No subject

can be done in QT that could not be transcoded in MPEG-4 (maybe this
will be available in the next release of ENST product). 
Indeed, the graphics part of  MPEG-4 has to be seen as the *java
bytecode* for transmitting graphical animation in an interoperable way.
Other languages, like SMIL, X3D, or high level languages that are closer
to the author intends can be compiled in MPEG-4 for transmission. At the
player side, all you need is then an MPEG-4 player.
Kind regards,
