Santiag".
