Not only thay, pp=md (or any deinterlacer) after pullup is total
nonsense. It destroys the whole benefit of inverse telecine by
clobbering the field pullup worked so hard to match...

If the content is mixed telecine and interlaced video, use -vf
filmdint. Otherwise choose between pullup and a deinterlacer according
to your content.
