![]() ![]() To put that another way, a HEVC video file offers significantly better visual quality than an AVC file of equivalent size or bit rate. ![]() The HEVC standard enables a video to be compressed into a file that is about half the size (or half the bit rate) of H.264 / AVC. (You can learn more about HEIF here.)Īpple's decision to adopt HEVC basically means two things - higher quality video and better compression rates. The HEVC video format has been in existence since around 2013, and HEIF is the still-image version of the standard that both iOS 11 and macOS High Sierra also support. High Efficiency Video Coding (HEVC), also known as H.265, is a next-generation video compression standard developed by a group of encoding experts called the Joint Collaborative Team on Video Coding. So why has Apple adopted the HEVC format, and what difference will it make to the end user? With the arrival of iOS 11 and macOS High Sierra, Apple is supporting a new video format called HEVC, which replaces the previous standard most commonly used on Mac and iOS devices, namely H.264 / AVC.
