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

Excellent, it worked. I am getting a greater understanding of these matters. Thanks.

Perhaps it has been already discussed, but I cannot solve the following problem. I have a hybrid MKV video (DV + HDR10) 3840X1608. My old LG C8 shows the file in HDR10 with black bars - all OK. So to play DV, I converted the file into m2ts - now my LG shows it in DV, all OK, BUT the top & bottom bars are no longer black, they are grayish.

So I extracted the RPU & adjusted the top/bottom borders manually to 276 & injected them back into the video. Nothing changed - the bars are still not black, but grey.
Is there a solution? Please help.

Forgot to mention: I play the video with OPPO clone

BTW Great tool! Many thanks!!

But then I found an app that was my "Saviour", and it's not DDVT.

Can you send me the name of the app please? I too struggle with my older LG TV

What's the model of your LG?
You can use the DDVT_MKVTOMP4 with Option 2 (Fake P5) enabled.

LG C8. I have tried the Fake P5 option also. To my surprise it did not work, I just get a black screen with sound. Somebody in this thread stated that old LG's have problems with new MP4 containers.

Converting MKV to M2TS works fine for me for files 3840x2160. If the video stream is "thinner" (like 3840X1600) then I get grey (not black) bars - this is very annoying if watching in a dark room. I understand that it is happening because DV metadata is not limited just to the video size, it is applied to the whole screen. I want to find a way to change this

When injecting the RPU it says video input matches with output RPU but RPU input does NOT match with video.

I also read that:

So, does that mean that since the final result here WILL have black borders I do NOT need to crop?
I 'fear' the RPU will not be applied to the middle where the picture is but starts at the top so that the black bars will get DV.
Or WILL it be centered?

edit:
Made a json file where it specifies the crop, but it doesn't take over the values.

Hey, I have a question about your post. I sent you a private message about this. I would appreciate an answer! Thx.

The active Area 0,276,0,276 is wrong if the input video is cropped and has no borders. set the Active Area to 0,0,0,0 in this case. Active borders must set for the real resolution of video file, not the aspect ratio. Also the OPPO and his clone have problems with cropped content. I recommend Ugoos AM6b+ / Dune Homatics 4K R Plus Media Player with CoreELEC CPM builds. You have full FEL support with this Media Box and no problems with cropped content. The player plays MKV P7 FEL Single layer files without re-containering, too.

So, does that mean that since the final result here WILL have black borders I do NOT need to crop?

It's easy, simply ignore resolution/AR from DV input file. Important is the resolution and the black borders of the HDR target file where you inject the RPU. If your target file is an UHD with 3840x2160 and has 276px Black borders Top/Bottom and your input file with the DV content has 3840x1600 without black borders, set the Active Area to 0,276,0,276.

-v0.65.2
-FIXED Errors with FFMPEG and bitstream demuxing/pipelining (clipping and wrong colors on some movies)
*Minor Bugfixes.

[pejok]

Hi all,

I get below errors when using HYBRID script. Last version without this errors is 0.64.2.
There are no errors with exact same video files in DEMUXER or INJECTOR -> It demux and inject without any issues and final video file is OK.
It occurs with every video file, when i try to use HYBRID script. Source video file for demuxing has both RPU and HDR10+ .json as well.
Where should be the problem or what should i try to set up/change on my side?

OS: Win 11 Pro, 24H2

Thank you very much. Excellent tool

[-QfG-]

@pejok Problem fixed, please download this file and overwrite the hybrid script with this file:

[pejok]

@-QfG- thank you, no errors so far but maybe last bug as i noticed is, while testing and trying to do hybrid with HDR10 only file + DV&HDR10+ file:

- tool correctly fetch all info about the files
- i have set also to inject HDR10+
- start the script -> DV extracted -> HDR10+ -> Scenecuts fixed -> DV injected -> muxing final video file
- injecting of HDR10+ completely ignored
- final video file contains DV + HDR10 only (not HDR10+)

You're right, sorry forgot to process this switch. Fixed now, simply update the script.

[pejok]

Perfectly working again. THANK YOU !

Strange. I have an LG B8 and the files play without any issue when they are converted to "fake" Profile 5.

Thank you for your continued efforts on improving these scripts! They have saved me so much storage by only needing 1 file that will play on pretty much anything.

Is it recommended to download the latest scripts from your github site and unzip them into the folder containing the full DDVT package, overwriting the original scripts from the Mega download? I see that 65.2 is the latest on Mega but the github scripts are showing as 65.3. Are there any gotchas like needing updates to other apps in the Tools folder?

For all:

I am experiencing a related issue - drag 'n drop is no longer working on the main Win 11 PC I use to run these scripts. A Win 11 VM running the same Win version does still work. I've been trying various recommended solutions (13 of them so far) but all I've managed is being able to drag 'n drop ONLY to the Desktop.

Not to open apps/windows/websites with a drag 'n drop function. Plus I can only drag to the sides or bottom, not up past the explorer window title bar - that just drops the item being dragged just like pressing the ESC key while dragging. If anyone else has experienced this and fixed it, I'd be grateful if you shared your solution. Right now it's looking like a full Win re-install, which I'm reluctant to do.

I can still use cut & paste to 'drop' the source files into the scripts, but drag 'n drop is preferred.

Maybe this helps, Ramesh Srinivasans fix helped on my Win10 too:

Thanks, but no-go. I hadn't come across this particular registry fix, but mine was already set properly for that Attributes key, and the other key in HKCU was not present.

I'm going to try removing the shell extensions for DDVT and clearing the registry of any DDVT specific keys. And then I'll try a fresh folder with the latest package and retry adding the shell extensions. If that fails, I'm going to reluctantly do the full fresh Win install.
