Overview

HEVC, short form for High Efficiency Video Coding, is a video compression standard successor to H.264/MPEG-4 AVC. So HEVC also known as H.265. HEVC is targeted at next-generation HDTV displays and content capture systems which feature progressive scanned frame rates and display resolutions from QVGA (320×240) to 4K UHD 4320p (8192×4320), as well as improved picture quality in terms of noise level, color spaces, and dynamic range. HEVC was designed to substantially improve coding efficiency compared to H.264/MPEG-4 AVC HP, that is to say, to reduce bitrate requirements by half with comparable image quality, at the expense of increased computational complexity. Given the same quality video, HEVC H.265 video can reduce file size of 52% for 480p video, 56% for 720p video, 56% for 720p video, 62% for 1080p video and 64% for 4K UHD video compared to H.264/MPEG-4 AVC.
