Just a comment on motion-est, though I don't think it's very relevant
(IMO trying to improve mpegvideo is mostly a waste of time).

motion-est is horribly inefficient.  It can be made way faster.
However, it is stuck in a LOCAL MINIMA.  Any step towards making it
faster will inherently make it slower first, because making it faster
requires some larger-scale design changes.

Michael, your problem seems to be in general that you only work by
gradient descent; maybe you should try simulated annealing?
Random-restart gradient descent?
