JDW: Using Rec.2020 HLG on a Rec.709 timeline in FCPX

“This video demystifies use of Rec.2020 HDR footage on a Rec.709 timeline in Final Cut Pro X 10.4.x, especially for Panasonic GH5 & GH5S users who shoot in HLG. I don’t own a SONY camera, but the same workflow shown in my video would apply to Sony Rec.2020 HLG as well. Leeming LUT offers a Sony HLG to Rec.709 LUT….”

The Daejeon Chronicles: How to Work with the Leeming LUT in FCP X 10.4

https://jonpais.wordpress.com/2017/12/26/how-to-work-with-the-leeming-lut-in-fcp-x-10-4/

“Apple has gone ahead and and released what can only be described as a humungous update for Final Cut Pro, including the ability to edit 360° video, advanced color grading tools like curves and wheels, look up tables without the need to use third-party plug-ins, support for high dynamic range video and a whole bunch more….

… But while on the surface, the UI looks reassuringly familiar, those who shoot HLG for rec. 709 delivery using the Leeming LUT may be in for some unpleasant surprises….”

Nick Driftwood: Panasonic Lumix GH5 Hybrid Log Gamma – Video and HLG HDR Workflow Notes

“New HDR Functionality recording with HLG. See the HDR video on Panasonic site at: https://youtu.be/ju35M4gnDBE

… HLG has similar gamma characteristics to SDR in dark range (processing in blacks similar to BT.709 below 100 nits), then changes to a log gamma above ~14 nits. Extends log processing of displays high brightness peaks up to 2.5 to 3 stops to mitigate blown-out or clipped whites. Can be displayed unprocessed on an SDR screen as EOTF adjusts system gamma to correct for viewing environment (10 to 500 nits) Does not require scene mastered metadata unlike PQ (HDR10) or Dolby Vision. Is best for Live production and fast turnaround HDR as you don’t need to grade too much if you’ve exposed to use the extra display stops correctly….

WORKFLOW: I output on a Mac to Pro Rez 422 10-bit (you can use any 10-bit or lossless package on your computer)Iand then recoded to bring the size down and add flags using HEVC. I used FFMPEG which is freely available to Windows, Mac and Linux users to code my HEVC files and to add the necessary HLG and Rec2020 flags which will trigger HDR TVs to play automatically the content in HLG. Here’s an example command line (make sure you download the 10-bit version of x265lib. Mac users should download Homebrew to install a compile.;-
