What is a .MPEG2 file?
The .MPEG2 file extension refers to a video file that uses the MPEG-2 codec for encoding. This type of file is commonly used for compressing video content that is broadcast via over-the-air signals, satellite, and cable TV, as well as for storing video on DVDs. The MPEG-2 codec employs a method known as lossy compression, which significantly reduces the file size by simplifying some data. This means that while the file becomes smaller and easier to store or transmit, some quality from the original video and audio might be lost.
MPEG-2 is an older compression technique, especially when compared to more modern methods like H.264 (also known as .H264), which is more efficient in terms of the quality and size of the video files it produces.
Various programs can open .MPEG2 files, including: 1. **VideoLAN VLC media player** - This is a versatile, free media player that can handle a wide range of video formats, including MPEG-2. It is available for multiple operating systems. 2. **Microsoft Windows Media Player** - Typically included with Microsoft Windows operating systems, this player can open MPEG-2 files. 3. **Apple QuickTime Player** - This player is included with macOS and can also open MPEG-2 files. 4. **Aiseesoft Video Converter Ultimate** - This is a paid software option that, in addition to playing MPEG-2 files, allows for the conversion of files into different formats. 5. **Aiseesoft Mac Video Converter Ultimate** - Similar to its counterpart for Windows, this software for Mac also supports playing and converting MPEG-2 files.
The MPEG-2 standard was developed by the Moving Picture Experts Group (MPEG), an international team dedicated to setting standards for video and audio compression and transmission. First established in 1995, MPEG-2 improved upon the earlier MPEG-1 standard and has been widely adopted in various media and broadcast systems. Although .MPEG2 files are not as commonly used as .MPG or .MPG2 files, which also contain MPEG-2 video, they are still supported by many media players and software. Audio files using MPEG-2 compression are saved with the .MP2 extension.
