H.264 is a widespread video compression codec standard used in various devices, such as internet videos, Blu-ray, phones, and more. Developed over 30 years, it aims to reduce bandwidth for full-motion video transmission. Through lossy compression, H.264 discards less important bits while keeping essential ones to save space efficiently. Additional techniques like chroma subsampling and motion compensation further enhance compression capabilities. The standard involves various intricate processes, including entropy encoding to handle redundancies. Ultimately, H.264 achieves significant compression ratios, such as turning a 1.2 GB video into a 175 KB file, showcasing its impressive efficiency and technical prowess.
