It is likely that H.264 (adopted as a standard in 2003) will be widely in service through its 20th year, in 2023. H.264 is used broadly and its operating characteristics and storage requirements are well known by video editors, so its use is continuing. H.264 has given us a window into the lifespan of a compression standard and it is 20 years. It is the availability of hardware which supports new encoding methods that gives long life to standards such as the H.264. With this in mind, widespread adoption of new video compression techniques (like H.265/HEVC) require parallel advances in computing power of end user devices. Advances in related technologies have a direct impact on adoption of each new standard. In each advancement of compression technology, there is a corresponding cost in computing demand on devices whether in the cloud, at the browser and in hardware. There is a new and substantially better compression method (adopted in July of 2020) called H.266 / Versatile Video Coding (VVC) that, yet again, promises better efficiency by up to 50% over H.265/HEVC. As of July, 2020, most popular browsers support HEVC and this will likely continue. H.265/HEVC is widely used and can be found in applications broadly. H.265 in Webcasting and Videoconferencing H.265 is a structural and permanent enhancement to live video conferencing, streaming and archiving. These technology advances will structurally and permanently allow higher quality, near real time video encoding, transport and end-user delivery. Higher speed communications networking with 5G and beyond Massive advances in computing power of user devices, workstations, tablets and phones H.265/HEVC’s improved efficiency over H.264 and prior codecs Taken together there is a convergence of technologies that are advancing the quality of video in modern modern media. Additionally, higher speed data communications 5G cellular networking will multiply the effect of High Efficiency Video Encoding as it will reduce the latency of transmission for live video. These advances in computing power allow the cost of H.265’s computational demands, which can be quite high, to be minimized if not negated over time. The impact of H.265 is multiplied by other factors as well such as significantly increasing computing power of computer workstations, tablets and smart phones. The importance of H.265, in itself, is that it is a highly efficient method of compressing video. The tradeoff for this is that H.265 requires more computing power to process Why is H.265 Important? H.265 is called HEVC for High Efficiency Video Coding, as it can more efficiently produce far greater video clarity of moving images at the same bitrates or storage volume of H.264. The additional efficiency in encoding provided by the H.265 is between 25% and 50% over H.264 in some tests the efficiency improvement is far greater. It offers substantially improved encoding efficiency over H.264, which itself offered breakthrough efficiency. H.265 is a highly efficient encoding method.
