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. So why has Apple adopted the HEVC format, and what difference will it make to the end user?
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. 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.
