What Are MP4s and How Do They Work?
MP4, or MPEG-4 Part 14, is a digital multimedia container format that is widely used for storing video, audio, subtitles, and still images. It was developed by the Moving Picture Experts Group (MPEG) and first introduced in 2001. The format quickly gained traction due to its ability to deliver high-quality multimedia content in a compact file size. MP4s are designed to be highly versatile, supporting a wide range of codecs such as H.264 for video and AAC for audio. This flexibility allows MP4s to be compatible with virtually any device or platform, from smartphones and tablets to desktop computers and smart TVs.
At its core, MP4 is a container format, meaning it acts as a wrapper for various types of data. This includes video streams, audio streams, metadata, and even subtitles. The container itself does not define how the data is encoded; instead, it relies on codecs to compress and decompress the content. For example, a video file in MP4 format might use the H.264 codec for video compression and the AAC codec for audio compression. This separation of container and codec allows MP4s to be highly adaptable, supporting different types of media and encoding standards. As a result, MP4s can store everything from high-definition videos to low-resolution clips without compromising quality.
