MPEG-4 or commonly known, as the MP4 format, has been around for almost two decades. Its versatility to combine subtitles, metadata, and the supreme H.264 codec made it a popular choice. The only caveat to its use was the fact that it is patented. Using it would require a license from the companies holding its patent. Google took cognizance of the issue and developed an open-source format, WebM. It works flawlessly on HTML 5 supporting browsers without requiring any sort of commercial license.

The standard MP4 format contains the H.264 codec, a relatively video codec, and the newer H.265video, whose wide adaptability is a far-fetched dream. On the other hand, WebM adapted VP9, a relatively superior and next-generation video codec supported across all major browsers.
