How so ?  Assuming you're actually applying it (all frames), or deint=1 and
the frame is marked as interlaced in ffmpeg parlance:

If you use mode=0  (single rate), either it auto selects the parity, or you
explicitly set it top or bottom

If you use mode =1 (double rate) , it's a non issue because both fields are
retained
