Alas... if I had waited a mere few minutes I might have noticed your answer
before I replied to him as well.

This doubling of frames is what I wasn't understanding from the
documentation. In rendering a little test and viewing non-interlaced, i.e.
regular mpeg, I came to the conclusion there wouldn't need to be twice as
many frames to look just like animation without field rendering. Or rather
that television might interlace in a frame by frame stepping which doesn't
actually merge the pairs into a single frame again. That is, except by
persistence of vision effect.

To clarify further, I guess I need to understand that the even/odd frames
are combined during television conversion, and so need a double rate to
equal uncombined frames? Only wondering out of curiosity in my case, not out
of necessity like Rafal.  :-)  I just didn't think the process merged
frames. Seems impossible to locate information about this being
demonstrated.
