Just to add a little context to the questions about Lumagen. I have owned many Lumagen products over the past 10 years, and their level of service is second to none. I got my first Radiance Pro in early 2016. I used it for a while and then removed it as I was having hdmi issues. These issues weren’t the fault of the Lumagen, but more the lack of any cables like we have now, that can handle 4K sources over a long distance. This was way before you could even buy the Celerity 18GHz Fiber.
I sold my last Radiance Pro around the beginning of 2017 which only had the 9ghz cards. I just recently bought a brand new Pro with all 18GHz cards.
The software has developed by leaps and bounds over the past two years. I’m getting solid HDMI switching of all 4K sources over a 100’ Fiber cable. All the equipment for my house is located in one central equipment room. From there all video is distributed over a mixture of Rui-Pro or Monoprice 18GHz Fiber cables that run to each of the 8 TVs or 2 projectors installed. The lengths of these Fiber cables I’m using range from 50’ to 150’
But the best feature of the Lumagen is the new “HDR Intensity Mapping” software, which continues to evolve and only get better. I have tried custom curves on both my JVC and Sony projectors. I have tried the features built into UHD Blu-ray players. I own both the Panasonic and oppo. Nothing compares to the Lumagen. I never found a custom curve which was truly “one size fits all” and this is where the Lumagen excels over everything else.
Currently Lumagen has two separate groups of adjustments. One group for under 2500 nit and one group for over 2500 nit. This crossover point is adjustable as well. And these settings are independent for each source as well. This way the Pro can tailor the curve to best fit content regardless if it is was mastered on a 1000 nit or 4000 nit display. Then they adjust each of these groups, not just based on the “Max nit level” but now also look at the MaxCLL and adjust each of the above setting to better match this metadata. This is a much better way making calculations as Max Nit level is really meaningless. It doesn’t matter if content was mastered on a 4000 nit display when the MaxCLL is 500.
But after talking with Jim Peterson this week, this is only going to get better. Unfortunately even the MaxCLL metadata for content can often be wrong. This is something
has been point out in his thread “HDR UHD Waveform”.
So Lumagen is now working on a dynamic process which will actually look at the content in real time and make dynamic calculations for MaxCLL to correct for this sometimes wrong or totally missing data.
They will also be adding HLG and HDR10+ compatibility. Currently I have to route my DirecTV 4K receiver around the Lumagen, because of HLG broadcast, but soon we will be able to use “HDR Intensity Mapping” on that content as well.
For anyone wondering how much of an improvement the Radiance Pro is over a custom curve, just ask Manni. He has worked for the past year or longer on custom curves and even worked with HDFury to create special software and macros which could control JVC projectors and trigger different modes for different content. He has done more work with custom curves than probably anyone else, and once he saw comparisons that Kris Deering showed him between what the Custom curves could offer vs the Lumagen, he pretty much instantly threw in the towel and said he was done messing with custom curves.
The Lumagen offers a fully automated approach where all of this processing and analyzing is happening behind the scenes. Once it’s setup properly, you shouldn’t have to worry if you are missing shadow detail or clipping highlights, and have the peace of mind that you are getting the very best HDR image available.
And as good as the current implementation is we are still at the mercy of existing metadata. But once the Lumagen software is dynamically calculating correct metadata for every title, there won’t be anything that compares.
