HEVC H.265 Codec

Until recently, recording video with your mobile phone or watching video on the web means that they are most likely encoded with the Advanced Video Coding (AVC) standard. This standard, also known as H.264, was developed in 2003 and it started to become widespread in 2008 after leading platforms like Adobe Flash and Blu-ray Disc adopted it for High Definition Video.

 

What is HEVC H.265 Codec

High-efficiency Video Coding (HEVC H.265 codec) is the latest video compression standard developed by the Moving Picture Experts Group (MPEG), finalized in 2013. HEVC can compress video up to twice as efficiently as AVC. As a result, the encoded video file is about half the size of AVC at the same quality level. The higher compression efficiency also means that for a given bit rate or file size, HEVC encodes video with significantly higher quality than AVC.

The higher compression efficiency of HEVC will enable efficient recording and distribution of 8K High Definition video. While 8k has 16 times as many pixels per frame (7680 × 4320) as HD video (1920 x 1080), HEVC will enable 8K to be encoded with reasonable bit rates (roughly twice the bits per second required for good HD video today, instead of 4x the bit rate). While HEVC is essential for efficient storage and distribution of 8K High Definition video, it provides the same benefit at smaller video picture sizes (UHD, High Definition, Standard Definition, etc.). That is the reason, while numerous companies and organizations worldwide rapidly adopted HEVC.
