text: SMIL (Synchronised Multimedia Integration Language) is an official W3C (World Wide Web Consortium) specification which offers a simple framework for creating rich media presentations from separate elements. Although support for SMIL is still far from perfect, it is one of the useful formats for creating captioned video presentations like Zeldman's Web Essentials keynote speech. \n\nA fairly detailed explanation of how the video was achieved can be found on the 'Skills for Access' site.
