Open MPEG-4 Files

MPEG-4 (better known as MP4 ) is a container format suitable for distributing videos over the Internet or to store audio and video streams.

MPEG-4 is based on separate compression methods for its audio and video components, more precisely videos use MPEG-4 encoding and audio features AAC compression.

This format was initially used on the Microsoft Zune portable media player, but it is currently supported by other devices and applications as well.

Furthermore, MP4 players will enable users to easily add their favorite tracks within playlists.
