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 a WMV file?

Windows Media Video (WMV) refers to a series of video codecs and their corresponding coding formats developed by Microsoft, typically encapsulated in the Advanced Systems Format (ASF) container. The format evolved through several iterations (WMV7, WMV8), culminating in WMV9, which was standardized by SMPTE as VC-1 (SMPTE 421M). WMV utilizes inter-frame compression and was originally designed for internet streaming applications and the Windows Media framework, supporting variable bit rate (VBR) and digital rights management (DRM).

How to open a WMV file

WMV files open natively in Microsoft Windows environments via Windows Media Player and the Movies & TV app. On macOS, native support is absent, requiring third-party tools such as VLC media player or the legacy Flip4Mac component for QuickTime. Cross-platform suites like MPlayer and DivX Player also support the ASF container and VC-1 codec family required to render WMV content.
