My Zidoo Z9X....

Please, you mean what? If I can ask. That it can be converted to DVD fab or makemkv

 

with dvdFab and MakeMKV yes you transform your Bluray into MEL (8.1 with makemkv)

 

Please could I ask for instructions.

 

You don't know if DVDFab or MakeMKV works to create a mkv file from a UHD BD with DV FEL.
We are unable to check those mkv because none of the device that are "dual layer FEL capable" are able to play those mkv in DV.

There is a very interesting post from RESET_9999 here : https://www.makemkv.com/forum/viewtopic.php?p=104113#p104113
If you compare C8-fel / C8-p8-rpu and x700-FEL / x700-p8-rpu you can clearly see that the EL layer is not displayed in the single layer "BL+EL+RPU"
For me this tends to demonstrate that all the single layer mkv files made from the UHD BD with FEL DV are false DV.

 

As you say, it is possible.

the only thing we know for sure is the ISO DV with a Chinoppo

 

Hello,
Yesterday I managed to manually scrape most of my unmatched movies and create cascading collections with the Zidoo Control Center, that's cool.
I created a folder on my HD connected to USB on my Z10PRO where I put some posters that I can recover with the remote control but still not with the Zidoo Control Center, the same for the name of the Directors that I can not always change with the ZCC : it keeps the name of a modified former Director. How to explain these problems ?

It's weird, 2 films that I cannot manually scrape: the last Sam MENDES with or without "(2019)" and the Costa Gavras films from 1969, the same, with or without "(1969)", I finally succeeded with ZCC.
2 more questions concerning the ZCC:
- how to rename a collection? (I misspelled a collection, I used the "disband" function and recreated a well-spelled collection because not found the "rename" function with the remote control or ZCC)
- how to permanently delete a collection because it still appears in the list
Thank you for your help.

and @oliverQc, thank you again for your super well explained tutorials!

 

I confirm, however.

With makemkv I transform Bluray UHD FEL into mkv MEL, and I manage to extract the RPU (the Dolby vision metadata are in) and re-encode the MKV MEL with x265 with the RPU which gives me an MKV MEL 8.1 x265 DoVi encoding.

Indeed I do not have the EL layer, so it is not a Dolby 7 but a Dolby 8. There are several Dolby profiles. So this is not a FALSE DV. As a reminder, the BL layer contains the video with the HDR, the EL layer contains the DV enhancement which is in the RPU.

As long as we manage to keep or extract the RPU we have the DV metadata.

The bluray DV 7 FEL was made because the bluray DV players have to simplify 2 decoders, one for the BL and one for the EL + RPU, which 'remix' everything on output.

This is not the case for Streaming Movies for example (netflix, Prime) and that's why there is only a BL + RPU layer for them, but they are all the same DV .

In the operation of DV according to Dolby this has an impact on 12bits TV matrixes, which is the case for Studio monitors. (rise to 10,000 nits)

We our TVs are in 10 bits.

Hello,
I would like to come back to my post above.
I created cascading collections with the Zidoo Control Center because I couldn't do it with the remote control (Iron Man collection, Thor collection, etc .., in Marvel collection for example).
BUT when I click on a collection in Marvel collection it says "There is no poster in the collection, we will automatically exit the interface". So cascading collections don't work. I can only have one collection and all the movies in it.
Is there a way to fix the problem ?

Moreover, when I want to access to some collections with ZCC, I am asked for a password although I have not created a password (I believe it's the cascading collections only).
What is this password ?

Finally, I am in v6.0.90_G (after a 1st update in v6.0.66_G), I do not know the version of my HT4 which is displayed only 4.0 How do I know the version of my HT4, how to update, would that solve the problem?

Thank you for your help.

 

Exemple with Saving Private Ryan (1998) FEL - 5.80 Mb/s (https://forum.blu-ray.com/showthread.php?p=12116287#post12116287)

The BD UHD is composed by 2 streams
MPEG-H HEVC Video 52120 kbps 2160p / 23.976 fps / 16:9 / Main 10 Profile 5.1 High / 4:2:0 / 10 bits / HDR / BT.2020 /
* MPEG-H HEVC Video 5798 kbps 1080p / 23.976 fps / 16:9 / Main 10 Profile 5.1 High / 4:2:0 / 10 bits / Dolby Vision / BT.2020 /

Here's the HDR10 video stream 2160p


Here's the EL video stream 1080p which contains the metadata (RPU)

Ok. So makeMKV transform a FEL video stream into a MEL video stream and extract RPU to output a BL+MEL+RPU mkv file.

from: https://professional.dolby.com/site...olby_vision_uhd_bluray_authoring_workflow.pdf

In MEL DV the EL video stream is empty, and the second stream contain only RPU.

So, what happen to the EL video stream when makeMKV transform it into BL +MEL+RPU ????

 

So, what happen to tle EL serves you in Transport Stream, the 2 layers are 'muxer' but for improvement what matters is your RPU metadata.
Otherwise transfer the RPU from the EL layer and you'll see what happens (BL + EL).
Makemkv does not extract the RPU (that's me doing it for my x265 encodes)
If your EL layer contained crucial data it would be UHD.
This is not the principle of Dolby.
Have you looked at the link I gave you. The director of Dolby explains very well how dolby vision works and its philosophy.

 

Here is the Dolby Vision process


I suggest you to look at the Dolby Vision patent and you will understand that the EL layer is not only here to transport the RPU metadata. The EL layer is data.
https://patents.google.com/patent/US10701399B2/en?q=dolby+vision&oq=dolby+vision

Where is that stream in your mkv ?

 

know very well how Dolby Vision and its Process work, this is why I confirm to you that you do not lose anything with the transformation of FEL into MEL, but I should have specified because apparently there is a need in this conversation, you do not lose anything that is visibly impactful.

In addition Makemkv merges EL and BL layers, the difference of MEL and FEL and the separation of '2' layers

The FEL I repeat it allows to go up to + of 4000 nits and personally I do not care because my eyes would not support it, and as the TV manufacturers must think of us our oled go up around 1000 nits.

So if you have bioionic eyes and post production screens in fact stay on the bluray Fel (and especially not buy the bluray mel) and in this case the Zidoo is not made for you, you have to buy a blu-ray turntable .

I'm not trying to make you change your mind, you have yours and I have mine.

I do enough encoding and mastering to stay comfortable in what I think, and the results of my encoding confirms me therein

cordially

 

Funny ...
The 1080p EL is merged inside the 2160p BL ... and so, at the end, it doesn't even appear ... it is convenient !!

For your knowledge, i started to make Dolby Vision files in mp4 in 2019
Here's one of my first mp4 files

well this will be my last debate post with you:
Your mp4 is not real Dolby Vision encode, because if the Rpu isn't ripped and re-encoded it can't be real Dolby Vision, you should know that from all the discussions you've had before.
This is the gluing of the EL + RPU layer on the encoding of the BL track.
Good continuation
For info in the encoding data:
VES muxing with Dolby Vision RPU file successful in x265

 

beautifull

 

Damn you make me laugh so loud
What an expert in Dolby Vision !!!

Ok, you can find the method i use, and most of the guys who make mp4 too, to make any mp4 Dolby Vision without any re-encoding on page 36 on the makeMKV forum: https://www.makemkv.com/forum/viewtopic.php?p=76820#p76820
You should urgently make a post on this forum to tell us that we are all doing false Dolby Vision.

 

There is a new beta (0.98) ?

 

Hello afss,

Not just tests to give feedback to Zidoo, the subject to discuss is here,

http://forum.zidoo.tv/index.php?thr...issues-while-streaming-from-nas.84784/page-13

You can ask to have it if you have SMB problems

See you

 

got it, thanks !

 

I am also waiting for the Dune HD VISION series .. may turn out to be a better and more stable equipment than Zidoo

In Z9X I have such a problem that if at least one movie does not open - a black screen, you have to wait longer but no other movie will open I have to restart the Z9X ...
