Mark is correct, and I too have an AX700. The only RAW HLG clips I was able to play back directly on my LG TVs, were the GH5’s 10 bit HLG clips. Sony’s version of HLG on all their consumer cameras (including the A7iii) is only 8bit and thus not recognized as true HLG.
There are only 2 solutions to the issue that I’ve found, one very simple but now very elusive & expensive and the other very easy with a caveat.
First solution- I have always used an Oppo 203 BluRay player for HLG playback of Sony’s RAW files. I use any of the Oppo’s USB inputs using an SD card reader. The reason this works is that the Oppo converts the 8bit Sony HLG to 10bit and it does this on the fly. The files are still really 8bit, but the on the fly conversion to 10bit is enough to fool HLG-capable displays into reading them as ‘genuine’ 10bit HLG. It works flawlessly.
The problem with this solution is that the Oppo is no longer available at normal retail and can only be found at scalper prices ($1,200 in many cases). I have a new Panasonic 805 BluRay player and despite the rave reviews it has received, it will not play Sony’s 8bit HLG files via the USB inputs. It would appear that only the Oppo can do an 8bit to 10bit on the fly conversion.
Second solution- In the editing process, as long as your editor permits, you can export your project as a 10bit HLG compliant video. As long as your parameters are set correctly, you’ll now be able to play back your project in HLG on your TV.
The issue you’ll have is that you won’t be able to see your clips in HLG as you edit. I never found that to be a deal-breaker since it rarely caused significant issues in judging my final output.
The problem (for me) that I’ve come to realize over time, is that I’m not enthralled with the color quality I see in HLG. This was true even using the 10bit HLG capability of the GH5. I’m not sure why this should be, but for me it’s enough of an issue with Panasonic or Sony, 8bit or 10 bit, that I’ve essentially stopped using it. Others may disagree, but for me it’s an issue.
Edit: Although I can’t recall testing it, it’s my understanding that recent vintage Sony TVs will play back Sony 8bit HLG properly. This is obviously not a practical solution unless you were already seriously considering a Sony TV and verified this capability.
