(First step you have to do is to ensure that your video
is interlaced and not telecined, if it is telecined and
you use a de-interlacer, the video gets permanently
damaged, you cannot undo the de-interlacing.)
yadif is the recommended de-interlace filter, there is
now also a port of Donald Graft's kernel deinterlacer,
it should be both slower and lower quality than yadif
but your mileage may vary.
There is no inverse telecine filter so far for FFmpeg,
if your telecined material is perfect (not badly cut),
you can try to use several MPlayer filters that can
be used from inside ffmpeg.
