Grading, Mastering, and Delivering HDR — Mystery Box. If you’ve made it this far through the HDR creation process, there should really only be one major question remaining: how do we encode HDR video in a way that consumers can see it? First, the bad news. There’s no standardization for HDR in digital cinema yet. So if your intention is a theatrical HDR delivery, you’re probably need to work with Dolby. At the moment, they’re the only ones with the actual installations that can display HDR, and they have specialists who will handle that step for you. For most people, what we want to know is how to get an HDR capable television to display the video file properly. This is where things get more tricky. I don’t say that because it’s a necessarily complicated process, but only because there’s no ‘drop in’ solutions that are generally available to do it (other than You. ![]() ![]() Tube, very soon). There are only three codecs that can, by specification, actually be used for distributing HDR video, HEVC, VP9 and AV1 (AV1 is the successor to VP9), and within these only specific operational modes support HDR. And of these three, the only real option at the moment is HEVC, simply because HDR televisions support hardware based 1. HEVC decoding - it’s the same hardware decoder needed for the video stream of UHD broadcasts. ![]() HEVC encoding support is still rather limited, and finding an application with an encoder that supports all of the optional features needed to encode HDR is still difficult. Adobe Media Encoder, for instance, supports 1. HEVC rendering, but doesn’t allow for the embedding of VUI metadata, which means that the file won’t trigger the right mode in the end- viewer’s televisions. Unfortunately, there’s only one encoder freely available that gives you access to all of the options you need for HDR video encoder: x. FFmpeg. If you’re not comfortable using FFmpeg through a command line, I seriously recommend downloading Hybrid (http: //www. FFmpeg frontend I’ve found. Here are the settings that I typically use for encoding HEVC using FFmpeg for a file graded in SMPTE ST. HDR using BT. 2. 02. BVM- X3. 00, at a UHD resolution with a frame rate of 5.

I’ve only listed the settings that I are different from the default x. I use these values. First, x. 26. 5 needs to output a 1. UHD broadcast, SMPTE ST. ARIB STD- B6. 7 or HDR1. To trigger that mode, that I set the Profile to Main 1. Bit Depth to 1. 0- bit. Unless you’re setting a really high bit rate, or using 8. K video, you shouldn’t need a higher Tier than Main. Next, I target 1. If you can tolerate a little flexibility in the final bitrate, I prefer using this mode, simply because it balances render time with quality, without padding the final result. If you need broadcast compliant UHD, you’ll need to drop the target bitrate from 1.
