v1.1.60 Beta version for Z9X 8K/Z30 PRO/Z3000 PRO/UHD8000

Actually, what I am looking for, for my setup is the following:


UI > SDR

SDR > SDR
HLG> VS10 HDR10
HDR10> HDR10
HDR10+> VS10 HDR10
DV HDR10> HDR10
DV HDR10+> VS10 HDR10 (this is where there seems to be a problem currently, as the player is outputting SDR)

 

Ok, the problem is separating DV HDR10 and DV HDR10+ behaviour in relation to VS10.

Because VS10 is a Dolby product (and not Samsung), Dolby Vision takes precedence, so in order to output DV HDR10+ as VS10 HDR10 you also need to output DV HDR10 as VS10 HDR10 - the VS10 engine has to be set for DV, regardless of the status of the base layer.

There is zero benefit from applying VS10 to HDR10+ and not to HDR10. VS10 does not use the HDR10+ dynamic metadata (because it's a Dolby product).

So VS10 HDR10+ is exactly the same as VS10 HDR10.

But because you have HDR10+ options means that your TV supports HDR10+.

You want HDR10 native so why don't you want HDR10+ native too?

 

Thanks Mark, this is very good discussion.

Well, first let's agree there is an issue regarding the way the player handles DV + HDR10+ files, outputting them to SDR. Since I have none of my HDR formats mapped to SDR, something is definitively wrong with the Zidoo firmware algorithm selection for this specific file configuration.

Regarding the benefit of VS10 for HDR10 versus HDR10+, let me share with you my personal experience. I have found that the JVC NZ8 tonemapping does a better job with pure HDR10 signal, then VS10-HDR10 processed signal, but on the other hand, I found the outcome of the VS10 HDR10+ file processing to be much better than the JVC HDR10 tonemapping - I know it sounds weird, but the visual difference is pretty significant - so you are saying VS10 ignores the HDR10+ dinamic metadata e treats the file just like HDR10?

 

It is very interesting!!

Yes, there is definitely a problem with the logic which I will address with the devs when they return - good catch!!

So yes, that's exactly right - VS10 treats HDR10+ exactly the same as HDR10 - it completely ignores the HDR10+ dynamic metadata.

You can also set the JVC to ignore HDR10+ metadata and also if you want you can send your EDID and I can remove HDR10+ from it (which may be the best option - then the Zidoo will not send HDR10+ to the projector).

 

Thanks again Mark, I will download my EDID and reply later on as I get home.

Please, one last question just for me to fully understand the player's behavior - Since Zidoo ignores HDR10+ metadata, why does it allow for a different VS10 configuration for HDR10 versus HDR10+ ? What would be the benefit of configuring it differently for each type of files?

 

Hopefully their is a new update soon for the player "A" start a movie or tv show, SD/HD/UHD makes no difference, It takes its sweet time to start "B" if you pause a movie/tv show SD/HD/UHD makes no difference you come back and press button to play again, screen remains black and will sometimes audio keeps going lags starting a video back up from pause....its not the videos either on my Dune real vision 4k they start stop pause all in correct manner

 

Is there a way for those using G version firmware to adjust DPI? There are some apps which renders in a smaller UI that would appear normal, larger, UI on other Android TV devices. I am using Z9X 8K for reference.

 

Yes exactly, I find it brighter and more detailed. I have done several tests in these months ... An example was the film "All Quiet on the Western Front" on Netflix. Shortly after I tried the bluray of the same film on the zidoo and with the same video settings of the TV, the image was decidedly darker than Netflix, so I deduce that the tone mapping that the TV processes with Netflix is more correct. As soon as I selected "TV-led Bypass Auto" the tone mapping returned to the same as that seen with Netflix. I hope I explained myself. As for the stuttering, I had a similar problem and I solved it with a factory reset. I hope I was helpful.

 

OK, I'll proceed with the purchase!
...But, first, is there any (eager) Forumer able to test the functioning of this double configuration, perhaps doing a (small) review?
Thanks Thanks Thanks

So that you can apply VS10 to HDR10 if you want but still retain pass through for HDR10+ metadata.

 

Was it stuttering specifically related to using DV bypass mode or a more generalized stuttering problem even using lldv or normal tvled?

I ask because I don’t want to factory reset if I don’t have to and others have the problem with bypass stuttering and even mark has a test clip for zidoo to fix the problem so I don’t understand how come you don’t have stuttering using bypass mode now?

What does your setup look like?

 

A question about something I noticed today ( or I was blind before).
I use the new DV auto passthrough. .
Was watching IMAX Aquaman with DV.
When I paused I saw it was TVled but with RGB.
It looked great. So it is not a complained but isn't it normally yuv?

 

got it, thanks!

 

All DV TV LED modes are sent into an RGB 8 bits container. That’s how dolby vision works by design. Player led is yuv.

 

Pretend I didn't say anything. I thought I had solved it and instead I continue to have stutters with all films in Dolby Vision, I have the problem with any Dolby Vision mode I select, nothing changes if I select LLDV or TV-LED or TV-LED Bypass Auto. With films in HDR10 everything is perfect. I'm attaching a video to show you what I mean and what happens to the Denon display. I don't know how to solve this problem!

Ok I never watched anything completely on the z9x 8k yet but I think it’s also not perfect on my side on playback but it seems rare that it stutters in lldv or tvled vs on bypass it’s way more often.

Also, I’m pretty sure now I have the a/v sync still but on dts-hd only and not on truehd.

 

Ah ok. Thank you. I never noticed before. Probably because I didn't look

 

In addition to the occasional stuttering, have you also noticed that there is worse management of the 'motion control'?

 

@Markswift2003
Mark but in your opinion this problem I have, what could it depend on? It only happens with films in Dolby vision, those in SDR and HDR10 are perfect. I use an HDMI cable that goes directly to the TV and the other HDMI cable is connected to the amplifier via the HDMI audio only output. If I disconnect the HDMI cable from the main port of the zidoo and leave the HDMI audio only cable connected, the problem disappears. What could cause the problem? Attached you will find the video of the stutters, watch what happens to the Denon display.

@Markswift2003 , my A/V sync issues with TrueHD are gone like for everybody else it seems but I still have the 150 ms A/V sync issue with DTS HD. I cannot use the passthrough compatibility mode because when I use it, TrueHD is not synced anymore.

It's clear the Zidoo team fixed the A/V sync issue on TrueHD so can you send a request for them to investigate DTS-HD specifically to fix it too? If they could fix it on TrueHD they can for DTS-HD too. I don't know if this affects normal DTS too since I don't have a DTS movie that I would have in mind right now.
