An in-depth technical walkthrough explaining the remarkable efficiency of the H.264 video compression codec. The author demonstrates that a 300-frame H.264 video of the Apple homepage (175KB) is five times smaller than a single PNG frame (1015KB), illustrating the power of decades of compression research. The article covers the basics of why compression is necessary and previews the many techniques H.264 employs.
Background
H.264 (also known as AVC) is one of the most widely used video compression standards since its finalization in 2003, powering everything from streaming platforms to Blu-ray discs and video conferencing. The Apple homepage comparison illustrates a well-known demonstration of temporal compression efficiency.
