What is it?
MPG (along with the equivalent .mpeg extension) denotes digital video files compressed using the MPEG-1 or MPEG-2 standards developed by the Moving Picture Experts Group under ISO/IEC. MPEG-1 was published as ISO/IEC 11172 in 1993, and MPEG-2 followed as ISO/IEC 13818.
An MPG file typically carries an MPEG program stream that multiplexes compressed video and audio together. MPEG-1 was designed to deliver VHS-quality video at around 1.5 Mbit/s for Video CDs, while MPEG-2 added interlaced video and higher quality for DVDs and digital television broadcasting.
Technical Specifications
Pros & Cons

Defined by open ISO/IEC standards, ensuring predictable, interoperable decoding.
MPEG-1 and MPEG-2 made digital video practical on CDs, DVDs, and broadcast channels.
The program/transport stream design supports continuous playback and broadcast delivery.
Disadvantages
MPEG-1/2 produce far larger files than modern codecs like H.264 or H.265 for the same quality.
Designed for standard-definition content rather than today's HD and 4K video.
MPEG-2 was subject to patent licensing for much of its life, though core patents have now expired.
When to Use It
MPG remains tied to legacy optical media and broadcast workflows.

How to open a MPG file
MPG files, which are based on the MPEG-1 and MPEG-2 video formats, can be handled by a variety of software tools tailored for different user needs. Professional video editing software is ideal for filmmakers and content creators who require advanced editing features, while free and open-source options cater to casual users or those with budget constraints. Browser-based tools provide convenience for quick tasks without installation, and built-in media players offer basic playback functionality for everyday users.
When choosing software for MPG files, key factors include the fidelity of video playback and editing capabilities, as well as the cost model that fits the user's budget. Users should consider whether they need robust editing features or simple viewing options, the platform compatibility, and any specific export requirements. In some cases, converting MPG files to more widely supported formats may be a better option depending on the intended use.
