if the material is completely soft-telecined, you should not be using
pullup, since it will just waste time, and either do nothing or
introduce errors!

if the material is hard-telecined whatsoever, you CANNOT apply
postprocessing to it directly or you will ruin the separation between
the fields by blurring them together. so always use -vf pullup,spp,...

detc most definitely does not pass the quantization info through, so
postproc filters will not work correctly after it. filmdint might; i
don't know. ivtc does not. pullup does.
