First off QT file format is what is known as a wrapper or container just 
as AVI is wrapper or container.  It can contain different media.  I know 
because I worked on QT file formats, know Apples use of pcode within 
these formats so I could convert from their format to another.  MPEG 
standards for Motion Picture Experts Group who developed MPEG-1, MPEG-2 
and MPEG-4.  It is a consortium and yes Apple contributed to it.  MPEG-4 
is also known as h.264 which grew out of h.263.  The latter is more open 
source so companies like Divx, Adobe, and the open source Xvid use it.  
Version 7 of Flash and earlier uses h.263. Adobe now uses On2 
technologies compression.  Apple's big contribution to AV from my 
recolletion was Firewire.
