Compared to H.264, the video stream size encoded by H.265 is approximately 39-44% less than H.264. At the same time, H.265's intra prediction mode supports 33 directions (H.264 only supports 8), and provides better motion compensation processing and vector prediction methods. Why H.265 over H.264?Ĭompared to H.264/AVC, H.265/HEVC provides more different tools to reduce the bit rate, in terms of coding units, from a minimum of 8x8 to a maximum of 64圆4. This standard is often referred to as H.264/AVC (or AVC/H.264 or H.264/MPEG-4 AVC or MPEG-4/H.264 AVC) and clearly states its developers. Highly compressed digital video codec standard. H.264, also part of MPEG-4, is proposed by the Joint Video Team (JVT, Joint Video Team) composed of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Motion Picture Experts Group (MPEG). The biggest benefit of this format is that it can save 50% more space than other formats, which is important for users who frequently take ultra clear video. On January 26, 2013, HEVC officially became an international standard. HEVC (High Efficiency Video Coding) is a new video compression standard used to replace the H.264/AVC coding standard.

The new technology uses advanced techniques to improve the relationship between codestream, coding quality, delay and algorithm complexity to achieve optimal settings.

The H.265 standard revolves around the existing video coding standard H.264, retaining some of the original technologies and improving some related technologies. H.265 is a new video coding standard developed by ITU-T VCEG following H.264.
