Blur isn't good, but I think you over-state it. With deinterlacers, I
use pp=lb because it's the only one that doesn't produce
terrible-looking output. pp=md looks bad on most material, and
absolutely terrible on high-contrast material like animation, on-screen
I guess I should go try this on some animation to see what artifacts
I can pick-out...

Hmm. I don't understand why they would be 2.5X as large. Anyhow,
wouldn't adding -vf ivtc take care of that?

Well, it's just that I would have thought that -vf field would have done
a bit more to improve the quality...
