Dolby Vision now possible through MP4 Mux.

[deadchip12]

I converted the mkv remux version of Raya and the Last Dragon (2021), which only supports hdr10, to bdmv folder and when I play it on the x700 and Dolby Vision left ON, it's not converted to Dolby Vision; instead, the colors are muted, like when you play an hdr film on a sdr display without any conversion. Turning off Dolby Vision and the film will play in HDR correctly.

strange ...
are you sure the mkv you remuxed wasn't profile 8 hybrid? I think P8 muxed in BDMV plays in SDR on the x700.

I edited my comment above after I did some more tests.

I tested two hdr10 films: Black Widow (original bluray structure converted to bdmv folder using tsmuxer) & Raya and the Last Dragon (mkv remux converted to bdmv folder using tsmuxer). When I play them on the x700 with Dolby Vision left ON, both are not converted to Dolby Vision; instead, the colors on them appear muted, like when you play an hdr film on an sdr display without any conversion. Turning off Dolby Vision and those films will play in HDR correctly.

How do I check the profile of the file I have?

Some more observations:
-For hdr movies, subtitles appear too bright. This is not the case with dolby vision movies.
-When I play mp4 dolby vision file (the book of boba fett season 1 episode 1), it stutters at certain points. Converting the file to ts seems to fix it. And the subtitle works. But it's too bright, despite being in dolby vision.
-We can't fast forward or rewind to an exact point of a movie (like what we can do on pc)?

Thaks. I will check the dv profile of those films later and report back.

Regarding your spreadsheet, does the bdmv trick works for all dv profiles or just dual track dual layer?

yes BDMV is for dual-track dual-layer files

BDMV is ideal for FEL DV movies. For all the MEL bluray or Hybrid DV releases, profile 8 TS is the best you can get on the x700 (bug-free).

Most, if not all, of the profile 7 Dolby Vision films that I see show Video #1 and Video #2. Does this mean they are dual track? Is there any particular film that is profile 7 single track?

It's not really correct place to ask, but I figure the best, since many of you did analyze various aspect of streaming services content.

Is lossy dolby atmos from streaming mixed the same way as lossless dolby atmos from disk?

In other words, which one is better:

Dolby vision FEL + Dolby Atmos DD+ from streaming
Dolby vision FEL + 5.1 DD+ 1536kb/s from Dolby Atmos 7.1 disk track

DV profile 7 is intended for UHDBD. It holds a base-layer and enhancement layer, which are muxed as separate videotracks in a m2ts container. So indeed that is called "dual track dual layer". I've never seen a Dolby Vision UHDBD that has one videotrack. MP4 can also be muxed as dual track dual layer.

Software like MakeMKV interleaves the two layers into one videotrack. The result still is a DV profile 7 mkv, but obviously now it's called "single track dual layer".

Does anyone know a way to reduce the brightness of subtitles in hdr? They are blinding in dark scenes.

Thanks to quietvoid you can use this great tool: https://github.com/quietvoid/subtitle_tonemap

- put "BDSup2Sub512.jar" inside the folder with "subtitle_tonemap.exe"

- example of usage: subtitle_tonemap.exe "folder_with_pgs_subs" -o "folder_with_tonemapped_subs" -p 62

- the path to folders with .pgs subs should end without "\"

sorry but I downloaded the zip file but there's no subtitle_tonemap.exe. Could you let me know where it is?

Also, how do we extract the pgs sub and reattach the tonemapped version to the film afterwards?

You need to tonemap your pgs subs before you mux them.

Thanks for the exe file. How do I extract the original pgs sub file from the film's bluray folder and reattach the tonemapped version to the film?

Hi.

This thread has become massive, and I am not sure if this is the right place to ask, since it is probably not makemkv related, but DV related.

I got a mkv file showing the following in mediainfo:

Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible

How it has been made I have no idea, and I don't know if the EL is MEL or FEL. All I know is that the BL has been encoded. If this has been done with the EL still inside the source file, or if they have been demuxed and just the BL encoded and the EL injected afterwards I don't know.

The mkv file itself is cropped to 3840x1636 with no black areas top/bottom.

When I do a frameinfo (from DVT tools) of frame 1000 I see the following:

"Level5": {
"active_area_left_offset": 0,
"active_area_right_offset": 0,
"active_area_top_offset": 263,
"active_area_bottom_offset": 263
}

Is it really correct that top/bottom should be set to 263, when the BL has been encoded and been cropped. Does it not mean that the DV in the EL will only have an active area of 3577x1899, and the top/bottom 263 pixels will have no DV? Should top and bottom not be set to zero, when the BL has been cropped.

This might very well be a stupid question, but I am just trying to get my head around all this DV stuff

Thanks in advance.

Demux them using eac3to or DGDemux for example -> put them in some folder named "subs" -> create another folder inside folder "subs" named "tonemapped" -> open subtitle_tonemap.exe in cmd.exe and use this command: subtitle_tonemap.exe "C:\bin\subs" -o "C:\bin\subs\tonemapped" -p 60
-o = output
-p = % to multiply the final color of the subtitle. Defaults to 60%

-> mux them with MKVToolnix to your video file... that's it, done.

Is it really correct that top/bottom should be set to 263, when the BL has been encoded and been cropped.

nop, that's incorrect and if you play the file on an LG OLED, it will display the movie overcropped in 3840x1110...
Profile 7 BL, shouldn't be re-encoded. I read somewhere here that the BL contains EL residues(which are lost when you re-encode).

EDIT: because the EL is not cropped, L5 of 263/263 should not overcrop...
