I can understand why you might tweak the knob toward lower resolution,
particularly if you are running a transcoder.  In the other direction,
maybe the perceived gain in overall quality is improved more by having
more pixels than by eking the last bits of quality performance at a
lower resolution.

I'm wondering at why you would want to specialize the interface
further just because the use cases don't all line up.  Sometimes the
general thing is easier to define, build and test than the more
specialized thing.
