The MP4 file format was generalized to ISO Base Media File Format ISO/IEC 14496-12:2004 that defined the general structure for time-based media files. The first version (ISO/IEC 14496-1:2001) of MP4 was a revision of the MPEG-4 Part 1: Systems specification published in 1999.

MP4 specification was developed by Moving Picture Experts Group (MPEG) and was based on the QuickTime format MOV that was published in 2001. Due to the high compression used in MP4, the resultant files are smaller in size with almost all the original quality retained. Similar to most modern container formats, MP4 supports streaming over the internet. MP4 is an international audio-visual coding standard. It is mostly used to store video and audio but can also be used to store subtitles and still images. MP4(short for MPEG-4 Part 14) is a file format based on ISO/IEC 14496-12:2004 that is based on QuickTime File Format but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features.
