for your point 1. QTGMC is not the greatest option as I noticed Progressive upscaling in TVAI is not as good as interlaced. read more here.
for your second point, I did not say ProRes is bad, I said it is bad/worse in TVAI.
i used both ProRes and H.265 in TVAI only… and H.265 provided a better quality on interlaced material. facts don’t lie, even if it doesn’t make sense… the field practice prevails…
