You will need to configure your output device to send either HLG or PQ output, usually in the Playback Preferences menu, and configure your display to match if needed. High-bit-depth color makes a big difference for HDR content. By default, Premiere plays back at 8-bit and then reprocesses frames at 32-bit when you pause playback. But this behavior can be overridden to be 32-bit all the time by enabling “High Quality Playback” in the Program Monitor Wrench menu. This requires more computing power, but you will definitely see banding at 8-bit with HDR content. Currently, Premiere can’t decode R3D files directly into HDR, but RedCineX can transcode R3D files to ProRes in either HLG or PQ, and you can drop those right into Premiere HLG sequences. Ideally, we will eventually be able to seamlessly edit R3Ds and other raw files directly in Premiere sequences in HDR. The first step in editing HDR content is getting your footage into a supported HDR format. Some cameras can shoot directly to HDR, like Panasonic’s GH5 recording to HLG HEVC files or Sony cameras recording to X-AVC in HLG. Other cameras shoot raw files that can be decoded or converted into HDR color spaces. Someday, once operating systems and applications have their UIs optimized for HDR displays, this will be much simpler, but until that pipeline is standardized and streamlined, monitoring will be the hardest part of editing in HDR or even just viewing HDR content on a computer. I don’t know if running it in OS X has the same results, but neither is officially supported by Adobe at the moment because updates to the OS or the graphics drivers could have significant effects on the accuracy of that output. Enabling Display Color Management in Premiere’s general preferences just caused all of the values above 100 to clip instead of mapping the peak brightness to 100%. I tested connecting my HDR display to my Quadro GPU with an HDMI 2.0 adapter and found that Premiere’s output, in both the Program Monitor Panel and in full-screen Transmit output, was limited to whatever I set the SDR application brightness to in Windows. The only reliable way to view your HDR content in Premiere is with a dedicated hardware output that supports Adobe’s Mercury Transmit. This becomes the reliable link between the software application and the HDMI 2.0 (or SDI) output, which can then be monitored in the standard ways. Currently supported hardware output options include AJA’s Kona cards and Thunderbolt peripherals and Blackmagic’s DeckLink cards. These are then connected to your HDR display, which could be anything from a consumer HDR TV to a mastering-quality Canon DP-V3120, which is what I tested with (powered by a Kona 5 card - check out my piece here.) The last three steps have a solution that has been standardized as HDMI-2.0b, but the step going through the operating system and graphics driver introduce many variables that could be changed by Microsoft, Apple, Nvidia, AMD or Intel. You do want to see what your HDR content looks like, right? The challenge is that the image has to go from the software through Windows to the graphics driver over a digital cable to an HDR display and then be correctly interpreted on that end to be viewed correctly. 2100 in the Working Color Space drop-down menu. Similarly, the export options now have HDR variables for certain formats. H.264 and HEVC files can be exported for delivery in HDR10 with the correct metadata attached, and HDR content can also be exported as ProRes, X-AVC Intra orĬurrently, the big caveat is in monitoring. The Sequence Settings dialog box now offers the options of Rec. 2100 PQ, and there is an option to assign input LUTs to source footage as well. 709 color space. Premiere correctly understands various color space formats and can process them correctly. The Interpret Footage dialog box now has a color management section, where users can choose between Rec. The most important piece of that puzzle is that image processing is no longer only being computed in the Rec. Adobe Premiere Pro now supports editing HDR content. Technically, HDR has been supported in Premiere Pro since 2015, but only if you were using OpenEXR frame sequences and with other severe limitations. This release finally includes a fully developed workflow for editing and finishing projects in HDR.
