It would, but it's not a real frame, because line 1,3,5,etc., were captured
1/60th of second off from line 2,4,6,8,etc. See http://www.100fps.com/
for a fairly good layman's guide (although it is PAL-oriented, much of it
applies to NTSC, too, just substitute 30fps where they say 25fps) to just
what happens in a good de-interlacing system. It ain't easy or cheap to
do right.
