I do it in one pass in the deinterlace section.
As much praise as the QTGMC deinterlacer gets on these forums, I have found that it creates wobbly motions on any level that’s not Very Slow. And even then, there’s still some wobble. It does, for sure, keep more detail than ffmpeg yadif. So I keep using it.
Last week, I tried to run Doine DV in the command line. Turns out it does no deinterlacing. TVAI instead uses the bwdif filter from ffmpeg to do the deinterlacing. Some time I plan to compare QTGMC vs yadif vs bwfif.
