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

[GodzilaAvenger]

Hi,

With this custom.json file you are only applying the edits to the first 40 frames.

If the film's aspect ratio does not change you don't need a custom.json file, delete it and just use the INJECTOR script with the RPU and set the borders in the DDVT interface.

Hi GodzilaAvenger,
Thank you for the swift reply.

Unfortunately I already tried that, the results are the same

Below the settings that I used:

Step 1:


Step 2:


Step 3:


Step 4:


Result remains the same 3840x1600 pixels (cropped/same as source without cinematic black bars/borders)


What I wish to achieve is 3840x2160 pixels (aspect ratio remains the same but cinematic black bars/borders are added during the DDVT Injector process)


Again any help on the matter is greatly appreciated. Thanks

Ok, got it. DDVT can't letterbox a cropped .mkv file (add top and bottom black bars). It is only meant for handling dynamic metadata (Dolby Vision/HDR10+). If your .mkv file is 3840x1600, you should set the borders in the RPU to 0, as it originally was.

If you want to letterbox a video you need to use FFmpeg. For instance, see this and this on how to do it. If you do this and get a 3840x2160 .mkv, then you have to adjust the RPU borders as well (set top and bottom to 280).

Hi GodzilaAvenger,

I was under the assumption that it actually was possible, so I misunderstood/misread post #281 and #297

Meaning what I want to achieve is simply not possible without ffmpeg processing if the source is cropped 3840x1600 I will have to transcode it using ffmpeg filter to 3840x2160 pixels, which may result in loss of quality. Thanks for clarifying

[GodzilaAvenger]

I highly doubt letterboxing using FFmpeg would result in loss of quality. Even if it did, the loss would be imperceptible.

As the title suggests ???

I have just asked this question on the x265 thread

https://forum.doom9.org/showthread.p...16#post1987516

Does this make any sense to anyone here ??

Is there still and option to remove the HDR10 metadata ?? I could only see how to remove the DV metadata.

[von Suppé]

As TDS described in your linked thread, removing HDR metadata can render a device to not play the baselayer correctly. May I ask why you want to remove HDR metadata when video is HDR encoded?

TBH, I don't know if I need to be removing it, it's just that I am trying to figure out how to encode Dolby Vision, seems that most are Hybrid's.

Go here:- https://forum.doom9.org/showthread.p...77#post1987477 to see what I have been trying.

The difference between HDR Hybrid & and DV seems to be this :-

Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2086, HDR10 compatible

and

Dolby Vision, Version 1.0, dvhe.08.06

If nothing else it would make an interesting addition for the completists!

hi how to convert dolby vision to hdr10+? i have a samsung and i would really need it?

[hidef_rec]

Had asked that before; don't believe it's doable.

----------

Thanks @-QfG- for the new version. Just tried DDVT_HYBRID, but when I drag-and-drop a HDR file (my sample is HDR10+ w/o DV) or any HDR file, nothing happens, it doesn't drop in. Am I doing something wrong?

Triggering DV also depends on the playback device and video container. For example if I remember correctly DV playback on an LG TV's internal media player using .mkv is not possible and it has to be .mp4.

Correct. Although some people have had some level of success muxing Dolby Vision encoded content into .ts/.m2ts

You can not Remove "HDR Metadata" because they don't exist. HDR is a fixed included colorrange, you can remove only HDR10+ Metadata.

it looks so, that W11 don't support drag and drop I use W10 and have no problems with drag and drop. Will search for a solution.

There is no solution yet to doing this.

Out of interest...

Which 100GB (triple layer BDXL) 4K UHD disc movies do you have?
