![]() The second version, with multiview extensions (MV-HEVC), range extensions (RExt), and scalability extensions (SHVC), was completed and approved in 2014 and published in early 2015. The first version of the HEVC standard was ratified in January 2013 and published in June 2013. The ISO/IEC group refers to it as MPEG-H Part 2 and the ITU-T as H.265. ![]() HEVC was standardized by the Joint Collaborative Team on Video Coding (JCT-VC), a collaboration between the ISO/ IEC MPEG and ITU-T Study Group 16 VCEG. Effective use of these improvements requires much more signal processing capability for compressing the video, but has less impact on the amount of computation needed for decompression. The primary changes for HEVC include the expansion of the pattern comparison and difference-coding areas from 16×16 pixel to sizes up to 64×64, improved variable-block-size segmentation, improved "intra" prediction within the same picture, improved motion vector prediction and motion region merging, improved motion compensation filtering, and an additional filtering step called sample-adaptive offset filtering. These redundant areas are then replaced with a short description instead of the original pixels. ![]() Both work by comparing different parts of a frame of video to find areas that are redundant, both within a single frame and between consecutive frames. In most ways, HEVC is an extension of the concepts in H.264/MPEG-4 AVC. The High Efficiency Image Format (HEIF) is based on HEVC. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses both integer DCT and discrete sine transform (DST) with varied block sizes between 4×4 and 32×32. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. High Efficiency Video Coding ( HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). SG16 (Secretary: Simao Campos) ( VCEG), MPEG HEVC / H.265 / MPEG-H Part 2 High efficiency video coding Thanks for watching.Video compression format, succeeds H.264/MPEG-4 AVC But as far as getting that free HEVC codec for Windows 10, that’s how it’s done. If you like my video style, you may want to subscribe to be notified of more good stuff as it comes out. If you did, be sure to thumbs me up and comment. Don’t be fooled by more attempts from Microsoft to get you to sign in or create an account you don’t need to do any of that. You don’t need to sign-in with Microsoft unless you want to I don’t want to so I’m clicking “No thanks.” And finally you can click “Install”. Once Microsoft’s done bouncing you around a little bit, you’ll end up at this page that says “HEVC Video Extensions from Device Manufacturer.” That’s the one you want. Otherwise just click ‘Get’ and click “Open Microsoft Store”. ![]() Here you can check the system requirements if you’re curious. You don’t need to sign up for anything if you’re already signed up that’s okay too. Once you click my link, it’ll send you to the Microsoft Store website. What you can do is just hit this redirection link on my website (I’ll provide it in the description for the video and in the companion blog post). Basically, Microsoft wants to sell you the software codec, but if you have a video board that supports HEVC, you don’t need it. If you go to open a video file and get this message, this video is for you. Welcome to the Grok Shop! Super quick video here on how to get that free HEVC codec for Windows 10. Note: most peeps will want the “圆4” one, so try that one if you are not sure which one you need. However, it appears they are still available if you know where to look… Unfortunately, it appears that MS no longer publishes this information on their site or through their “app store” app. If you want to play HEVC or h.265 videos in Windows 10, and you have a video board with a built-in HEVC codec, you can download this free “app” (hevc video extensions from device manufacturer ) from the Microsoft store which will use you video boards built-in HW codec. The URL download link to get the Free Windows 10 HEVC Codec is shown and the installation is demonstrated.
