    Code:
    -vf yadif=mode=0:parity=bff
    will select the bottom fields, discard the original top fields, but interpolate a new top field, giving you a full frame size. e.g. 720x480 for "NTSC" or 720x576 for "PAL"

    Or did you want just the "half height" original bottom fields ? 720x240 for "NTSC" or 720x288 for "PAL" ?
