IMHO that's horrible compared to normal captions. It is always moving, 
which means you can't read it as fast as normal captions, plus it's 
continually distracting from the image.

Good captions should be so low-overheard for the viewer that the viewer 
can entirely forget that he's reading captions in the first place. You 
simply can't get that effect with rollup captions.
