HEVC/H.265 video format

- OTHER

The High Efficiency Video Coding (HEVC) compression standard is a video compression format intended to succeed H.264. It is hard for browsers to universally support HEVC because it is complex and expensive to license. HEVC competes with AV1 which has similar compression quality and provides a free license.
