The MP4 file type is a multimedia format designed to store digital video and/or audio streams in addition to 2D and 3D imagery. A common task for end-users who have video or audio content stored in AVI (Audio Video Interleave) format is to convert AVI to MP4 for playback on mobile devices such as the iPod, iPad, or iPhone that require conversion to MP4.
