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 find the folder that contains pgs subs?
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.

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...

My films are in bluray folder structure, so I used tsmuxer to demux the subtitle file. I followed the instructions but got this error:

actually my films are in bluray folder structure, so does this method still work?
Are those udh blu-rays in folder structure? Those should already have tonemapped subs so watching them in HDR should not be a problem . Only subtitles from regular blu-rays ought to be tonemapped when putting them to HDR video.
You can still create a folder structure using TSmuxer if I am not mistaken.

Thank you very much for the answer.

What if the BL and the EL is demuxed, the BL encoded (cropped) and then after encoding, either inject the static RPU data, with top/bottom set to 0, or join the encoded BL with the non encoded EL (FEL/MEL) and then mux with mkvmerge afterwards?

Or is it just a doomedays project to make a encoded and cropped Single Track / Dual Layer mkv file with DV data that actually works (there are plenty of them to be found, but how they are made I don't know).

Looking in mediainfo all looks fine and dandy. But the question should be wether the files actually works or not.

All this DV stuff makes my head spin :-)

Yes they are uhd blurays. Some movies still have overly bright subtitles in hdr - Disney movies like Black Widow or Spider-Man: Far From Home. You don't see any uhd movies with such issue on your end? This seems to be quite a common complaints, especially among people who watch movies in the dark.

Edit: wait, maybe I demuxed the wrong sub. Let me try again.

L5 should be set to 0 when the video is cropped. And profile 8 should be used.
The BL of a FEL bluray should not be re-encoded at all( even if the file works). see viewtopic.php?p=94396#p94396

Maybe there is a issue with those subs demuxed using tsmuxer... Try with eac3to: http://madshi.net/eac3to.zip

in cmd: eac3to.exe "blu-ray_folder" [choose 1) or 2) or different choice if blu-rays got more playlists] and then number for subtitles you want with the path where you want it

example: eac3to.exe "black_widow_uhd" 1) 6:C:\bin\english.sup 7:C:\bin\spanish.sup etc.

EDIT: CAN YOU UPLOAD THAT .sup file somewhere for me? you can PM me if you want.

if it's mel dual layer on the disc you can encode base layer and convert mel p7 extension layer to p8 rpu and inject that into encoded bl

fel has to remain untouched (unless access to pro tools?) from what i've seen

this is what I do with my UHD files

something to note found over on Plex forums someone here might find useful

apple tv users can only stream p5 to apple tv if codec id is dvh1, not with dvhe as mp4muxer puts out
