I am only concerned with the default controls that appear when the
@controls attribute is used. I believe we can mandate for this
situation that the captions should always stay above the default
controls. What a Web developer does with custom controls is out of our
control anyway and they would need to make sure that if they provide
captions it will still work for their audience.

Maybe we do need to prescribe more specific recommendations on the
@control. Maybe that the controls should overlap only the bottom part
of the video up to a certain percentage? This is how it is currently
implemented by all browsers, so shouldn't be a problem.

I do not believe in moving the controls to different locations around
the video container space - that would be confusing to people. Moving
captions up will only slightly disassociate the captions from where
they were originally placed - in basically all cases not enough to
change the meaning.
