HEVC (H.265) Codec

T

Until recently, if you recorded a video with your mobile phone or watched a video on the web, it was most likely encoded with the Advanced Video Coding (AVC) standard. This standard, also known as H.264, was developed in 2003 and it started to become widespread in 2008 after leading platforms like Adobe Flash and Blu-ray Disc adopted it for High Definition Video.

High-Efficiency Video Coding (HEVC, or H.265) is the latest video compression standard developed by the Motion Picture Experts Group (MPEG), finalized in 2013. HEVC is able to compress video up to twice as efficiently as AVC, letting you encode a video in a file that is about half the size of AVC at the same quality level. The higher compression efficiency also means that for a given bit rate or file size, HEVC encodes video with significantly higher quality than AVC.

 

Efficient solution for 4K distribution

The higher compression efficiency of HEVC will enable efficient recording and distribution of Ultra High Definition (UHD, 4K, 2160P) video. While UHD has four times as many pixels per frame (3840 x 2160) as HD video (1920 x 1080), HEVC will enable UHD to be encoded with reasonable bit rates (roughly twice the bits per second required for good HD video today, instead of 4x the bit rate).  While HEVC is essential for efficient storage and distribution of Ultra High Definition video, it provides the same benefit at smaller video picture sizes (High Definition, Standard Definition, etc.). As a result, HEVC is rapidly being adopted by many companies and organizations worldwide. Here is a small sample of the hundreds of products and video services adopting HEVC;
