MP4 is an abbreviation for Moving Picture Expert Group-4. It is a standard in digital music technology that reduces video file sizes for more efficient transfer of files. This movie format has gained wide acceptance for its small size and high-quality video. It made its entrance in 1998 and has since become one of the leading formats for transmitting video over the Internet. The bit rate of an MP4 is an important quality since it determines the overall quality of the video.
