  Even in NTSC there is 30fps content but it is more rare.  Regardless
your point is a bit silly, the input is really interlaced, you just
happen to know that consecutive fields are from the same point in time,
but you don't know if the chroma hasn't been filtered differently
afterwords, so just using this knowledge on capture is never correct.
