v1.2.25, v1.2.25_G Beta version for Z9X 8K

I am anxious to test this one: 1. Added SDR.BT2020 output

 

At the moment you have to manually select it in the HDR10 portion of the Advanced HDR menu, but it plays SDR.2020 natively then which is a little counterintuitive - hopefully by OTA release, it will be automatic.

 

New FW is always good and I hope the release for the other devices will not be long in coming, but why has one of the main problems, namely the small DV stuttering that still exists, not been fixed? It is demonstrably still there.

 

Not that any of us have seen.

 

I will send you a link to 2 mobile phone videos with stuttering after 10 seconds via PM, but I have also had a film with irregular stuttering, now I am running the player in LLDV only again...

 

Thanks Mark! Do you know why only HDR10 has this option (what about HDR10+ and DV)? (maybe for now?)

Please, would it be possible also to add this on the SDR content output mode, in order to standardize all outputs as BT2020?

 

This is a preliminary release so is yet to be finalised but it's more to do with playing SDR.2020 content natively rather than conversion to SDR.2020 since VS10 doesn't support it.

 

I am unable to replicate.

 

This is still my problem. After pausing and resuming playback later, the stuttering starts after a few seconds. LLDV doesn't always help, because now and then there are still DV files that start to stutter a little.
I can hardly imagine that this problem is so rare. @Bill-Z9X will confirm this with the example videos.

 

I saw stuttering in 4k DV files also...but I have to check more..if it is just those few files..or more.

Dolby Vision is:

Profile 4 MEL
Profile 4 FEL
Profile 5
Profile 7 MEL
Profile 7 FEL
Profile 8
Profile 9
Profile 10
Profile 20

You have CMv2.9
You have CMv4.0

You have TV Led

You have Player Led

You have homebrew Profile 8 Hybrids from an HDR10 file cobbled together with an RPU from a completely different Profile 5 file.

Some know how to do it, some don't.

You have Profile 8 produced from Profile 7.

Some know how to do it, some don't.

You have Profile 8 encodes produced from a Profile 7 file.

Some know how to do it, some don't.

And several other variations.


We don't know what grubby corner of the internet users' files came from and via what circuitous route they found themselves there.
And that's just the tip of the iceberg.

This is why I continually say if we can't replicate an issue, we can't fix it.

@Markswift2003 I understand you, of course, but you don't have to freak out right away. We are here to give our feedback so that you can deliver a satisfactory product.

Small example of my personal problem with the current Netflix series Dept. Q. And no I didn't get the series from a dark dingy corner.

Here is the video data, which currently (not always but from time to time) shows small stutters:

Mostly exactly with this DV profile

 

I enjoy a good freak out every so often. And it's the weekend, so when better?

All I can tell you from that is that it's Profile 8 and it's from Netflix, so yes, of course it came from a dark corner of the Internet.*

Because Netflix stream in Profile 5 for Dolby Vision in IPT colour space, and this file is Profile 8 in BT.2020 with P3 primaries, it's a hybrid.

It's cobbled together by somebody who thought it was a good idea to take an HDR10 Netflix rip which is already re-encoded by Netflix themselves from the HDR10 deliverable from the Post House and then stitch the RPU from the Profile 5 stream while converting that RPU to Profile 8 (dead easy to get right and dead easy to get wrong).

Bottom line - why?? Why bother with it?? If you want Dolby Vision use the Profile 5 stream. If you want HDR10, use HDR10 stream. Why crowbar them together?

People who do this are, in my opinion, a small step above the idiots who think they can "regrade" a movie in their bedroom - don't even get me started on those half wits!

I mean, whoever buggered about with it might have made a decent job of it. But they might not. My advice is always always avoid hybrids - if you insist on downloading them then use a tool like DVTool to remove the Dolby Vision element and be happy with the original HDR10 file.



* and believe me I'm absolutely not casting any aspersions here

 

I pay for several streaming services such as Netflix, Prime etc. and for this reason I don't have any major problems with my conscience. Making a copy of a blue ray is also not legitimate because you are breaking copy protection.
Basically, these media players from the beginning are made for non-legitimate content and that's no secret. There are hardly any people who only play their home videos or TV programmes recorded from the TV on them.
There are no problems with these recordings and we can say that the media player is perfect.

 

This is nothing to do with taking any moral high ground - I'm sure none of us can occupy such exalted territory - It's about separating the wheat from the chaff - there's so much crap out there you have to be careful where you tread.

 

I agree with you, but these are the exact same videos that Zidoo worked for over 2 months to fix the stuttering, it just wasn't completely fixed unfortunately. I don't understand why has this suddenly become a problem for you.

I certainly won't bother you with this problem again, but I'm sure others will come and ask.

As I said, I'm done with all the problems. I've just realised that it's actually stuttering in the LLDV too, so I'm going to get a Realtek 1619 DR player and use it until then.

 

That was a very different issue and happened with compliant DV files.

This certainly hasn't "suddenly become a problem for" me - in fact it has never been a problem for me because I avoid Hybrids like The Plague.

There are probably more and I probably moaned about Hybrids on AVS too even though I steer clear of there as much as possible...

 

However, this problem only occurs when you pause the video. If you exit playback for a moment and restart the video from where you left off, the problem does not occur again.

 

I don't know if I make this update, Currently no bugs ?? Thank you for your answers.

 

Only you can decide to update or not, but for me personally, it seems a solid r/c, so far (not withstanding the remaining bugs).
