Dolby Vision now possible through MP4 Mux.

[KingLir]

I am not sure I got all the information here correctly....

After I rip, using latest MakeMKV 1.15.3, UHD disc with Dolby Vision (Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible)
Is there a way to convert it (MP4 or MKV) to DV profile 5 for playback on Apple TV 4K ? That of the DV stream and NOT the HDR10 fallback.
If it is possiable, technically, what is the data lost when converting from profile 7 to 5 ?

Ok but for testing/debugging reason on the oppo 203, i want to have a single track layer in a ts file, not double track.

Users have reported that single Layer DV in ts files are working on the oppo

Edit ; By working i mean that dolby vision is working / detected by the TV

I think for testing you should go the other way around, if it works with mkvtoolnix:
find mp4/ts files here couple of pages back that Oppo plays back and then convert it to mkv.
Let me know if you won't find any of these, I'll dig it up for you.
Also you can ask other guys here with a Shield to test those mkvs if you don't have a Shiled (I don't).

Has anyone here been able to create a Single Track Dual Layer MEL MKV for 1917 which works on plex as expected?

I have tried creating:
MEL with HDR10Plus using GAMMA
MEL without HDR10Plus using GAMMA
MEL with HDR10Plus using BETA
MEL without HDR10Plus using BETA

All these files play correctly but Plex cannot seek forward in any of them / resume playback from a point in the middle of the movie and I can only start the file from beginning.

If anyone has been able to create a MEL file for 1917 that works properly on Plex please let me know how!

Yesterday I merged the 2 videos (using mkvtoolnix) of The Lord of the Rings: The Fellowship of the Ring, and with mp4muxer (dual layer) for DoVi. I've played it on my LG TV via external HDD and the video stutters (laggy)

Slightly off topic, but say I want to convert dual layer files to single layer ones that will play on plex as a .ts, is the simplest way to use makemkv then use tsmuxer on the resulting mkv to make a ts?

Ideally I want a ts so I can play files on both plex (for convenience) and my X700 (for quality, assuming this process doesn't decrease that). I also want to maintain Atmos.

Edit: I may mean Dual track dual layer to single track, getting tired and confused after catching up on this thread!

Pretty much, but @RESET9999 may have the definitive answer on this, but I don't believe the x700 can play single track dual layer files.

[baker99]

Thanks shawnc22, I had thought the X700 playback could be an issue, guess I'll keep two versions of each file for now (I'm going to need to buy more hard drives!),

[RESET_9999]

The x700 supports most of the single-track / double-layer files. All the MEL movies work but some FEL movies don't work. Also the ST-DL files don't have the reboot bug.
I didn't find a dual-track / dual-layer file that doesn't work yet.

What do you guys do for multi disc dv movies on plex (lawrence of arabia, Lotr trilogy) ? When I use the naming format suggested by plex where you put bot both parts in the same folder and name them "part 1" and "part 2" it does combine both files but I lose the dv layer

[SamuriHL]

Merge them with mkvtoolnix.

[4knewbie]

I use dual layer dv mp4, I don’t think I can merge the files

[SamuriHL]

Probably not. I don't know that plex is going to notice though. Your part 1 and 2 I mean.

This is odd.. Does the Dolby Vision logo matter? I am able to play my SL DV(7.06) mkvs through the plex app on the shield pro (2019). The DV logo shows.. it plays fine except I noticed color issues playing Lord of the rings - Two Towers, Joker and Gemini man. My plex server is on my WIN 10 PC. My LG CX also has a plex app. While these mkvs don't play through the USB on the CX, they do play via my server to the plex app on the CX. Although the HDR logo shows on the CX plex app while playing these mkvs, they seem to be actually playing in DV. The colors are correct and the detail is definitely different than the HDR versions. In a blind test without the logos, how could you tell the difference.. your eyes. It could be that whatever is supposed to trigger the DV flag in these mkvs confuses the CX plex app and it shows the HDR logo instead of the DV logo(a possibility). Just because the flag does not show as DV, does that mean it is not DV? We know Mike and Yuescope's tools work, and it could be a coding thing that's causing this mishap on the CX. Do we really need the logo to verify DV? I've re-watched the Joker and Gemini Man SL DV's and they look 100% better this way vs the shield plex app wit screwy colors. Can someone with a CX try this method versus the shield 2019 and see if they agree or disagree?

Well if there's no logo, then the TV is not in DV mode; there's really no way around it. The WebOS plex app has no support for DV in MKVs so its defaulting to the HDR10 layer on playback. I would go back and double check the picture mode you're in during HDR & DV playback from the Shield and the same for playback from TV apps. I have it set to Cinema for everything and HDR looks the same to me on both the Shield and TV apps.

Hi, you might be right, I think Cinema Home (User) is subjectively brighter on the LG for internal apps, if you choose Cinema (User) for apps and HDMI you will get the same curve.
