Dolby Vision now possible through MP4 Mux.

[V.Florin]

I have the Philips HDMI Sync Box between the tv and both players (Sony and Zidoo). The Sync Box synchronizes the lights of different Philips hue products to the image on the screen.

The Sync Box works with Dolby Vision only if it’s player-led (LLDV). It doesn’t work with TV-led Dolby Vision, unless I switch on the “Dolby Vision Enhanced compatibility” option inside the Sync Box settings. This option basically forces the player to switch to LLDV and then the lights work. So if the Hue lights sync without the DV enhanced compatibility option checked - it’s player-led DV. If they don’t work - it’s TV-led DV.

Hello,
Can you explain me (step by step) how you connect each device with the other one?
I wish to make a sync hue lights also.

I'm trying to get a brightness plot of this:

HDR format :
Dolby Vision, Version 1.0, dvhe.08.07, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

I've used various versions of Dovi Scripts with various errors.

Is it not possible to plot Profile 8 Level 7 DV? I do not see Level 7 in DoVi_Scripts_1.9.2_MKV workflow 6-2-3/4/5.

Any guidance to plot said DV would be great.

Also, where would the plots be stored? In the same folder as the source MKV/MP4 or?

Thanks!

6-2-3 can plot any dv file.
It sounds like you're missing tools (check your pm). The default output path is the dovi_script folder so the graph picture will be in there.

Thank you ever so much! it worked straight away!

Quick question:

Why isn't converting HDR10+ to Dolby Vision not recommended? Is this because the Dolby Algorithm is just better or are there other reasons?

Because you can now supply an HDR10+ file to the 3-1 process which will provide you with a Dolby Vision file using Dolby's latest algorithm and the original HDR10+ scene cuts, which is better.

The main reason is the average pq metadata, Dolby Vision is very different.
HDR10plus and madvr generation have very dynamic avg_pq numbers compared to DV which can cause some brightness fluctuation between shots.

Thanks. This is kind of what I was afraid of. There's really no way (for a normal person like myself) to tell whether a "hybrid" encode was done properly. I'm basically seeing ONLY hybrid files for all new streaming shows being encoded. These encoders are not posting the original profile 5 sources which is absolutely infuriating. I rather just grab P5 versions so that I know that it has the correct brightness. Why in the world are people not doing this? What changed? Is there any possible way to like "reverse engineer" these files to split back out the p5 stream? or is that impossible?

I stopped grabbing p8 hybrids earlier this year when I learned all of this. There is really only one uploader that I trust.

Is there any way that you could share which uploader you trust? Not sure of the rules here or if you can even send private messages. Feel free to decline if I am crossing a line.

But yea. I just don't understand it.....uploaders who used to upload source P5 materials just randomly all switched to uploading P8 files. I have no idea what happened. I legit cannot find any P5 files of recent streamed shows. They're literally all P8 lol. If they know that P8 files are bad form....then why do they keep doing it?

Most dv release groups I know stop releasing P5. There's a Chinese group still releases itunes P5, but I don't know if they were the original uploader or they just modified someone else. And I'm also looking for more trusted release group, their releases sometimes just broke, frame rate slightly off, etc.

Indiana.Jones.and.the.Dial.of.Destiny.2023.2160p.iTunes.WEB-DL.DDP.7.1.Atmos.DV.H.265-DreamHD

I really hope groups could upload P5 and P8.1 separately, instead of just hybrid them. I think with the increase of brightness in screen panel, brightness mapping in RPU is becoming less important. The 11.5 bit color of P5 and 4:2:2 sampling of P7 seems more beneficial.

1. What is the best alternative for watching FEL content on non FEL supported devices.
2. Is it possible to generate HDR10+ plus data using official scene cuts.

Thank you.

1. dovi baker + x265 with decent encode settings ( at least CRF-17 slow preset)
2- no

I'm trying the DoViBaker workflow, is it normal that with Ryzen 7 7840HS + RTX 4060 the conversion speed is about 2.4 fps (0.1x) only?

I don't know.
With my i9 13900ks + rtx3070, it's slightly slower than a regular HDR encode, about 6-7fps at slow preset.

Alternatively, you can always buy a good UHD BD player and your favourite (FEL) movies on disc. Time is money, no?
