Can't one use estimations based on the fact we are processing a video?
i.e.  do the full processing in the first round, than use these values
as the initial values for the next round, or maybe even as the final
values (after applying mc), saving precious time?
Also, can't one make the process parallel, so that one could get a
nice small swarm of computers, each processing one frame for an hour,
and if we have 1000 of them, it is about 3.6 seconds/frame, which is
not that bad if one wish to get high quality.

Sweet.
