Part 2: How to Download HEVC Codec for Windows 10 In terms of coding units, the size of each macroblock (macroblock / MB) in H.264 is fixed at 16x16 Pixels, and the coding unit of H.265 can be selected from the smallest 8x8 to the largest 64圆4. The theoretical value is 30% ~ 40%.Ĭode reduction rate: Compared with H.264 / AVC, H.265 / HEVC provides more different tools to reduce the bit rate. If the storage space is the same, it means that H.265 will have a higher picture quality than H2.64 at the same bit rate. Storage space and picture quality: With the same picture quality and the same bit rate, H.265 takes up 50% less storage space than H2.64. The new technology uses advanced technology to improve the relationship between the code stream, encoding quality, delay and algorithm complexity to achieve the optimal setting. H.265 is a new encoding protocol, that is, an upgraded version of H.264. What are the differences between HEVC and H.264/AVC? Higher Compression rate: with H.264 standard 2- on the basis of 4 times the compression rate, the HEVC compression efficiency is more than doubled. Higher frame rate: HEVC relative to the previous generation standard can save 50% code rate (especially effective for high-resolution video), digital video frame rate from 30fps to 60fps, 120fps or even 240fps application scene upgrade HEVC is increasing the compression rate to H.264 / MPEG-4 A High Definition: The application format of digital video is fully upgraded from 720P to 1080P. For consumers, we can enjoy higher High-quality 4K video, 3D Blu-ray, and high-definition TV program content. HEVC compression scheme can increase the compression efficiency of 1080P video content by about 50%, which means that the quality of video content will increase a lot, and can save a lot of network bandwidth.
It is a new successor to Advanced Video Coding (AVC), also known as H.264, and it is one of the compression schemes used by Blu-ray. The idea of HEVC is to provide the same level of image quality as AVC, but with better compression, so less data needs to be processed. High Effective Video Coding (HEVC), also known as H.265, can achieve twice the compression through Blu-ray's best video compression method. Part 1: Some Information You Should Know about HEVC 1.
