Dolby Vision now possible through MP4 Mux.

[BringerChaos]

I don't suppose anyone happens to know which profile(s) work on Sony Bravia KD-65X9500G via plex OR Firestick 4K plex?
Also if its capable of playing both BL+EL+RPU or BL+RPU?
TV doesn't have a dolby vision icon haha.

[mike admin]

Out of curiousity did anyone try reencoding the BL ( same res just lower bitrate x265 ) and then mux it with the original EL into mp4? I wonder if that would be still playble on my LG C7 internal player.

Non-MEL EL contains residue - i.e. result=some_RPU_magic_function(BL+EL) . By changing BL (and re-encoding is a destructive process) you are bound to get an incorrect result.

Have you had a chance to look at that LG profile 4 BL+EL+RPU video to see if you notice any oddities when compared to another soc?

Nop, I cannot get a match with that LG profile 4 BL+EL+RPU video or any video that has an EL.
Shield Plex RGB vertex VS LG C8 internal app

So I thought maybe the problem was caused by the DV files that are HDR10 and DV compatible(limited range). So I compared the Glass Blowing BL+ RPU demos. One is HDR10 and DV compatible(limited range) and the other video is full range profile 5 DV only.
looks pretty much the same to me.. I still see a slight difference compared to the C8(but not in real life) but nothing major like any BL+EL+RPU.

*notes: the glass blowing samples don't work in my x700 so that's why I used the c8 for the comparisons. Downside: almost impossible to pause at the same frame.

Ah that's disappointing. I went ahead and demuxed that demo file with yusecope's demuxer and it does look like it's FEL (~200MB BL:~50MB EL), so that could explain why it's not playing it correctly.

[RESET_9999]

I wonder if a dvhe.08.09, BL+RPU, HDR10 compatible / SMPTE ST 2086, HDR10 compatible UHD-BD rip would output proper colors. Can we create such a file with the tools we have?

I know the EL is gone but if it is color accurate, that could be a good workaround until Nvidia finds what the problem is.

Yep with yusecope's tool in mode 2 to strip out the EL and an unaltered nightly version of tsmuxer will give you a profile 8 video. I can try that with the doctor sleep scene actually. I'll post the clip shortly for you to try as well.

[shawnc22]

Here you go:

From first glance, there doesn't seem to be much of a difference between this and the profile 4 BL+EL+RPU video. But maybe there will be with the vertex workaround?

[RESET_9999]

thank's .. unfortunately, red artifacts still present.

[MastaG]

As I haven't been following much lately..
But I remember that the LG C8 internal player had some performance problems when remuxing some FEL Blu-ray movies.
Examples are 1917 and Gemini Man.
It doesn't really matter whether I used txmuxer or mp4muxer (profile 04 or 06) or even dual pid (profile 07).

The only way to get those movies to play smoothly was by discarding the EL layer by merging the two layers using yusesope's tool in mode 2 (BL+RPU).

Now some people claimed they got these movies to play smooth by merging both layers using yusesope's tool in mode 1 (BL+EL+RPU) and then using an old or modified version of txmuxer which would flag the movie as profile 08.

But that is like telling your TV there's no full EL right? As profile 08 and 05 are basically indicating BL+RPU.
So perhaps the reason for these FEL movies playing smooth when setting profile 08 is because the internal player doesn't process the EL at all?

Which version of TSMuxer I should be using to create a profile 7 TS or M2TS containers with my Sony X700? Is profile 7 best way to play DV UHD disk videos with X700?

[McZuzlak]

Is it planned for feature makemkv revisions to create specific dv profiles without third party apps ?

The new Zidoo will support dv but profile 7 is excluded. Its confirmed that they are working on the SDK, and developing Dolby Vision support for MKV containers regarding profiles 4,5,8 & 9.

[flashback8]

I doubt MakeMKV will support conversion to other DV profiles. The policy has always been to just copy the data over into a new container, not to translate the data into other forms beyond what's absolutely necessary to get the data into MKV form. A more likely approach, IMO, would be for players to support on-the-fly conversion into other profiles. I suppose MakeMKV could potentially write a program that allows for conversion of MKVs to other profiles. I wouldn't count on it but you never know.

Of course, I could be wrong about all of this. :)

anyone?

[mulucy]

Hy guys, anybody know what's the best way to embed sub/idx or ass subtitles into the DV mp4? I play my DV files via X700 and for some reason it can't read ass subs properly and sub/idx at all, if I put them in the same folder as DV mp4. Thanks!

You don't have to use the MP4 container anymore with the x700. You can remux your UHD bluray disc directly to .TS or .M2TS using this tsMuxer:

https://drive.google.com/file/d/1IWYPO4 ... sp=sharing

DV, Atmos and subs will work.

it appears the file has been removed. Do you still have a copy of Tsmuxer for the Profile 7? Thank you in advance!
