I don't know what the state of the art is WRT movies.  But an area that 
interests me is something I would call "de-panning'.  Many dramatic movies 
show moving actors against a basically static background. But the camera is 
constantly panning at a very slow rate. With high resolution, the edge bits 
are changing rapidly with very little value added to the image.  Two 
solutions come to mind:

· Perhaps the edges could be "fuzzed" to a lower resolution
· The edges could be updated at a lower rate, say five times a second 
instead of 24 times a second.

Are either of those (or other) techniques currently used?

I think the people sho wrote the colorizing programs of a few years ago 
could make a big contribution here, I suspect they were able to distinguish 
between active and passive area in the image.
