Is there a potential problem if the source video is progressive?

I think the interlaced flag will toggle back and forth at each frame.
Rather than merely refer to the current frame, would it be better to
re-interlace it by copying both of its fields to a new buffer and
marking it as interlaced? Not only would the flag be correct but
also the colour space would now be interlaced to.
