MPE

Video Format Description

MPE is the filename extension that identifies an MPEG (Motion Picture Experts Group) video file. In other words, a file with an ‘.mpe’ extension is a video file encoded in the MPEG format, a common compression scheme used to compress digital video files.

The MPEG compression technique is a very sophisticated one. It uses a DCT-based (Discrete Cosine Transform) compression, which reduces special redundancy. Therefore, the MPEG compression removes special redundancy both within the video frame and between video frames. This makes an MPEG file very small without changing the images in a video stream.

There are several MPEG formats available today. The file extension MPE is mainly associated with the versions MPEG-1 and MPEG-2. The MPEG-1 is the initial MPEG compression scheme, which compresses in the ratio range of 50:1 to 100:1. Its video quality is at par with a VHS tape. MPEG-2, the later MPEG version has a better coding quality, thus giving higher quality video playback at higher data rates. The compression ratio can be up to 200:1. Today MPEG-2 is the most commonly used type of MPEG compression most often used to create movies to be distributed over the internet.

The programs that open an MPE file are Microsoft Windows Media Player and Apple QuickTime Player besides most other video players on Microsoft Windows, and the Microsoft Windows Media Player and Apple QuickTime Player on the Mac OS platform.
