Not sure. ffmpeg isn't keeping the Dolby Vision config when converting to mov. Only mp4.NiCE77 wrote: ↑Tue May 24, 2022 6:21 am@quietvoid:
I also created mp4 and ts versions of your test files: https://1drv.ms/u/s!Ahh4FiB9hIuT-ETf93f ... D?e=nOgBuQ
Is it possible that the Apple TV could only read the RPU from the mov container? How can I make a mov file?

Re: Dolby Vision now possible through MP4 Mux.
nop, you cannot improve the conversion. it's the best you can get with the input source you have.rophel wrote: ↑Tue May 24, 2022 5:26 amUsing Reset_9999's scripts and had some questions:
How accurate is the conversion of HDR10plus to DV? Anything I can do to improve the conversion? I don't have an HDR10+ display to compare.
Also, sometimes I end up with both an .hevc and a .bin file when using the script, etc. Do I need to do anything with the .bin or just mux the .hevc into a mkv? I'm not losing anything by discarding the .bin, correct? S
you can delete the .bin file.
I keep a copy because I want to share the rpu with my friends.
Sorry for my English.

Re: Dolby Vision now possible through MP4 Mux.
For movies with neither a Dolby Vision track nor HDR10+ metadata to convert, how much of a difference am I likely to notice on an LG C1 between auto-generating shot-by-shot metadata versus just playing it back with static metadata? Is it more likely to make a difference in a brighter room (so Dolby Vision IQ can do its thing) than a fully dark room?
Finally, is there any way to generate shot-by-shot metadata on Linux, or do I have to use the madMeasureHDR.exe program under Windows?
Thanks.

Re: Dolby Vision now possible through MP4 Mux.
I just made a profile 5 doblyvision encode (now-possible) encoded on a pc
This test was made from a hdr10 base layer.
And it works on apple tv
I’ll wait for reset9999 to compare

Re: Dolby Vision now possible through MP4 Mux.
HDR10 with madvr-generated DV is certainly better than just static HDR10. You will notice a difference, especially with bright content.rkjnsn wrote: ↑Tue May 24, 2022 11:44 pmFor movies with neither a Dolby Vision track nor HDR10+ metadata to convert, how much of a difference am I likely to notice on an LG C1 between auto-generating shot-by-shot metadata versus just playing it back with static metadata?

Re: Dolby Vision now possible through MP4 Mux.
@RESET_9999 Thanks for the quick reply!
Another issue (and I've spent time searching the forum via Google so sorry if this has been covered):
When I do WEB-DL only hybrids i.e. both DV and HDR are from WEB-DLs, with most films I get audio that is wildly out of sync. TV shows have no issues, strangely. Source files are MKVs, I use the hybrid maker script, then mux the resulting hevc file with the HDR file's audio and subs using mkvtoolnix gui.
I saw some mention of trying better release groups, but has anyone had any success in resolving this? I am using two files from the same release group and confirm exact same length via jumping to specific frames, etc.
I tried some various things, using TSMuxer to turn the end MKV into a TS seemed to get the audio only a second or so off...while the MKV was WILDLY off. So odd.

Re: Dolby Vision now possible through MP4 Mux.
Here is a p5 sample for u guys to test
This was encoded using doblyvision encoding engine & h265, RPU is a true P5 even l4 included
Source file spares & munsil m2ts untouched Mel.
Test on Apple TV’s

Also for a couple of secs woksr on plex app before a message appears on the screen, plex complaining the network speed is too low (it is wired gigabit).

Re: Dolby Vision now possible through MP4 Mux.
Except that it is not a true P7/P8 to P5 conversion. It is newly generated metadata and all the artistic trims are gone. Basically the same as generating DV from madvr.
In order to get the same DV, the dovi_tool would need to be able to convert RPU to XML (same structure as resolve XML). Then we could import the metadata in resolve and encode it to P5.
Will be useful to convert all my HDR10 patterns to Profile 5 though.

It would heavily depend on a file.rkjnsn wrote: ↑Tue May 24, 2022 11:44 pmFor movies with neither a Dolby Vision track nor HDR10+ metadata to convert, how much of a difference am I likely to notice on an LG C1 between auto-generating shot-by-shot metadata versus just playing it back with static metadata?

Not everybody fills full static metadata, some are using incorrect metadata that ruins tone mapping for OLED tvs without good DTM (LG)
For example, iTunes, ATV and Disney content (including disks) contains MaxCLL value way above what you can actually see in the actual movie. And if it goes above your TV's maximum brightness it will skew the EOTF target and increase brightness roll off. So 500 nits image will be presented in 350 nits. Warner brothers does the same stupid shit, when their logo is about 900 nits bright and the entire movie is 150-200 nits MaxFALL.
Famously, new Spider-Man has MaxCLL of 10000 nits even though it was graded on Sony OLED with maximum brightness of 1000 nits. It also scales up MaxFALL value so it messess up all the tone mapping in the film. Thankfully most of those fucked up movies come with Dolby Vision.
Now in this particular example, if the movie is only available in HDR10 (like Batman v Superman) MadVR DV would help alot as it will allow your TV work to its best potential and it will exclude that one 10000 nits frame from everything else in the content.

Re: Dolby Vision now possible through MP4 Mux.
Also a p5 encoded from a master MxF that already has been made with Dolbyvision meta retains all the artistic intent in the conversion to p5 tested that as well.RESET_9999 wrote: ↑Wed May 25, 2022 2:29 pmExcept that it is not a true P7/P8 to P5 conversion.

Yep Rpu to xml would put the icing on the cake..

Re: Dolby Vision now possible through MP4 Mux.
So @manix converted the "mutli pattern" to profile 5 and as expected, no more colorspace conversion/clipping issues on the Shield. No blue banding as well.
We discovered something else, something quite big. The DV 8.1 MP4 encoded directly from Resolve doesn't have the famous color issue bug on the Shield!!!! what the hell!!!
So it means there is something in quietvoid/yusesope/makemkv DV remuxing that the Shield doesnt like at all... Strange though that only the Shield seem to be affected.
no color issues:
P5 pattern : https://drive.google.com/file/d/1gFrasF ... sp=sharing
P8.1 pattern (DV MP4 straight from resolve) : https://drive.google.com/file/d/1fCjcMH ... sp=sharing
color issues:
P8.1 pattern (dovi_tool XML from resolve) :https://drive.google.com/file/d/1Aq3v03 ... sp=sharing
P8.1 pattern (dovi_tool madvr) : https://drive.google.com/file/d/1NbXM2p ... sp=sharing
We are going to make a P8.1 of Doctor Sleep in resolve, I bet there's no more red push...

Re: Dolby Vision now possible through MP4 Mux.
This has to be one of the biggest news in this thread in a while. Hopefully the difference can be reverse engineered (looks hopeful at @quietvoid). I really thought we’d need to wait for a complete new SoC to maybe one day get DV (at least MEL)+Passthrough Audio in a device to simply stream like the Shield.
