H.264 vs H.265 - What's the difference?
Also known as High Efficiency Video Coding (HVEC) and MPEG-H Part 2, H.265 is a video compression standard designed for the newest generations of high-resolution video. It’s a successor to the widely-used H.264 codec (also called AVC or MPEG-4 Part 10) and offers some major improvements over that now-aging compression scheme. H.265 was developed by the Joint Collaborative Team on Video Coding (JCT-VC), a group of video coding experts that started working on the compression standard back in 2010.
