Telecine generates fields, not progressive frames.  So, all telecine
filters (except divtc) need fields to do their work on.

If you've got something like an HDTV stream that is half-height, 60fps,
then you can either try using tinterlace to reassemble it back into
fields, or (more popularly) you can use decimate with the proper
options to remove the duplicates.
