Yes you can remove the DV metadata/layer with 6-1-2 but you will have to mux the new HEVC file to MKV yourself with mkvtoolnix.valington wrote: Thu May 11, 2023 11:24 am Hi , is it possible to mux with your script MKV 7 PROFILE DOLVY VISION to
MKV HDR10+ and remove dolby vision metadate, cause i m asking it for qd-oled samsung
So with Tool its possible to remove DV metadata , is there a way to convert that DV metadata to HDR10+ metadata ?RESET_9999 wrote: Thu May 11, 2023 12:09 pm Yes you can remove the DV metadata/layer with 6-1-2 but you will have to mux the new HEVC file to MKV yourself with mkvtoolnix.
You use the original profile 7 RPU for DoViBaker.NiCE77 wrote: Fri May 12, 2023 6:24 am @RESET_9999
Can you give me some guidance on DoViBaker?
Let's assume this is the starting script:
bl=DGSource("blclip.dgi")
el=DGSource("elclip.dgi")
DoViBaker(bl,el,rpu="RPU.bin")
If I recompress this with e.g. Handbrake, I get a 10 bit HEVC HDR10 stream containing the FEL data, to which I can add the RPU converted to Profile 8 with dovi_tool.
So why does DoViBaker need the RPU?
In this case, in which mode should the RPU be converted to P8 (preserving mapping or not)?
Thanks, but I found this comment: https://github.com/erazortt/DoViBaker/i ... 1259843741quietvoid wrote: Fri May 12, 2023 10:34 amYou use the original profile 7 RPU for DoViBaker.NiCE77 wrote: Fri May 12, 2023 6:24 am @RESET_9999

And for the encode you convert to profile 8.1 (mode 2).
You have to be careful with DoViBaker as it outputs RGB by default, and a later conversion could make the colours wrong when encoding.
Reinjecting the *original* RPU is wrong. When converted to profile 8.1 it is fine.NiCE77 wrote: Fri May 12, 2023 10:55 amThanks, but I found this comment: https://github.com/erazortt/DoViBaker/i ... 1259843741
So the result will not be good if we inject the RPU because double processing. But then I don't really understand what this tool is for?

As long as you don't tonemap using the trims in DoViBaker.
DoViBaker uses the mapping metadata and NLQ metadata to reconstruct the FEL image.
All this metadata is removed by profile 8.1 conversion (for FEL).
What would be a good FFMPEG command line to create the new base layer with as close to lossless quality as possible? I am playing with two at the moment, but not sure if those are the best options if I want to focus on quality.quietvoid wrote: Fri May 12, 2023 11:03 amReinjecting the *original* RPU is wrong.

I don't know but you need to stick with HEVC if you want to reinject the RPU.danbez wrote: Fri May 12, 2023 5:40 pm What would be a good FFMPEG command line to create the new base layer with as close to lossless quality as possible?

Conversion to MEL doesn't remove anything.NiCE77 wrote: Sat May 13, 2023 5:22 amIf the device will play Profile 7 MEL, would there be an advantage to choosing mode 1 (converts the RPU to be MEL compatible)?
Will this also remove the mapping metadata and NLQ? If not, how will the end result still be good?
Probably.NiCE77 wrote: Sat May 13, 2023 5:22 amAnother question:
Dune / Zidoo / Zappiti will also play the Profile 7 FEL files with the EL skipped, but I see RPU response in the test file (blinking colors). Is this also the wrong method used by these vendors?
Thank you, can you give me some movie titles where FEL has mapping metadata?quietvoid wrote: Sat May 13, 2023 2:12 pmConversion to MEL doesn't remove anything.NiCE77 wrote: Sat May 13, 2023 5:22 amIf the device will play Profile 7 MEL, would there be an advantage to choosing mode 1 (converts the RPU to be MEL compatible)?

So if the title is FEL the result can be wrong.

It's only an issue when FEL has mapping metadata that affects the image a lot, because the intermediate image is not correct without the EL.
Not sure, you can look at the FEL required list RESET_9999 made.NiCE77 wrote: Mon May 15, 2023 5:22 am Thank you, can you give me some movie titles where FEL has mapping metadata?
