Dolby Vision now possible through MP4 Mux.

so here are some comparisons. Pitch black room without any light, OLED TV, Camera settings locked, Tripod, and Bluetooth triggering.

Dual-layer FEL untouched VS Dual-layer MEL converted
https://screenshotcomparison.com/comparison/6565

the untouched FEL is brighter & has more punch, no doubt. But I think this is normal because I'm seeing the same kind(if not more) of difference when I compare the Spears and Munsil FEL & MEL

Spears and Munsil dual-layer FEL untouched VS Spears and Munsil dual-layer MEL untouched
https://screenshotcomparison.com/comparison/6564

Dual-layer MEL untouched VS Single-layer MEL (el+RPU) untouched
https://screenshotcomparison.com/comparison/6566

also from the bluray discs I inspected, FEL DV hevc stream is the actual movie with a white/grey tint on it while MEL DV is just a static white/grey image.
We still can see the video in the MEL conversion so that could be the reason why it doesn't play on the x700. I can add some random MEL track to any HDR10 hevc stream and it will still play in DV (single or dual layer). with some flickering but it triggers DV.

I also believe that this is probably the expected behavior. When FEL is processed correctly, it's produces a 12bit picture whereas MEL is only capable of 10bit. Even though we don't have 12bit displays, a 12bit stream downsampled to 10bit will still look different than a native 10bit(MEL) stream. A picture and picture comparison of the original FEL vs converted MEL may not then a be a good way of determining whether the method is working. One thing you can potentially try is since the S&M disc contains a demo that's provided in both FEL and MEl, convert the FEL to MEL and then compare it to the provided untouched MEL.

@yusesope
Hello, first of all thank you for your script and your involvement.
So I followed your procedure with the software and script made available.
I tackled MIDWAY Bluray -UHD fr.
For information I have a Panasonic HZ1500 Tv (I test the Dv player on the internal player).
I get an mp4 (without audio track because it is dts-hd), in 8 Dv profile which is read without problem by the TV.
Your procedure works perfectly.

On the other hand when I use TsMuxeR (version given in your procedure w64-nightly-2020-09-20--02-24-10) to integrate the audio tracks and pgs, TsMuxeR changes me the Dv 8 profile into Dv 7 profile, which him does not pass on my Tv, and therefore the video is read in HDR PQ.

Amazing comparison @RESET_9999 thanks

[yusesope]

Great work as always.

also from the bluray discs I inspected, FEL DV hevc stream is the actual movie with a white/grey tint on it while MEL DV is just a static white/grey image. We still can see the video in the MEL conversion so that could be the reason why it doesn't play on the x700.

There are multiple reasons why the FEL structure is intact in my MEL files.
This is not the important thing.
What matters, in my opinion, are the NALu RPU. Imagine the latter as an orchestra conductor. With the right changes I can explain to the Decoder that it does not have to start a second decoding session (as happens in FEL files) but to use "a static image" as substrate (as happens with MEL files) regardless of the presence of FEL data.
This is the goal.

Guys, please note that I don't work for Dolby and I don't have access to any documentation.
All this is the result of a logical analysis shared between me, myself and I.
There is no guarantee that the process will be correct but if it were completely wrong the film would not start on devices like the FireStick 4K (able to read only MEL) and a BD player would not play it (with the help of the right container) without color defects (
and reproducing the same behavior that exists between an original FEL and MEL file)!
Also, I think FireStick owners are okay with anything compared to a full BLACK screen !

...I can add some random MEL track to any HDR10 hevc stream and it will still play in DV (single or dual layer). with some flickering but it triggers DV...

True!
The tricky part is to generate glitch-free files on devices that cannot read the original (FEL) files.
Result that cannot be achieved with random data !

I also believe that this is probably the expected behavior. When FEL is processed correctly, it's produces a 12bit picture whereas MEL is only capable of 10bit. Even though we don't have 12bit displays, a 12bit stream downsampled to 10bit will still look different than a native 10bit(MEL) stream. A picture and picture comparison of the original FEL vs converted MEL may not then a be a good way of determining whether the method is working. One thing you can potentially try is since the S&M disc contains a demo that's provided in both FEL and MEl, convert the FEL to MEL and then compare it to the provided untouched MEL.

I agree with every single word especially the blue part.
I don't want to take advantage of your kindness @RESET_9999!
Also keep in mind that my RPUs carry more information than those normally found in MEL streams.
Maybe the result could be in favor of the converted MEL file over the original MEL.
Or it could be a complete disaster...

EDIT
Pure personal judgment.
I like the MEL frame more than the FEL frame .

[ghostshadow]

hello yusesope
j'ai utilisé ta méthode pour creer un mp4 DV profil 8
Il passe très bien avec le lecteur interne de ma Tv panasonic. Par contre j'ai pas pu intégrer les pistes audio qui sont en dts-hd
J'ai essayé de faire un .ts mais le profil DV change en profil 7 et la il est pas lut en Dolby vision

[RESET_9999]

keep in mind that those pictures are amplifying the difference... the clipping here is introduced by the camera, there is no clipping in real life.
I'm sure you would say that you prefer the FEL one if you saw it in real life. Not a big difference but i can tell fel is more vibrant.

I'm not very familiar with your tools because my player can play dual layer DV so i dont really know how to convert/extract it.
If someone can upload a small MEL conversion sample of that spears and munsil disc, I can compare it to the original MEL file.

I had imagined it. I trust your judgment.

This hurts my little heart

I have encountered several difficulties in making the cut.
Hope it works .
HERE it is.

Bonjour, mon ami!
J'ai etudie le français a l'ecole (quand j'avais dix ans) et je ne me souviens (pas???) de rien .
Le conseil est de rester avec le conteneur mp4.
Ta (votre??) televiseur ne peut pas envoyer le dts-hd avec le port HDMI et, dans le cas des speakers internes, dts-hd est lu comme dts (core uniquement).
La prochaine fois, tu dois ecrire en anglais sinon ils pensent au stereotype du français que ne veut pas parler anglais

Sorry I made a mistake .
So my mp4 has no soundtrack than the video track.
If I use TsMuxeR to mux 'BL_EL_RPU.hevc' which is in dv 8 profile with Dts audio tracks, TsMuxer switches me back to dv 7 profile, and it is read in HDR PQ and not in Dolby Vision.

Good evening yusesope, how do you get the RPU out of the EL? it is to be able to encode afterwards in x265
thank you

[RESET_9999]

yep, it looks like @yusesope fel to mel conversions are done properly. Great job man, you are truly a genius.

https://screenshotcomparison.com/comparison/6581


if you're looking for a new project, I would love an RPU parser(supported by x265.exe) just like the HDR10+ parser does so I can encode uhd-BD to true profile 5 full range.

True profile 5, that's what I am waiting for! I appreciate all the work you have done testing and comparing the profiles. Thank you!
