Dolby Vision now possible through MP4 Mux.

Can HDR10+ be converted to DV now?

I want publicly thank @Reset_9999 for his precious help to let me understand and use the basics of this new tool
Thanks a lot also to @quietvoid whose hard work has allowed this to happen.

Am I missing something, or is it not possible to simply re-use an "old" x265 encode and simply inject the rpu of the uhd (makemkv)?
RPU gets generated successfully, also the inject does not abort.
... No matter what settings I try in the end the hevc only shows HDR10 in mediainfo.

So I'm now even more convinced that 1, the dynamic metadata are working properly and 2 , the slight color difference with HDR10 is caused by the LLDV bug (because we can't capture tv-led)
*** appleTV files color issues is not related to this though

1- one of these sample RPU is synced properly and the other is out of sync.
you can see the brightness jump at the 4-5second mark.

2- Remember HDTVTEST Vincent video about tv-led vs player-led ??
well we captured the LLDV signal in PQ of the SM clip, and compared it to the HDR10 BL tonemapped in SDR. The difference is literally the same as in Vincent's video.

What I find funny and not very scientifically thorough is that he only tried one brand, Oppo I believe, and then blamed the results on LLDV instead of trying multiple sources that could do LLDV, like the Sony X800M2 to see if it was the player itself OR LLDV causing the issue. He seemed to jump to conclusions that just because the Oppo caused this, it must mean ALL LLDV sources do this. That’s not sound science based analysis!

I had the Oppo 203 and the Sony X800M2 here shortly after I was the one who discovered this LLDV trick and the Sony was clearly the better device to use for Dolby Vision on otherwise non-Dolby Vision displays and projectors. Oppo had some sort of color bug that resulted in much less saturated colors. I believed and stated at the time that it was most likely due to the same bug that caused its tone mapping to only use Rec709 color gamut even if you chose BT2020 when using its SDR/BT2020 mode. Something to do with the mediatek chip if I recall.

I bet it also has to do with him not inputting custom Dolby Vision data block info like we do now, so the player then maps the signal to the exact specs of the display and/or projector, just as it does with TV-Led. If he didn’t use the right max nits, etc. then it results in improper tone mapping, meaning compression, which could easily have been the cause of these so called “issues”!

LLDV looks absolutely stunning here in my setup using a BenQ LK990 projector, new AppleTV 4K and an HDFury Vertex2 for the LLDV EDID spoof. I just watched Army of the Dead on Netflix last night in DV on my LK990 and it was probably the single best HDR/DV experience I’ve had!!! Pure eye candy with HDR effects that I’ve not seen on a projector before!!!

Well, it is possible that Dolby updated their SDK on the newer players.

Our test was done on the Sony x700 which is pretty old and the result 100% matches those of Vincent. @Manix should be able to compare all his device's LLDV output but he doesnt own the Sony x800m2.
I don't know about the custom Dolby Vision data block info though.

[HarperVision]

Did you see my updated information in my post? Did anyone use custom DV data block info? Also the tone Mapping (compression) as I said could easily have been the cause for these anomalies because when you do player led you have to manually tell the player what the specs are for the display, unlike TV led which gets the raw info from the player and then uses it’s already known specs internally to do the processing.

It doesn’t sound like Vincent did any of this.

do you have a link / more info about that ?
or please tell manix which settings(DV block) exactly to use on the vertex for the Spears and Munsil video. He can capture without the limitation of his CX by using only the Atomos Shogun which has a 3000nits peak brightness and he'll be happy to test anything you wish.

Yes, but this custom block sinc to the tv max
Values cx so yes it’s tone mapping to the CX
Edid sinc,
I can also do it without CX tx0 sinc & check the results.
Or no tv connected but 3000nit monitor and send the correct dv meta

Have you read the dedicated threads at AVS Forum and AVForums? All the info should be in those threads. Search for user Mark Swift as he is the one who deciphered the DV Data block and then based on that, HDFury included the capability to write Custom DV Data.

Here is what the Tab looks like in the Vertex2’s GUI:


I personally use settings that no one else seems to be using or trying for some reason. Maybe they’re afraid to go so extreme or be ridiculed from others saying “that can’t work”, when it actually does AMAZINGLY WELL!!!

I use a 10,000 nit Custom HDR EDID and also the DV Data Block’s Max Luminance at 10,000 nits. This works awesome and presents the least amount of compression (tone mapping) it seems. The image is so clean and detailed and you can see every nuance in dark scenes and the specular highlights are incredible without being blown out, when paired with the right HDR curve in your display/projector. It appears to work best when watching streaming content like last night with Netflix and iTunes movies with DV are amazing. When used with Infuse app on AppleTV with ripped HDR UHD blurays is the pinnacle though. I can’t even tell they’re not native DV!

I have gone back and forth with a DV Data Block between 1,000 nits and 10,000 nits and for some content 1,000 may be better, but overall I think 10,000 wins. I’ve setup different macros to switch depending on content so it’s easy if I need to.

For extreme high nit sources like The Meg chapter 8, if I set Custom HDR/AVI Tab’s Max Luminance to 10,000 nits and the DV Data Block’s max luminance to 1,000 nits (or use Custom EDID 9 or 10 on Vertex2) then it dynamically tone maps to where there are absolutely no blown out highlights or crushed and dark blacks or low level. The details you see are astonishing. Low APL movies like Blade Runner 2049 and Arrival and The Mandalorian have awesome low level details and brightness, which many complain are too dark.

See my reply above about using 10,000 nits. The lower you go, the flatter and less “HDR-Like” the image gets. I noticed once you get down to about 600-800 nits and below the image is way too flat and lifeless. 1,000 is about as low as I’ll go.

Test it with 10,000 nits and tell me what you get and see. I’d love to know what your Atomos shows. I was thinking of getting one myself! A lot of it could have to do with what the display’s characteristics add to it though. My experiences are with a BenQ LK990 and Samsung LSP9T so far. Others like the JVCs act a little differently from what I read.

Oh which EDID mode are you using with the HDFury by the way?

If you’re using a Custom EDID 0-99 (red in picture) then it isn’t using the connected display’s EDID at all.

You have to use Automix (green in picture) and add in things you want to add to the display’s native capabilities, like the Custom DV Datablock, HDR10+, etc.

Exactly what I use, did that as well in the past.

Yes I always applied the dv meta lum values,
Bt2020 10k comes out unwatchable bright scenes are over blown.
What are watching it on?
Their is nothing to watch 10k on besides the monitor it self which does look beautiful @10k nits
Bc the capture file also becomes 10knits as well
But that does not match the 1000nit hdr version
Also tv led can’t use 10k nits, well fully I’m sure it will utilize the uhdtv max lum values
Forcing 10knit don’t look rite on the CX or any UhD tv out there.
