MPG - MPEG Video Stream

What is a MPG file

MPG allows lossy compression with little loss of quality of audio and video for easy downloading due to the less space needed for storage. This file type offers small file sizes with high quality. MPG files are also listed as MPEG-1 and MPEG-2 files. Both types of MPG files serve as container files for audio and video data to ensure the two portions remain in sync. Windows, Mac, and many mobile devices can run MPEG-1 and MPEG-2 files. MPEG-2 is not the most efficient at file compression, but it is commonly used due to compatibility with various programs. Standards for both files under the MPG category were designed by the Moving Picture Experts Group.

MPG in respect to MPEG-1 compresses files to 1.5 mbit/s. Digital video files (ex: VHS conversion to digital) are compressed to a 26:1 ratio, and audio files (CD quality) are compressed to 6:1. MPEG-1 is among the most versatile file types for audio and video, being utilized by various styles of digital audio broadcasting (DAB) for radio, and cable/satellite broadcasts for television. The MPG standards introduced the commonly recognized MP3 audio format. MPEG-2 is utilized for compressing the associated audio and visuals (such as movies). It allows up to 5.1 multichannel audio. The MPEG-2 bit-rate limit is 1 Mbit/s, but video decoders can play lower bit-rate files due to backwards compatibility with MPEG-1 files. MPEG-2 files are often used for cable, satellite, and digital television, as well as DVD and television stations.
