Dolby Vision now possible through MP4 Mux.

[RESET_9999]

After reading here and there im getting confusing with the dv profiles the mp4muxer and the m2ts/ts files.

I have a Lg C1 and a Sony x700

1. i used to rip a dv movie and just make the mp4 dual layer way putting profile 7 always. That changes for a mel or fel movies?.

2. knowing now i was wrong and i could use a m2ts instead of a mp4 file for a dual layer playback, do i lose something if i change that profile 7 dv mp4 with mkvtoolnix and then tsmuxer?

3. p7 > p8 > p5 ?

4. isnt the dv backup dual layer the best a movie can be seen?

5. is better a dovip8 movie than a p7 mp4 muxed movie with their native dual layers from the disk?

Im feeling like a retard with these 4 years old questions but if anybody can explain me this would be very nice.

As glc650 said, the best DV is FEL P7 (dual-layer) but not all the movies are FEL. Note that your TV internal app won't play FEL movies properly because it lack of a 2nd decoder but your x700 will play properly pretty much anything you throw at him

P7 fel(always dual layer) = 1 HDR10 base layer 10bits + 12bits data in EL(2 extra bits) + dynamic metadata in RPU
P7 mel (always dual layer) = 1 HDR10 base layer 10bits + blank EL (no extra bit) + dynamic metadata in RPU
P8 (always mel and single layer) = 1 HDR10 base layer 10bits + dynamic metadata in RPU
P5 (always single layer) = none-tonemapped DV base layer(green and purple colors) + dynamic metadata in RPU
P4 (dual layer,FEL or MEL) = 1 SDR base layer + FEL or MEL + dynamic metadata in RPU

so it goes like this:
P7 fel > P7 mel = P8 = P5

*Profile 7 can be merged in a single track (makemkv) but it's still dual layer DV.
*Profile 8 can also have an HLG base layer (iphone recording) so this format is compatible with HLG, SDR and DV.
*profile 5 DV : I'm not sure if it's 12bits or 10 bits because there's this description about my profile 5 patterns: ''10bits encoded remapped 12bits''. Not really sure what it means but it sounds like profile 5 could be 12bits as well.

- Dolby Laboratories
Since current Dolby Vision test patterns are limited, we decided to create an entire suite utilizing profile 5, the most commonly used profile amongst manufacturers. Profile 5, typically utilized for streaming Dolby Vision content, encompasses Dolby Vision’s proprietary IPT for color primaries and color matrix, along with the use of full range for RGB. This test pattern suite incorporates an UltraHD 3840x2160 resolution, proprietary IPT similar to BT.2100 ICtCp, 10-Bit encoded/12-bit remapped and a ST.2084 transfer function. This project follows the same idea behind our “UltraHD|HDR-10 Test Pattern Suite”, an attainable solution to calibrate and/or measure your new HDR display, without having to spend thousands on a new UHD/HDR test pattern generator.

Amazing, even my 4 years old brain (im 40 lol) can understand now, so my mp4 mel dual layer movies are the same as the p8 movies so i guess i only care about p8 movies if theres no uhd dv version of that movie, if not just stick with my original rip.

You can convert dual-layer profile 7 mel uhd bluray to single layer profile 8. You don't lose any quality and there's a benefit in doing that when you use a sony x700 bluray player.
P8 is actually the profile I use for all the MEL DV bluray because the x700 doesnt have the green screen bug with profile 8.

so here's how I watch DV movies on the x700

FEL P7 : remuxed to AVCHD bluray folder structure
MEL P7: converted to single layer profile 8 TS

*ts p8 playback will still have seeking issues with long movies and no automatic forced subtitles though.

[staknhalo]

I keep a DL P7 mp4 and a SL P8 mp4 inline together in Plex just so that I have DV7, HDR10 and/or DV8 all already available depending on the local device's playback capability

Sucks having to keep 2 versions of each movie space wise (why I encode my digital copies' base HDR10 layer to 45mbps - I find this quality still alright over streaming 4K and I have the physical disc still for first watching and 1:1 hard copy backup if I ever need it), but it makes it the easiest for broad playback support

Hi all,

i have a problem with one specific DV video the x700 won't play.
Its a SAW (2004) remux, taken the video from the US UHD and the german DTS HD MA blu-ray audio source.

As always using ts-muxer converting mkv to ts.
This time with activated DV the x700 doesn't play the movie. With DV off the movie played fine in HDR10.

I have no problem playing DV for this types of "selfmade remux" before, for example Donnie Darko has no issues at all.
So whats the problem with SAW and is there anything i can do, onvert DV Profil, FEL to MEL, single track to dual track?

Thanks.

You can now generate RPU metadata in v0.4.0, see documentation: https://github.com/quietvoid/dovi_tool/ ... nerator.md

You can find it here: https://github.com/quietvoid/dovi_tool/ ... /tag/0.4.0

I wonder is it possible (in theory) to generate a dynamic RPU based on data from MadVR MadmeasureHDR Optimizer tool?

Of course it's possible, but there would be no creative intent adjustments.

[Manixx2020beyound]

What about content that is graded for dv
& includes the (DV-meta-XML adjustments) but of course does not have an Rpu is that possible?
Eg.Dv master file with xml.
For those who don’t have the dv encoding tools to build an Rpu tru sdi.

[quietvoid]

Well yes, the RPU is usually generated from the XML.
I just don't personally have a usecase for it, talked about it here: https://forum.doom9.org/showthread.php? ... ost1949650

[RESET_9999]

i have a problem with one specific DV video the x700 won't play.

yep, some single-track dual-layer movies won't play on the x700. This is why it's better to use the dual-track dual-layer format because every single movie will work. Nothing i hate more than getting ready to watch a movie just to realize it doesnt play...

So you have two options:

1, demux with yusesope tool and rebuild a new DT-DL TS.
or
2, Get the original disc and remux a new DT-DL TS.

That would help the grading community,
For those guys like myself 4k,6k,8k cameras
And do their own grading without doblyvision license fees
No secondary trim pass doe.
To my knowledge the doblyvision fees are only for secondary trim passes/Rpu creation & final encode of the doblyvision master to hevc

Ok, not sure when I'll get around to it.

[deadchip12]

Never seen anything like what you're describing.

Very hard to describe what I see. It can't be captured on camera either. Need to watch the oled in a pitch dark room and then you will see such pattern. I have owned the c7, c8, and c9; all have this issue. It drives me nuts. I remember one guy on avsforum posted about the same thing a while ago but most people didn't notice it on their sets so they ignored his post.

i think i know what are you seeing...lol

i had that issue in my lg b6 when used a blueish color temperature and full motion like 10/10, then in some black scenes appears a white worm for some places lol, fixed with a standard warm50(2) and no motion, overall a standard recommended configuration, the lines started to appear when tried cold color or vivid configurations plus motion 10/10 and 10/10

I always keep temp color at warm 2 and motion off

Amazing, even my 4 years old brain (im 40 lol) can understand now, so my mp4 mel dual layer movies are the same as the p8 movies so i guess i only care about p8 movies if theres no uhd dv version of that movie, if not just stick with my original rip.

You can convert dual-layer profile 7 mel uhd bluray to single layer profile 8. You don't lose any quality and there's a benefit in doing that when you use a sony x700 bluray player.
P8 is actually the profile I use for all the MEL DV bluray because the x700 doesnt have the green screen bug with profile 8.

so here's how I watch DV movies on the x700

FEL P7 : remuxed to AVCHD bluray folder structure
MEL P7: converted to single layer profile 8 TS

*ts p8 playback will still have seeking issues with long movies and no automatic forced subtitles though.

Why dont you remux mel p7 to bluray folder structure also? That will avoid all the bugs, no?

[RESET_9999]

Why dont you remux mel p7 to bluray folder structure also? That will avoid all the bugs, no?

Because the seeking issue with long movies is very rare so it bothers me less than having to make a bluray folder and keep only one at the root of the HDD.
Of course for long movies (MEL) like LOTR/hobbits, I still use bluray folders for playback but for 95% of the mel movies, P8 TS works just fine without any issue. Plus I prefer to store my movies in my NAS in TS or MKV containers.
Forced subs is not a problem at all for me since I can easily find any subtitle track in SRT when I make my DV TS file.

I wish the shield didn't have color issues though(or that the ugoos was stable) because that is what I would use for mel DV. Dune and Zidoo player looks interesting but very expensive since I would only use for mel.

Awesome. Option 1 using this guide worked like a charm.
