Play MPEG4 Files

MPEG4 (better known as MP4) is a video file format used for storing digital video and audio streams and for easily sharing video files over the web.

The MPEG4 multimedia format uses separate compression for its video and audio tracks, so that the video track is compressed using a MPEG-4 video encoding, while the audio may be based on AAC compression.

MPEG4 video files may be be played using both apps and portable devices, such as the Microsoft Zune portable media player.

Users will also be able to use their MP4 playing applications to quickly adjust the bit rate or the aspect ratio for their video source files.
