What is MPG? MPG is a file extension for audio and video files using MPEG compression formats. MPEG compression formats are developed by Moving Picture Experts Group (MPEG).

Technical notes on MPEG file formats:

• MPEG-1: Initial video and audio compression standard.
• MPEG-2: Transport, video and audio standards for broadcast-quality television.
• MPEG-3: Originally designed for HDTV, but abandoned when it was realized that MPEG-2 (with extensions) was sufficient for HDTV.
• MPEG-4: Expands MPEG-1 to support video/audio "objects", 3D content, low bitrate encoding and support for Digital Rights Management.
