[DDVT Tool] Dolby Vision RPU Demuxing / Injecting / Editing. - Page 39

It obviously was not tagged correctly. If it is Dolby Vision tagged, Media Info says Dolby Vision.

von Suppé · 25th October 2023, 12:44

On a non-DoVi device the colors being purple/green would indeed suggest the file being DoVi P5. I think @Atlantis has a point. To which I notice both 23.976 framerates where one stating 23976/1000. Which suspects me ffmpeg being involved in flawed container muxing.
Try importing and remuxing the file with MKVToolNix. When muxing Dolby Vision mkv, always force-set "Default duration/FPS" to the proper value; in your case being 24000/1001p. See if the file turns out allright in MediaInfo.
Note that even when tagged properly, a P5 DoVi file always turns up purple/green on a non-DoVi device. P5 offers no fallback video like other profiles because of Dolby's proprietary colorspace being used.

Can you convert RPU to HDR10+ metadata and if yes what command to use?

Nope. Only HDR10+ Json to DV RPU.

Atlantis · 25th October 2023, 17:58

Wow, ok. I thought it should be the other way around! Since HDR10+ is an open standard I thought it should be possible to convert to something open!

So, basically, all I am trying to do is pull the DV data from a REMUX, then inject it into an encode. Is this possible? I tried to use DDVT Demuxer to extract the RPU, which was successful. I then tried running the DDVT Injector to inject it into the encode of that same REMUX, but it creates a raw BL+RPU.hevc. I tried bringing that hevc file into MKVToolnix to convert it over to a .mkv and re-add all the audio tracks and subs, but the file looks to still be missing DV info. When I check the Medianfo, it is just the HDR10 data.

Are you able to push the DV RPU into another .mkv and just mux in the DV data, or am I looking at this all wrong?

Out of interest... What make/model of playback device and display do you have?

von Suppé · 26th October 2023, 15:10

REMUX is a common phrase and it's possible the file contains Profile 7 DoVi.

The demuxer script tells you what profile is found after having analyzed the input. If P7 is found, you must set CONVERT RPU to PROFILE 8.1 HDR. Such is used to inject into a single HDR HEVC video. Note that if your recode has no black bars, you also have to set CROP RPU to YES.
I am assuming here the recode has the same frames & framecount as the source.

Yeah, that part seems to work, and it does export a .RPU to a temp folder. I guess I am confused on how to mix this .RPU into another file. I basically encoded the REMUX down to a smaller size and I am looking to mix the DV data into it.

When you watch the file in MediaInfo in basic mode, it does NOT show Dolby Vision. It only shows Dolby Vision if you go into detail in MediaInfo.

Also in Injector you can choose output to MKV.

Yeah, I am looking at Medianfo's Text view. I have one video track with just HDR10, and this was the .hevc that was output from DDTV Injector.

So, I think I am missing something..

Are you using an old version of mkvtoolnix?

I mux the BL+RPU file with mkvtoolnix frequently, and the resulting mkv file always shows DV and HDR10 info.

Also mediainfo must be recent version.

Simply use the DDVT_Hybrid script for this. Open the script and paste the ENCODE in the First HDR Input Video. Second Step: Paste the REMUX now in the second DV Input Video. Check the Menu if all settings are correct. Now mux the DV RPU into the ENCODE. Done.

Atlantis · 26th October 2023, 21:39

Output as MKV as I always do.

-QfG- · 27th October 2023, 22:38

Yes. You can always use mkv output.

von Suppé · 28th October 2023, 11:14

I'm getting confused about MediaInfo here.
Would someone please confirm me either right or wrong in thinking MediaInfo only shows Dolby Vision when in-container, and not in elementary stream? For DoVi, I've always presumed it relied on metadata written on container-level.

Mediainfo will not show any DV info until you have muxed the BL+RPU file into a mkv file.

At least that is what it does here.

von Suppé · 28th October 2023, 18:55

My presumption was correct then. Thanks for confirming, rco133.

Is there a way to convert DV level 8.1 to level 7 for Blu-ray?

DDVT Tool can convert DV 8 to 7, but after that what should I do to create a compliant UHD Blu-ray disc with a MEL DV?

Atlantis · 30th October 2023, 17:19

Is it possible to set the default output to mkv in Injector? I want to avoid to change it every time.
