Hello Steve,

The double-composite?

I cheated.  I overlaid the two still frames as layers in photoshop,
then screened the top layer.  Added the identifying text as a text
layer to the top-most layer.

Ultimately I'll write an ImageMagick or GD-based application to
composite these things together, I just haven't gotten around to it
yet - so many projects, so many [more] demands.  ;-)
