There are many camcorders that make the 30 fps at 640×480 claim.
Many of these "cameracorders" have a slow bus between the cache memory to the recording card to allow for VGA/30 fps. If the designers had chosen MPEG-4 instead of Quicktime, there would probably have been no problem in filming in VGA resolution/30 fps until the cows go home.
