MP4 is short for ‘MPEG-4′. The official file extension for MPEG-4 is .mp4 – hence the shortened name MP4.
MPEG-4 engineering has been designed to offer DVD top quality audio and pictures in an extremely modest document sizing – ideal for playing on portable MP4 players just like the iPod Video.
MP4 is here to stay. The Apple Corporation themselves describes MP4 as “the global multimedia standard, delivering professional-quality audio and picture streams over a wide range of bandwidths, from cell phone to broadband and beyond”. Thy go on to say that “hundreds of researchers around the globe contributed to MPEG-4, which was finalized in 1998 and became an international typical in 2000″.
