No, it isn't still. There are several scenes in that unfavored sequence,
with low-motion panning and rotation. When watching them frame by frame,
telecine patterns are unnoticeable on some parts and hardly noticeable
on another. -vf spp=6,detc=dr=2 produces very good results (even if it
is wrong, looks like detc is smart enough to ignore blurring ;) ).
Anyway, since detc works this way, I'm happy enough. Thanks for writing
such solid filters! :)

Btw, does "duplicate frame" message after detc or pullup always mean
that it was in original material (it's anime and most likely there is
frame duplication on dvd) or it can be something else?
