It's a bug in the ffmpeg call.
The ',setfield=tff' part belongs to ' -vf crop=696:472:4:2' and the additional '-vf setfield=tff' should not be there.
(interlaced output isn't tested a lot, since I don't use it at all)
Enabling "Filtering->Vapoursynth->Misc->Script->Always use Vapoursynth" might work till I have fixed that.
