GH5 V-Log LUT

I know you have done measurements so I do not doubt your findings but my question is how can that possibly be?

HLG only diverts from Rec709 over a certain luminance level, below it is exactly the same as Rec709.
So the question is how are the blacks and shadows encoded in sufficient detail given the fact that they are so far removed from the PQ curve?

How do the blacks under HLG behave? Do they gracefully disappear into the noise or are they compressed and clipped?

This Wolfcrow video https://www.youtube.com/watch?v=JdKwfEv145A I found useful in that I get that the HDR expansion into the shadows for the average viewer is not visible. So the highlights are where the average viewer will see the change. In this regard I expect that HLG has this advantage. That is my understanding at the moment. I like shooting at 60P so for me I will have to get an Atomos Inferno to shoot HLG with my GH5. On my list !!!

The average viewer has no fully HDR capable display available yet.

But should content providers who make content that is going to be enjoyed for years to come make decisions on the current average viewer capabilities?
Wouldn't that be like saying at the dawn of color TV, well we only do B&W because the average viewer doesn't have Color?

And yet a lot of that B&W content is still just as enjoyable. Plus I think the difference going from B&W to color was a heck of a lot more dramatic and had a lot more consumer interest vs SDR to HDR. Consumers only really adopted 4k because stores more or less force buyers into 4k decisions and make it seem utterly ridiculous to even consider buying the HDTVs. I'm sure at some point consumers will be force fed HDR as well just so stores can sell TVs but at the end of the day I highly doubt clients/consumers are going to notice a difference between SDr and HDR or demand it in some way. Some may notice but I don't think its going to be a must for a very long time.

When HD cameras first came out there were still plenty of people shooting and delivering DV/DVD. When 4k cameras came out there are still plenty of people only working and delivering in HD. Most of this content will be just as enjoyable down the road as it is today. Heck watching Golden Girls on Hulu looks horrible but is still just as entertaining.
 
The problem that he points out to me is that in a normal room the light level is such that the advantage of the HDR black levels cannot be seen, even on a HDR screen. So a waste of bandwidth ? Highlights are different and with HLG the user has control of TV set brightness not so with PQ HDR10 where the content provider has the control of TV setup. For some people this may not be that good depending on the room lighting etc. I am moving to thinking that HLG has an advantage in this case as the viewer has control over set brightness something that I want when I watch. Certainly an advantage in transition to better TV's and that may seal its use just like VHS did in the past.

Without a direct comparison? No, they probably won't.

But the standard shouldn't be what average consumers will notice. The standard for all should be what the videophiles and audiophiles will notice. Not doing so is what gave us MP3 instead of 5.1 music as the norm. Not doing so is what caused the superior CRT and Plasma technologies to die an early death. Not doing so is why we have to pay an extra $5 for BDs that also include the wholly unnecessary DVD. Not doing so is why we can't buy every new movie on UHD BD.

Not catering to the elite in this case is just the wrong way to go. Provide the best. Let those who can enjoy it do so. Those who don't notice will be no worse off.
 
I don't think HDR has the easy selling points that 4k does. Try explaining greater dynamic range to your average Joe. Its much easier to advertise 4k. You just have to say, "look how sharp it is"!

That said I'd rather have an HDR TV vs a 4k one. At this point Blueray on most TV's looks phenomenal. Only thing I notice is the sometimes lack of Dynamic range and color.

Music did cater to the elite. It was called SACD and it failed horribly much like laserdisc did. Sometimes quantity trumps quality. It is sad but a reality of the consumer world we live in. The transition from VHS to DVD largely was a success not due to image quality but the features and capabilities DVD provided. No longer needing to rewind a tape or skip to any section quickly. It was features that made the experience 100x more enjoyable vs the digital quality or resolution. Its one of the concepts in user experience design and why the subject is so important today. Users want a positive experience and the transition from analog to digital provided many user experience advancements. Quality is rarely considered a user experience factor.

MP3's succeeded not because people no longer wanted the quality but because people could download them on the internet and store a lot of them in a small space. MP3s were the gateway into convenient digital music and honestly the quality only mattered little to the new world of how people could get and consume music. The audiophile in me still prefers Vinyl but I tend to listen to music through iTunes long before I walk over and swap out a record every few minutes. Can't listen to my vinyl collection at work or while exercising either. I love the quality of music and used to listen to SACDs with a former boss of mine but honestly even for me the simplicity of MP3 won me over in the end.
