Description The MP4 files (MPEG-4 part 14 files) are the multimedia files which are used with multiple stations and video players simultaneously, they can store not only digital audio streams and digital video but other suitable amounts of data like subtitle tracks. MP4 video format is an extremely common file format due to its very own container format and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP as well. It is also a popular file format for streaming over the Internet. For instance, YouTube videos have MP4 extension.
Technical details The technical details of MP4 files differ in great aspect and are unique as well, first released in 2001 under ISO/IEX 14496-1:2001 standards, it uses an AAC encoding to wear off unauthorized users from copying the data. The main purpose is the streaming rather than sending video or audio information. MP4 files can be used to store audio streams and, in addition, text information, subtitles and still images while MPEG format can’t do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information.
