The higher compression efficiency of HEVC will enable efficient recording and distribution of Ultra High Definition (UHD, 4K, 2160P) video. The higher compression efficiency also means that for a given bit rate or file size, HEVC encodes video with significantly higher quality than AVC. 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. 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. This is key if we want 4K/Ultra HD broadcasts (including satellite), 4K Blu-rays, and more. The idea of HEVC is to offer the same level of picture quality as AVC, but with better compression, so there are fewer data to deal with.
It supports resolutions up to 8192×4320, including 8K UHD. In comparison to AVC, HEVC offers about double data compression ratio at the same level of video quality or substantially improved video quality at the same bit rate.
HEVC, short for High-Efficiency Video Coding, also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10).
