Is the 30fps content telecine or just interlaced? You can check with
mplayer -fps 1. If you see a pattern of progressive and interlaced
frames like p,p,p,i,i p,p,p,i,i etc, that's the usual effect of 3:2
pulldown. Other patterns might be workable, but the pattern above is the
most common.

If so, the correct way to deal with it is to use either softpulldown or
pullup. Pullup, however, doesn't always work right with -ofps, so
softpulldown is my method of choice.

-vf softpulldown,ivtc=1 -ofps 23.976
