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

[techdiver]

Cheers for the replies guys.

Another one that I have thought about is adding DV metadata from one release to say a ripped bluray remux. In some cases the duration of each mkv is different as as such I assume that a straight run of the hybrid script would not work correctly. I tested this and saw that for HDR10+ is was saying that since the timestamps are off it will ignore the metadata at the end of the file. But in the case where the difference is at the start of the file is there anything that can be done? I'm assuming no?

Hello.

When using "DDVT_MKVTOMP4.cmd" in version v0.61.4, information about HDR was lost; in version v0.60 there is no such problem.

I think, that no cropping informations in the RPU is the same how 0 entries. But i have no proof for this statement.

2. IMAX Format: You can do 3 Things:

1. Set all borders to 0 (this is the way that i use)
2. Set all borders to the lowest entry (Example: IMAX Scenes Borders 42/42, Normal Scenes Borders 272,272 -> set Borders to 42/42
3. For Freaks xd - Create a custom.json file and set all borders manually for IMAX / Normal frames. Good Luck In this case, don't forget to turn off border manipulation via the tool himself.

3. BORDERLESS VIDEO: If the video is cropped or full 16:9 without Black Bars, set all boreder entries to 0!

In my Tests i have no problems with RPUs with borders entries of 0 with cropped content. BUT ! I have trouble with RPUs with Border entries other than 0 by cropped (borderless) content!

In all cases it is recommended to set the correct borders in the RPU for maximal compatibility with the hardware players.

Does this still applies? So if i have a movie with mixed IMAX and normal widescreen content, do i set borders to 0? DDVT says top and bottom video border are 208 px and rpu top and bottom borders are 207 px.

Do i need to crop video borders to 0? or crop rpu? or both??

When adding DV or HDR10+ metadata you have to make sure that it's synced with the video stream, otherwise there'll be annoying artifacts (jumps in brightness). This is especially true when using sources from different medium, like digital vs. Blu-ray, as those are usually not synced because of some initial logo or something.

To check if the metadata is synced with the file you can use the FILEINFO script to get the scene cuts (frame numbers where scenes change, frame numbers starting from 0), and match that with the frame number in the actual video (I like using djv, though be careful since in it frame numbers start from 1, not 0). You can then apply the positive or negative delay in the INJECTOR script (I haven't used the HYBRID script but if it has a delay option you can use that too).

For mixed aspect ratio content I recommend leaving the RPU borders as they are, i.e. the border part should display something like "[LEAVE UNTOUCHED]". Another option would be to set the borders to the height of the smallest black bar (corresponding to the tallest scene(s)).

Excellent. Thanks for the reply!
