H.265 (also known as HEVC, short for High Efficiency Video Coding) is a video compression standard whose predecessor is H.264. HEVC was designed to deliver video quality identical or better than to H.264, but with greater compression, so there's less data to deal with. This is key for 4K/Ultra-HD broadcasts, 4K Blu-rays, and more.

In most ways, H.265 HEVC is an extension of the concepts in H.264/MPEG-4 AVC. In comparison to H.264, it offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K Ultra-HD.

H.265/HEVC H.264/AVC
Names MPEG-H, HEVC, Part 2 MPEG 4 Part 10, AVC
Approved date 2013 2003
Progression Successor to H.264/AVC Successor to MPEG-2 Part
Key improvement * 40-50% bit rate reduction compared with H.264 at the same visual quality
* It is likely to implement Ultra HD, 2K, 4K for Broadcast and Online (OTT)
* 40-50% bit rate reduction compared with MPEG-2 Part
* Available to deliver HD sources for Broadcast and Online
Support up to 8K Yes No. Support up to 4K.
Support up to 300 fps Yes No. support up to 59.94 fps only.


In short: H.265 is the video compression standard of the future. Apple has already applied this technology to its iPhone 6 and larger iPhone 6 Plus for FaceTime over cellular. Other companies are urgently gearing up to launch H.265 converters to convert videos from/to H.265.
