Re: Dolby Vision now possible through MP4 Mux.
PS, to those who generate DV...
I said a couple of times that I selected the mastering display luminance based on the content's actual brightness(measured in 6-2).
I said to use 1000nits MDL if 90%+ of the shots have highlights under 1000nits.
Well, this is not longer the right thing to do because I recently discovered that some players like the Ugoos, Oppo, x700, X800m2 will clip highlights if the content is brighter than the RPU mastering display luminance, regardless of the metadata. So it may not be a good idea after all to use 1000nits MDL even if there are only a few highlights brighter than 1000nits because they will be clipped if your TV is not capable of displaying this brightness.
Interestingly, the Shield, the AppleTV, C2-C1-C9 internal player and Hisense internal player do not have this behavior and will tone map the image correctly without clipping regardless of the MDL (as long as L1 is right). This finally explains the RPU response differences between TV-LED devices that we noticed a long time ago (years ago?).
I did some test files that clearly show what I'm talking about: https://drive.google.com/drive/u/1/fold ... URFcibN6X-
Specifically: ''Dolby Vision 1000nits RPU Harry 2848nits scene P8.mp4''
*** This is about TV-LED. LLDV seems to work properly. Confirmed on oppo, ugoos, C9 C1 C2 Hisense... I no longer have the x700 x800m2 but it is most likely the same as the oppo, they have the same soc

Good to know thanks. Prores it is then.RESET_9999 wrote:Yes, I tested hevc decoding not a long time ago and it still drops frames.
Try the Spears and Munsil demo clip, it drops frames almost instantly with the mkv container. If you remux it to mp4, the SM clip will work but it is still not 100% reliable.

I finally was able to fix my Davinci working with their support and I want to start playing with DV conversions soon. Thanks!

Re: Dolby Vision now possible through MP4 Mux.
So do we have to re-generate to a higher mastering display (based on 6.2 measuremnts) or just edit L6?RESET_9999 wrote: ↑Sun Jan 05, 2025 2:12 amPS, to those who generate DV...

Re: Dolby Vision now possible through MP4 Mux.
If you use a Oppo, X800m2 , x700 or Ugoos and the content has highlights brighter than 1000nits, it should be generated again. L6 is useless.darrrkmanxxx wrote: ↑Sun Jan 05, 2025 12:32 pmSo do we have to re-generate to a higher mastering display (based on 6.2 measuremnts) or just edit L6?

@RESET_9999
I looked for Alien Romulus web rpu in your google drive folder and only saw Alien.Romulus.2024.UHD.BluRay.2160p.TrueHD.Atmos.7.1.DV.HEVC.REMUX-FraMeSToR Retail P7 FEL (cmv4.0 added).bin. Is this file the equivalent of CMV4.0_L3L8L9_transfered.bin? Do we just inject this directly to the bluray mkv file?

The link is private...
Instructions on how to access it are in the Resolve Metadata Generation tutorial comments.

Re: Dolby Vision now possible through MP4 Mux.
@RESET_9999
For devices who can't play P7, what would be the workflow to get the best out of dynamic metadata?
exmaple:
I have one profile 7 remux and a web-dl profile 8, which are compatible in brighntess.
- Extract rpu from web-dl p8
- convert P7 to P8 with dovi_tool
- inject into converted remux
Is that correct?

just convert the P7 rip to P8 with workflow 4-1

thanks, is this the same as with dovi_tool mode 2 from quietvoid?

yes, all the workflows rely on dovi_tool.exe ... there's no other way.

Would it be possible to extract the HDR10plus of lower quality mkv and inject it into its higher quality variant?

Yes, measure both videos if they are the same grade.

RESET_9999 wrote: ↑Fri Dec 27, 2024 2:59 pmNo, madvr generated metadata (3-2) is the worst and not really suited for DV playback. Also, Madvr scene cut detection is not very good. It's quite sensitive to flashes/explosions/fast movement and can sometimes miss obvious scene cuts. The best dv metadata generation is one of the analysis tunings using Davinci Resolve. I prefer the ''balanced tuning'' which is the dovi_scripts default in workflow 3-1Thanks for explaining. How to interpret those? Is the madvr plot the best, because it has the most dynamics?
If I do the madvr measuremnt, I adjust cmv4.0 when I generate from madvr file with dovi_tool ,e.g.
Hello
in your video you said that we should choose most highlights details in resolve but now i see that you prefer balanced. So what is the best ?
