What is an MPG file?
The MPG file extension is functionally identical to the MPEG format, restricted historically to a three-letter filename in MS-DOS and early Windows environments (8.3 filename convention). It typically contains video and audio interleaved in an MPEG-1 or MPEG-2 Program Stream (PS) container. MPG files are standard for VCD (Video CD) and DVD-Video content, utilizing inter-frame compression to reduce file size while maintaining VHS-comparable or broadcast-quality resolution depending on the bitrate and standard version utilized.
How to open an MPG file
Due to its legacy status as a standard distribution format, MPG files open natively on almost all desktop and mobile platforms without external codecs. Windows Media Player, Apple QuickTime, and GNOME Videos handles MPG-1 and MPEG-2 streams automatically. If playback issues occur due to corrupted headers or proprietary data streams, VLC Media Player is the industry-standard fallback utility.

What is an MKV file?
The Matroska Video (MKV) file is an open-standard, free container format capable of holding an unlimited number of video, audio, picture, or subtitle tracks in one file. Unlike proprietary containers, Matroska is structured upon Extensible Binary Meta Language (EBML), allowing for significant flexibility and forward compatibility. It supports a vast array of codecs, including H.264, VP9, HEVC, AAC, Vorbis, and FLAC, and is particularly noted for its support of soft subtitles (SSA/ASS) and chapter entries, making it a standard for high-definition video distribution (HD) and anime fansubs.
How to open an MKV file
Native support for MKV is available in Windows 10/11 via the Movies & TV app and generally on Linux distributions. macOS requires third-party software, as QuickTime Player does not natively parse the Matroska container. The industry-standard solution for all operating systems is VLC Media Player, which includes built-in libraries for decoding the diverse codecs often encapsulated within MKV files. Alternative options include MPV and MPC-HC (Windows).
