In fact, it's estimated that more than 91% of video industry developers rely on H.264, due to its success at providing good quality at lower bit rates! A Quick H.264 Analogy It quickly came to dominate the video landscape with its block-oriented compression standard, including online video, broadcast television, and physical disc formats like Blu-ray. The H.264 video compression format (or codec) originated in 2003, developed by the ITU-T Video Coding Experts Group (VCEG) and the JTC1 Moving Picture Experts Group (MPEG). Video compression allows you to shrink the size of the video file you're transmitting, whether for on-demand video or for live streaming. H.264 is a video compression standard (also referred to as Advanced Video Coding, or AVC) used as the basis for recording, compressing, and transmitting high-definition digital video on the web.īasically, whenever you want to transfer data from one place to another over the web, you need a way to move it there more efficiently. Let's start off with a quick definition of H.264: Read on! What is H.264? And Why Does It Matter? We're here to dive into everything you need to know! Ready for our full answer to the question, "What is H.264?" What really matters is being able to provide a great experience to your viewing audience using the best technology out there for video hosting and playing. That's why we're going to take a different approach in this post: explaining the concept of video compression for non-experts who want to understand H.264 at a high level, including how to use it optimally in your videos as a creator, media company, or enterprise. H.264 ushered in a new widespread adoption of video communications as a result of H.264 Codec implementations.Whenever you're learning about a technical concept like H.264, it's pretty easy to get overwhelmed by all the jargon! This reduction in bandwidth for transmission has enabled higher quality communication throughput at low rates of data transmission bandwidth. H.264 Codecs built into streaming systems and video conferencing systems enabled reduced transmission bandwidth for webcasts and video conferences. The widespread proliferation of high-quality HD webcasts and video conferencing, in large part has been built on the H.264 compression standard and, in turn, H.264 Codecs. H.264 in Webcasting and Videoconferencing These Codecs allow interoperation of systems and communications devices. H.264 compression techniques have given rise to Codecs that are based on this standard and these codecs are embedded in browsers, applications and hardware. Standards allow manufacturers to build software and hardware that can interoperate broadly. The key efficiency H.264 delivers is that it reduces storage and transmission requirements for high quality video by approximately 50%.Īn additional advantage of H.264 as a standard is that it is part of a roadmap of standards that are bringing improved quality and efficiency to video storage and transmission. Its widespread adoption has allowed video to proliferate in transmission and storage archives. The importance of H.264 is that it is a defined standard that manufacturers can build to and implement in both hardware and software products. Often, but not always, H.264 is encoded with the AAC audio codec and in this way, H.264 includes audio. Lower bit rates and file sizes have enabled better throughput of video through communications systems and this has allowed widespread adoptions of video tools, video conferencing and video storage. H.264 achieved widespread adoption and as a result it is included in many video transmission methods and storage applications globally. The standard is scalable to include higher resolutions such as 4K and 8K. This standard provides an improvement in compression efficiency over MPEG-2 as it produces approximately a 50% reduction in file size for comparable video quality. Many organizations have developed compression methods that have contributed to H.264 and the standard which is called “MPEG-4 Part 10 / Advanced Video Coding or MPEG-4 AVC”. It was developed in part to address the large file sizes of prior compression techniques and to allow flexibility in the sources of compression. It is sometimes called MPEG4-AVC, which is consdered Advanced Video Coding. H.264 is a compression standard for high definition (HD) digital video.
