Dolby Vision now possible through MP4 Mux.

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)?

You use the original profile 7 RPU for DoViBaker.
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.

Thanks, 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?

Reinjecting the *original* RPU is wrong. When converted to profile 8.1 it is fine.
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.

ffmpeg -i "example.avs" -c:v libaom-av1 -crf 23 -pix_fmt yuv444p12le av1_test.mkv --> AV1 output

ffmpeg -i "example.avs" -x265-params "hdr10-opt=1:chromaloc=2:range=limited:output-depth=10:profile=main10:level-idc=5.1:colorprim=bt2020:colormatrix=bt2020nc:transfer=smpte2084:hdr10=1:max-cll=0,0:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)" "out10.hevc"

If i convert a DV movie to mkv (using HandBrake or DVDFab, without DV, just normal HDR), and then put the movie in tsMuxer, add the DV video, and then create a Bluray folder or ISO, the DV works?

I don't know but you need to stick with HEVC if you want to reinject the RPU.

If 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?

Another 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?

Conversion to MEL doesn't remove anything.
So if the title is FEL the result can be wrong.

Probably.
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.

Is the FEL issue with Saving Private Ryan limited to just the US release or does it impact all the other regions (like UK, Australia, Canada)? Curious if trying another disc from a different country would produce similar results

Thank you, can you give me some movie titles where FEL has mapping metadata?

Not sure, you can look at the FEL required list RESET_9999 made.

I did as you said. Disabled mux in bat.

I want to generate dolby vision from remux HDR10 to remux dolby vision with your scripts and tools , is it good idea or this is not good at all and better not to be done ?

3-1 for that but I recommend generating DV in Resolve which use the official Dolby algo. There's a tutorial video link somewhere in my signature link.

This problem is observed only on Disney+ and Netflix web-dl and only when playing over the network (NAS or DLNA PC), if run via usb, everything will work. If RESET_9999 knows the treatment method, it will be great, but as far as I know, when building mp4box, it will not be possible to make a working version, you need to build using ffmpeg

Hi, I've found what the issue is with Disney+ (at least with ffmepg), it's the presence of chapters in mkv file (which get copied to mp4).
-map_chapters -1 does the trick with ffmpeg.

This is the full command i used:

Code: Select all

ffmpeg -i "video.mkv" -map 0:v -map 0:a -map 0:s:0 -map_chapters -1 -c:v copy -c:a copy -c:s mov_text -strict unofficial "video.mp4"

This will work for every non profile 7 video on LG TVs (have to try with profile 7 FEL's, but if I remember correctly, it won't work).
