Comment (by elenril):

 Okay, I see the problem in the handling of the `-top` option. The thing is
 also that it is badly named, underdocumented, and entirely redundant with
 the `setfield` filter - transcoding your video with `-vf setfield=tff`
 produces correctly-looking output. I'm thinking the option should be
 removed and everyone should switch to using the filter.
