Quicktime plugin missing when trying to play movies

I don’t understand why Apple does not offer the ability to record in .mp4 format on iPad and iPhone Cameras. Both devices can play .mp4 movies (H264 codec) so I it makes no sense that they restrict their cameras in this manner. I record over a thousand movies per year for my website and they are all in .mov format for this reason, I think its time of Apple to let go of .mov
