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

I tried to strip RPU. When dropping the file on DDVT_REMOVER I get "Profile 5 cannot be removed!"

It was the shortest I had on hand

Interesting, so it seems that my TV completely ignores the RPU and just plays back the BL, but your player recognizes the RPU and tries to interpret the BT.2020 colorspace as Profile 5, which results in those weird colors. Thanks for checking it out!

I'd be more than happy to donate to both of you. Just haven't seen a donation link anywhere.

And again, thank you for the L6 Demuxer script. Works as expected, and I am using the Match L6 option in Injector with successful hybrids as a result.

maybe 8.4 is working for people more recently if but this list is updated pretty often.

HDR Stream you have Profile 8.1
SDR Stream you have Profile 8.2
HLG Stream you have Profile 8.4

So you need an HLG Base layer and mux the Profile 8 RPU in it. I think this works.

Profile 5 is another thing, you have the IPT (IPTPQc2) colorspace not the BT.2020 there.
Therefore, no fallback to HDR with Profile 5, because no BT.2020 colorspace are used.

Does that mean I would need to use something like wswartzendruber/hlg-tools to convert to convert the HDR10 base stream to an HLG base stream?
Would I then convert the Profile 7 8.1 RPU to 8.4?

[-QfG-]

Yes, i think this works, you must simply test this. Simply mux the P8 RPU frum the 8.1 video int the HLG Stream.

There's no point in attempting to convert to profile 8.4 as Apple devices don't support the dynamic metadata.
The only way seems to be tricking the device into thinking the file is profile 5, there's some script on MakeMKV for that.

Does that work with MKV files too?
Link?

Unless I'm mistaken, quietvoid is refering to the scripts created by RESET_9999. You'll find the link "DoVi Scripts" in his signature.

A more in-depth guide also exists: https://www.avsforum.com/threads/app...ision.3252865/
I think it requires MP4 files as final video.

It's possible to extract the DoVi layer from a mkv to burn a bluray? I don't see the option in the script

Yes it is. But only if the MKV includes a profile 7 single layer HEVC file.

if you have a "REMUX" of an UHD, simply use the Demuxer and check the Options for Saving BL and EL (you can turn off RPU extracting, not needed for this operation). now you can Build a UHD with this, for example with TS-Muxer.

There's no point in attempting to convert to profile 8.4 as Apple devices don't support the dynamic metadata.

Thanks for this info quietvoid

I can add Apple DoVi Injection in future Updates.

Ok, thanks for the answer, I thought that it was possible to build a Bluray from a profile 8 or 5 also, but now I see that is not possible.

That would be awesome!
Could you do this for both MKV and MP4 containers so we can test both and use MKV in the future if that ends up working?
Thank you!

I just read through those posts and RESET_9999's scripts but I still don't understand.

Could someone clarify how I'd get started converting either a Profile 7 or Profile 8.1 file to this fake Profile 5?

Also, am I correct in understanding that these Profile 5 files are essentially using Rec2020 colorspace and the same RPU metadata as a Profile 8.1 file?

Thanks

Why don't you just give it a go? I'm not familiar with Apple devices, but seeing the script, I suggest trying to start with 7 (MP4_MUXER Workflows). Followed by 4 (Apple iOS compatible MP4).
From there choose further, depending on what kind of source-file, and output wishes.

How was this created? Was it some real Dolby Vision HLG show and someone just delayed RPU to check the applying of it?

Does BBC already Dopby vision hlg on satellites?

Hey, I'm trying to inject an RPU into a HDR file which has a VBR video stream. After injecting, the resulting MKV file has the video stream as CBR and the audio and video is super async.

Any ideas on how to fix this? Thanks!

[GodzilaAvenger]

Is there a way to add delay (positive or negative) to HDR10+ metadata, similar to what can be done for DV?

VBR? Maybe you mean VFR? It does not matter that it is VFR, RPU is frame numbers based.

[panni]

Yeah, VFR. Results in a CBR file with desync A/V.

Check the FPS on the MKV File. It's recommended to use the "Mux in Container" function. I think mediainfo shows you 25 FPS instead of 23,976.
