H264, also known as Advanced Video Coding (AVC), is a widely used video compression standard that revolutionized the digital video industry. Developed by the Joint Video Team (JVT) consisting of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG), H264 offers superior video quality while reducing file sizes.

With its efficient compression algorithm, H264 enables high-definition video streaming, video conferencing, and video storage on various devices. It utilizes advanced techniques like motion compensation, entropy coding, and transform coding to achieve optimal compression ratios without compromising visual fidelity.

Supported by most modern browsers and devices, H264 has become the de facto standard for video encoding. Its widespread adoption ensures seamless video playback and compatibility across platforms, making it an indispensable tool for multimedia content creators and consumers alike.
