Er.. Yes, my mistake - of course I meant hard telecine.

Thanks, just what I needed to know.

However, pullup seems to perform much worse than detc and filmdint on
this material, it prints a lot of "skip frame" messages - there are
low-motion sequences up to 15 seconds where it can't drop anything at
all. Is there some solution to get both postprocessing and nicer ivtc
process than with pullup?
