thanks for the quick reply. so does pulldown imply interlaced content? 
clearly the source material is 23.976, since i can see the 3/2 pattern 
when stepping through it. so i guess i thought that any framerate 
conversion from 23.976 to 29.97 or 59.94 would involve pulldown.

i'll search thru the archives and see if there's any info about the 
vf_tinterlace trick. i wonder if mencoder would just do the right thing 
if i just give -ofps 24000/1001? it is spitting out "Skipping frame" 
all the time, but i thought that was the pullup filter working. on 
thinking about your reply it does seem like a "trivial" problem to do 
this framerate conversion since you really only need to discard whole 
frames which are dups.

thanks,

rob
