![]() ![]() The “natural” content consisted of real-world images captured by a camera, and the “synthetic” content was from Sintel, a test movie created with the 3D graphics application Blender. ” The study tested two different kinds of images: “natural” content and “synthetic” content. The more powerful CPUs that live in our new smart TVs, tablets, and phones can decode more data out of the networks without requiring more bandwidth, all else being equal.Ĭlaims about being able to more efficiently compress data into cutting-edge video codecs are exciting-but should you believe all the hype about equivalent quality?Īn initial working group study that took place from 2013 to 2016 found that HEVC “clearly exhibited a substantial improvement in compression performance, as compared to AVC. The infrastructure won’t immediately require more bandwidth. 709 video will be able to deliver more data into our video: higher dynamic range, wider color gamuts, and larger resolutions. What this means is that the networks that we already use to deliver our HD SDR Rec. HEVC, on the other hand, requires even less storage space than H.264, yet it requires even more CPU power. In years past, digital intermediates like ProRes or DNxHR would eventually be converted to H.264 for web or broadcast. HEVC is just the latest continuation of the trend in trading storage for computation. With CPUs in the last decade or so becoming ever more powerful, cheaper, and more abundant, there has been an industry-wide trend to trade storage space on hard drives for computation via CPUs. The choice to use any particular codec is always partly informed by what particular hardware is available. HEVC was specifically created to provide UHD HDR deliverables with wider color gamuts, rather than just the HD SDR Rec.709 deliverables of H.264. If you’ve read our definitive guide to codecs, you should already be familiar with H.264. In short, HEVC is the successor to the H.264 codec. So it’s time to sit down and take a good look at this new video technology and discover how it can benefit your video workflows. Challengers like VP9 and AV1 have powerful allies in the fight for our screens. But there is growing competition in the realm of futuristic codecs. If HEVC takes off, it will shape the industry for years to come. This sort of performance is what we dream about as video professionals, and could simplify and improve the jump to ultra high definition production. Which could pave the way to an even more ambitious 8k HDR future. HEVC promises to deliver high-quality 4k video that’s up to 75% smaller than before. This fanfare should come as no surprise to anyone in the video industry. Other hardware and software vendors keep announcing new support almost every month. ![]() Apple integrated this next-generation codec into MacOS High Si erra, and professional NLEs FCP X and Premiere Pro now support it. You may have heard a lot about high-efficiency video coding or HEVC recently. ![]()
