IIRC, this was not only tried several years ago, but patented by MS (the
wavelet approach). This may not be the best approach, however, because
these are lossy techniques applied to a lossless coding problem. You
can't just throw away bits of your motion vectors like you can your
residual data, because even a small change can introduce a large amount
of error (consider a checkerboard or striped pattern).
