What is a MP4 File?
MP4 (MPEG-4 Part 14) is a digital multimedia container format used to store audio and video data. It is a widely used file format for storing and playing back multimedia content, such as movies, TV shows, music videos, and online courses. MP4 files are commonly used on the internet, mobile devices, and digital media players.
History of MP4
The MP4 file format was first introduced in 1998 by the Moving Picture Experts Group (MPEG), a working group of the International Organization for Standardization (ISO). The format was designed to be a successor to the earlier MPEG-4 file format, which was limited in its ability to store audio and video data.
How MP4 Files Work
MP4 files use a container format to store audio and video data, along with metadata such as title, author, and copyright information. The container format is based on the ISO Base Media File Format (ISO BMFF), which provides a standardized way of storing multimedia data.
MP4 files can store a variety of audio and video codecs, including H.264, H.265, AAC, and MP3. The file format also supports multiple audio and video streams, allowing for multiple languages or audio tracks to be included in a single file.
How to Open a MP4 File
MP4 files can be opened and played back using a variety of media players and software applications. Some common ways to open a MP4 file include:
- Media Players: Most media players, such as VLC Media Player, Windows Media Player, and QuickTime Player, can open and play back MP4 files.
- Web Browsers: Many web browsers, such as Google Chrome, Mozilla Firefox, and Microsoft Edge, can play back MP4 files directly in the browser.
