Description

MP4 is one of the most popular formats for multimedia storage and distribution. It is a container for processing of wide data range, from text and graphics to sound tracks and video. Also it is able to support high-quality files, such as 3D-graphics or user’s menus. It is provided in two versions: MPV (for audio) and M4A (for video). A less known extension .mpr is being used for ringtones.

MP4 files may be played by a number of programs, including Adobe Flash, Roxio Creator, Nero Multimedia Sulte, and a default plug-in Windows Media Player. They are adapted for Mac OS and supplied by modern portable players.

Technical details

MP4/MPEG-4 has been widely used since 2001. By its nature, it is similar with MP3 although more technically complex. It involves AAC coding method and complies with the standards of ISO/IEX 14496-1. Video and audio contained in a MP4 file is usually played in real time. Thanks to extra information (e.g. file name or images) it differs significantly from MPEG. Often it is impossible to embed data in such a file without use of separate streams that commentary tracks are integrated to.

Description

Apple Inc. has designed M4A format on the basis of QuickTime Fike. Now the format is being promoted in iTunes. It is a multimedia container intended for placement of sound components, as well as other data, such as images. MPEG-4 files may be stored with extensions M4A and MP4. In the latter case, they contain video as well.

Alongside these sound formats, MPEG-4 allows for lossy compaction, through FFC Codec. However, it is possible to provide a lossless compaction thanks to Apple Lossless format. The files may be played on Windows PCs via iTunes, Windows Media Player 12, KSP Sound Player, Winamp and some other programs. With iTunes, the data can be converted into Windows-supported audio formats.

Technical details

In comparison with its predecessor MP3, M4A format provides with better sound quality and smaller file size. Thanks to lossless compaction, the data may be easily converted in both direction with no deterioration in quality. The sound data encoded with ACC compression, which reduces the file size considerably.

Due to protection technology DRM, MP4 files cannot be easily distributed, while it is much simpler to replicate files in M4A; that is why “Apple Lovers” prefer the latter format. With M4A, it is possible to buy music in iTunes, as well as download it into smartphones or other devices.
