MPEG4 is a high quality video compression algorithm and is suited for all types
of applications with different ranges of bit rates. In addition to MP4 files, MPEG4
compressed video data can be stored inside AVI, OGG and MPEG2 Transport Stream files
with the option of saving the file with or without the audio data.
Most mobile devices (iPod, iPhone, iPad, Windows Phone 7, Android, etc) also support
MPEG4 compressed files.
