The format was designed to provide a standardized way of storing and playing back multimedia content. Over the years, MP4 has undergone several revisions, with the latest version being MP4v2, which was released in 2003.
Key Features of MP4
So, what makes MP4 such a popular format? Here are some of its key features:

How Does MP4 Work?
So, how does MP4 work its magic? Here’s a simplified overview of the process:
- Encoding: When you create an MP4 file, the multimedia content is encoded using a codec (encoder-decoder). The codec compresses the data, reducing its file size.
- Containerization: The encoded data is then stored in an MP4 container, which is a file that contains the multimedia content and metadata such as subtitles and images.
- Playback: When you play back an MP4 file, the container is read by a media player, which extracts the encoded data and decodes it using a codec.
MP4 File Structure
An MP4 file consists of several components, including:
- Header: The header contains metadata such as the file size, creation date, and author information.
- Tracks: The tracks contain the multimedia content, such as video and audio.
- Chunks: The chunks are small blocks of data that make up the tracks.
- Atoms: The atoms are the smallest units of data in an MP4 file, containing information such as the track type and codec.
Applications Of MP4
MP4 is a versatile format that has a wide range of applications, including:
- Video sharing: MP4 is widely used for sharing videos on social media platforms, YouTube, and other online video sharing sites.
- Streaming: MP4 is used for streaming multimedia content, including live events and on-demand videos.
- Gaming: MP4 is used in the gaming industry for storing and playing back game videos and trailers.
