unrelated to your problem, but these options to pp are very bad.
hb/vb is not good deblocking; you want to use "ac" instead, or the
spp, pp7, or fspp filter instead. however it looks like your content
is interlaced (since you're deinterlacing it, albeit very badly) in
which case postprocessing won't work well anyway.

if you don't want the final video to be interlaced, i would recommend
just throwing away the bottom field (-vf field=0) or (if it's
telecined) using an appropriate inverse telecine setup.
