What is a MPG file?
Common MPEG video format for DVDs and broadcasts
MPG files are common video files that uses a compression algorithm that was standardized by the Moving Picture Experts Group (MPEG). Video, audio, subtitles, and other metadata is interleaved together as a convenient container for distributing movies across the Internet. MPG files usually incorporate either MPEG-1 or MPEG-2 for audio and video compression. MPEG-1 is one of the most popular lossy video and audio formats and it widely accepted by media players and devices. MPEG-2 is the newer version of MPEG-1 which can have more than two audio channels and supports higher resolution videos such as 4k and 8k.

Who works with MPG files?
Media archivists, librarians, and post-production teams work with MPG files when digitizing or restoring footage from older tape and disc workflows, since MPEG-1 and MPEG-2 were the dominant standards of that era. Legal, government, and corporate teams also encounter them when reviewing older surveillance footage, training videos, or archived recordings that predate modern formats.
MPG vs MP4: which should you use?
MPG files use the older MPEG-1 or MPEG-2 codecs in a program stream container, while MP4 files typically pair H.264 video with AAC audio in the MPEG-4 Part 14 container. MP4 achieves comparable quality at noticeably smaller file sizes and is the default for web, mobile, and streaming platforms. MPG remains relevant mainly for DVD authoring and legacy broadcast or archival workflows where MPEG-2 compatibility is required.
