I don't know why you are mentioning the optimizer and DV since we are talking strictly about DV and the video with Vincent.

I'm going to hold off purchase for now. Hopefully the right people get this issue to Panasonic and something gets corrected. My main purpose is UHD/BD playback and although HDR playback sounds awesome I really don't want to shell out $500 if DV playback is now going to be an issue.

Diddums. I didn't say it WAS applied to DV, I just find it ironic (look it up) that while the Optimiser is streets ahead of any other in-house mapping system the player's own usage of DV is clipped and blown out, with no way to actually alter it.

And yeah, it's not Panny's fault per se (Kris Deering said way back in the thread that the techs told him the same thing) but that doesn't actually change the fact the DV is still fooked on the Panny, does it?

Ooops, completely wrong reply. Not even replying to this forum.

Well, I guess I was accidentally responding to you as I wrongly post my response (it’s supposed to be for a different forum), but yes the DV on the Panny is messed up.

Quick question - Can the 820 display the detailed metadata info of the disc you're watching (like the UB9000), or is that feature locked out on this particular model?

And tangentially related to that. Is there a list somewhere of all UHD discs mastered to 4000 nits? Ta.

Locked out.

Not really, there's a metadata list out there but it stopped getting updates a while ago (I've been doing my own). General rule of thumb is that stuff from Disney, Paramount, Fox and Universal are rigidly mastered to 1000 nits peak on disc (with the earliest Fox titles at 1100 nits), Lionsgate can be either 1000 or 4000, while most Sony and Warners discs are mastered with 4000-nit mastering display metadata, though Warners have produced a few 1000-nit encodes recently.

BUT it's worth repeating that most Warners joints don't usually get anywhere near 4000 nits for actual peak brightness, a handful of exceptions aside, unlike Sony discs which are often hotter than the surface of the sun (note: hyperbole). I mean, Labyrinth is 4390 nits MaxCLL and 1327 nits MaxFALL, the peak brightness is one thing but average brightness being that high is just stupid, it's pushing it far too brightly for my liking and Labyrinth is not alone in that respect in the Sony UHD catalogue.

Thanks for your reply. It's a pity it's only available at one UK retailer. They have their website under maintenance right now but I'll check tomorrow if they ship to Spain, my guess is they don't.
I have some English neighbors I get on well with (no other spanish neighbor in the building speaks English) who go to the UK from time to time but we are not actually friends like to ask them for this favor.
The UK Panasonic outlet doesn't ship to Spain. Living in this country and try to get an specific consumer electronics component makes one feel like living in a third world country.

Thanks for the info. That's the one that suits me, it has HCX processor, HDR Optimizer and two HDMI outs. That's the one I'll get, not right now as I'm flat broke (as usual) but May is around the corner and that's when I get an extra Summer wage that will go to the Panasonic DP-UB424EGK.

Thanks Geoff.

Geoff...do you think the issue is enough of one to favour HDR10 with the optimiser and turn DV off?

[Bigbro]

can somebody help me out. When using the optimizer do I use digital tone mapping within my LG 77c8 or not. I tried both. At first glance using them together made the screen brighter. Using only the HDR Optimizer left it darker. What is your opinion?

[Robert Zohn]

@Bigbro, I suggest leaving the dynamic HDR tone mapping enabled on your C8 and set the Panasonic BD player's HDR Optimizer set to "OLED TV" and of course set to HDR Optimizer on.

You will undoubtedly get better highlight retention with HDR10 and the Optimiser but this can create a touch of posterisation, and with some DV discs the HDR10 layer isn't encoded as well as it can be. It's not a question that has an outright yes/no answer, if the Panny was my only means of DV playback then I'd still use it for certain titles (thankfully it's not my only means of DV playback though).

[elwaylite]

DV stays turned off on all my devices, and if a device forces me to use DV (like say an app on a streamer), I just dont use it for that app. Screw DV.

If it's suppose to be a Dolby issue, then how do one explain the differences in the DV output between the Oppo and the Panny? Since the Oppo DV seems fine, then i'm incline to say it's more of a Panny issue than dolby.

I bought the player for its DV capability, as well as for the optimiser...so I’m a little annoyed at this flaw. Hope it gets addressed.
Other apps that use DV I can watch through the television’s own apps - so that’s not such an issue for me.

If Panny is the odd one out, yes it’s Panny’s fault. But everybody got DV wrong except for Oppo which logic dictates that Oppo got it right accidentally as it is unfathomable to me that nobody else can get it right

One should try a Phillips, LG, Pioneer DV capable player to compare DV brightness compared to HDR10 if possible.

Panasonic doesn’t represent everyone else other then a Oppo that has a DV capable player as you are arguing.

Previously you were trying to blame Dolby’s certification of processing Dolby Vision bitstream profilie of a player, but if you don’t have a player using the same FW at the time it was tested, how do you know the current version people observed this issue is not at fault?

Need to troubleshoot with an open mind.

I have had zero issues with UHD DV playback on my LG UP970. Last time I had read comparable reviews with shootout test between this player and OPPO 203 there was no discernible difference from what I had read.
