GH5 V-Log LUT

Has Panasonic released a V-Log to Rec 709 LUT? Not looking for user creations here. Looking for one supplied directly from Panasonic.
 
The more interesting question would be:

When does Panasonic release LUT(s) for VLog to BT.2020 color space?

Well, not to be pedantic, but that's kind of moot as the industry has pretty much skipped SDR with wider gamut straight to HDR with wider gamut. So the more relevant question is will they provide V-LOG to HDR10, HDR10+, Dolby, etc. LUTs. My guess is, no, as HDR workflows seem to be gelling around not working in display color spaces. (ACES, RCM, etc.)
 
That is a good question. Is the GH5 series even capable of Rec.2020?.

V-LOG-L uses V-GAMUT which is even bigger than Rec2020.

@TheTrickster - on an unrelated note and without wanting to hijack the thread, I noticed your a diver (profile pic) and based in Spain,
any recommendations on decent scuba sites over there? We go to La Manga every year to dive from Cabo de Palos on the marine park,
best diving I've found in Europe, really nice surprise dropping in there for the first time.
Used to work globally as a resort videographer for a good few years, Amphibico/Sony TRV950, cant imagine how much better the images acquisition has got since then with the GH series and a nice housing :)
 
Many users prefer HLG to VLog-L, & it comes free with the GH5. Haven’t tried it myself because I mostly handoff my footage, & don’t want to to get to deep into explaining the HLG workflow to Post.

HLG is a quick-delivery profile. It is not suited for grading or any serious color correction. I‘d go for V-Log over HLG for most of my use cases.
 
Thanks again, Trickster.

Though the chart does reinforce the question...where's the official V-Log to Rec. 2020 LUT? Or perhaps a V-Log to P3 LUT?

Effectively, there is no use for it. There is no practical way to distribute and consume wide gamut SDR. When people speak of 2020, it is usually only in the context of the color gamut, which has been incorporated into HLG, HDR-10, etc.

Have to strongly disagree with you I'm afraid. HLG uses more of the 10 bit space AND has more accurate tonal density than V-LogL. It has been my default profile since it was released in camera and I've just wrapped principal photography on a feature film shot entirely in HLG with the GH5S :) Its grades BEAUTIFULLY!

Thumb drive won't suffice? I mean, HDR is an option for UHD, Rec 2020 is a requirement.
The tldr; version is that the entirety of rec.2020 is an SDR standard that for all practical purposes has never been adopted. One part of it, the color gamut, has become the basis for other standards, like HDR-10, that *are* being adopted.

The even shorter version is that you will struggle to find any SDR display that supports rec.2020.

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?

For now. I get that.

But technology progresses. I'd prefer my clients have a copy of their projects in Rec 2020 color space for that TV they get in five years time that can display 90% or better.
