That would not even be true for non-interlaced-aware
scaling afaict (and I suspect not even for a "simple"
implementation), and it is of course not true for
the interlace-aware scaling that FFmpeg provides.
(The idea is to scale two half-resolution images to
half the resolution of the output image.)
