Dolby Vision now possible through MP4 Mux.

[RESET_9999]

the UHD rip files made with MakeMKV in Dolby Vision 7.06 FEL/MEL?
This kind of DV files, which kind of CM version use?

If this is what you are asking, almost all the movies are done in CMV2.9 and I don't understand why because the CMV4.X L1 generation is VERY different than CMV2.9 L1 generation. CMV4.X is supposed to be improved compared to CMV2.9.

Well well.. is the v2.9 plot from measurements or an actual title's metadata?
As you can see, the minimum average is 10 nits in v4.x.

If you look at most titles nowadays, they also all have 10 nits min average.
It might not mean anything, but it's possible grades are done in v4.x and distribution uses the 2.9 compatible version of the grade.

It would be useful to look at the XML from a CMv4.0 grade that was exported to CMv2.9.

This is 2.9 and 4.0 plot from resolve measurements. Not actual titles metadata.

But you are right. The new Jurassic world dominion, says CMV2.9 but min avg is 10nits.
I noticed too the min difference and most of the 2.9 movies I checked so far have min 2.5nits.

I did and L1 is the same.
The difference is when you set the resolve project to CMV2.9.

Almost every title released in 2021 has 10 nits minimum average, at least those I have data on.
I checked one from end of 2020 and it's 2.5 nits.

I did and L1 is the same.
The difference is when you set the resolve project to CMV2.9.

So the engine for CMv4.0 measures differently, and has different valid L1 specifications.

I wouldn't be surprised if grading is being done in 4.0 but not distribution.
It's pretty clear that devices supporting CMv4.0 are still pretty uncommon, with the exception of TVs.

[RESET_9999]

right, most titles i checked are older one

Hi Reset! First of all, thanks for all your time and effort maintaining these tools and educating the forum.

I would also like to join in thanking RESET_9999 for his time and effort!!!
Really appreciate everything you’ve done and do.

And I am still struggling with my mkv to mp4 conversion)

you're welcome!

Did you try the latest version (1.5.2)?

[lexyz]

Wow, so your TV only supports LLDV but still has the newest CMV4.X version of DV.

I don't think it has CMv4
But does it matter with Player-led mode, hm?
If player supports CMv4 it should output DV with all CMv4 processing.

Ok, thanks for your answer RESET_9999.

Well, then, if a mkv file uses CMv4.0, a device that only supports CMv2.9 couldn't process all the improvements of the EL layer, only the ones compatible with the CMv2.9. So that, the picture looks worse than it is, loosing all the improvements coded in L3/L8. That's right?

And a final question, the difference in image quality between a full process with CM4.0 source and a CMv4.0 source playingback compatible CMv2.9 in a device that only supports v2.9 is remarkable or subtle?

you can try the ATV fake p5 version in your internal tv player. It worked for other Sony owners

No, it would not look worse because L1 is the same.
L8 is just an improved(i suppose) version of L2 and in the end, shouldn't really look different even though each metadata works differently than L2.
The point of trim passes is that the movie looks roughly the same on every TV regardless of its capabilities.

Thanks again for your clear answer.
I was wondering if there's an other concept/compatibility to be aware to asure a correct playback of DV content

Hi DonaldFaQ .
I love your tools also. I usually use DDVT_DEMUXER to fix different cropped RPU vs Video. Especially when the mp4muxer muxed with mismatch rpu pixels range, the video played will be quenched upside down. https://github.com/DolbyLaboratories/dl ... e/issues/7

The last time i use 0.43, I can't got mp4 from mkv with DDVT_MKVTOMP4 properly
Still use mkvcleaver to extract and remux with Dolby mp4remux

BTW, I just got DV 7 video.
It is john wick 2014. Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible
The tv doesn't like with DV7 mp4 container, and the mp4muxer doesn't seem support DV7 also.
Times to use tools...to get DV8.1 or DV 8 HLG

I use RESET_9999 Dovi_Script and DonaldFaq Dovi_tool to convert to DV8 and remuxit with mp4muxer from Dolby github.
Question for RESET_9999:
I just use Dovi_Script 1.5.2, and choose path 4-5-2, and installed phyton with it necessaries.

Looks like it want copy to c:, it needs administrator since copy to main folder. why cant be temp folder instead.

Question for DonaldFaq:
1. If the DV7 mkv extracted using DDVT_DEMUXER with crop off by default. i got rpu.bin that different range (rpu has 280x) as video range (0px)
so i got restarted again with DDVT_DEMUXER, crop on right?
2. When i got the rpu.bin it should be same folder as input mkv right, by using DDVT_INJECTOR to get mkv DV8, right?
3. What the best for budget DV TV: DV 8.1 or DV 8 HLG format from DV7 mkv.


Regards both of you. Thank you for the tools.
