anyway the problem is the EL and german discs
I wonder if all the French UHD-BD should be verified now. It looks like Blade 1998 FEL FRA BD has the same issue :(

So, to be clear, is this a disc mastering issue? A MakeMKV issue? Or a combination?

Sorry to be late on this. What's the best way to verify our backups? Thanks!

It's a disc authoring/encoding issue.
To verify your makemkv rip, just extract the RPU, info/plot it with dovi_tool, and check if the framecount matches the video.

Is there a setting somewhere i can change to save the log file of the entire process when i run 8-2-1.
i would like to save it to a txt file if possible in the same folder.

I could but it makes the x265.exe progress bar to display a new line for each few frames. I don't know how to keep the progress bar on the same line and export the log at the same time.

If you still want it, you can modify line 17370

Code: Select all

"%x265_path%" %settings% %static_metadata% %P8RPU% --input "%TEMP%script.avs" --output "%output_path%%filename%%encodetype%.hevc" & echo off & set HDR="%output_path%%filename%%encodetype%.hevc"& goto :MUXER
change it to:

Code: Select all

"%x265_path%" %settings% %static_metadata% %P8RPU% --input "%TEMP%script.avs" --output "%output_path%%filename%%encodetype%.hevc" 2>&1 | PowerShell -Command "$input | Tee-Object -FilePath \"%output_path%%filename%_encode_log.txt\""
@echo off
set HDR="%output_path%%filename%%encodetype%.hevc"& goto :MUXER


EDIT:
added an option to export x265 encoding logs at line 167 (off by default)

hello everybody
can someone explain step by step how to make mkv remux from these bluray with bad authoring ?
thank you very much

EDIT : I think i've found, just import m2ts file in dovi_scripts, so simple as that ?

@RESET_9999 can the RPU coming from the korean UHD Blu-ray be injected in the french UHD Blu-ray in your opinion?

Plots: https://slow.pics/c/fDGDHo8Y

PQ: https://slow.pics/c/TiKmEYmY

I'm not 100% sure because there's a slight PQ difference between the two. For example in comparison number 12 you can clearly see it in the color of the red pencil.

You can also see in the hand, envelope and bags in this frame, so brightness seems to be slightly different, so I doubt it: https://slow.pics/c/kecXpEAV

Also, there was barely any actual L2 trim in the KOR UHD BD RPU, so generating a new one for FRA UHD BD makes even more sense. Cheers. :)

red looks indeed slightly different but according to your HDR plot, it looks close enough IMO. The 100nits trim doesnt add much and the 1000nits trim is blank meaning there won't be an artistic trim effect for any display with a target equal or higher to 1000nits so it might be better to just generate a new CMV4.0 RPU.

PS: You should uncheck ''Optimize images'' when you do an HDR comparison because this option removes the HDR10 trigger metadata and the images can no longer be viewed natively in HDR.

You have to extract the RPU from the original m2ts. You might have to remux the HDR10 BL first before running workflow 1 because im not sure of what will happen if you input a DT-DL m2ts and a P7 RPU

i think it's ok, i just made workflow 1-7 with the m2ts file and the number of frame of the rpu is correct. it was incorrect with the mkv from makemkv.
And these blu-ray are MEL so P8 is enough :)

bluray done : soul eater, mississippi burning and late night with the devil

"Strange Darling" from Capelight is another faulty authored disc, which MakeMKV exposes. Its MEL, so no problem with profile 8.1. after DGDemux.

Thanks. is it also oversaturated like the HDR10 BD ?
