Dolby Vision now possible through MP4 Mux.

Any idea how he faked the sound? Perhaps the second option that I suggested, or are there any other thoughts on this?

any audio can easily be upmixed and altered to make it look different. It's not that hard to do and it's not the first time this group upmix 5.1 to 7.1, he did it for non-KS rip too.
BTW, every time he gets caught he changes his name. He was ''WKS'' before and he once contacted me to know how to add generated HDR10plus and DV to his fake googleplay webdl.

Thank you, it's a pity if that's really the case.

It IS definitely the case. This all started back in the day when under the name WKS, they put out some Avatar 4K release out of the blue claiming it was from GPLAY with VP9 codec (which I even wondered if it was real?), but it was just a shitty upscale and faked, even if in an ironic twist, the final retail UHD BD was also upscaled, at least it was properly done. I think they also did it for Titanic before there was any sign of a real 4K stream or UHD BD, although that one might have actually come from some ruzzian forum tracker, I forget.

Either way, if it seems too good to be true (KS suddenly appearing or something that hasn't been announced or can't be found at the retail source, streaming or disc), probably is fake, and people should be more skeptical and not just accept this at face value, especially if it has the Suckduck name on it (or XFORCE, another name they used randomly for Deadpool "KS" tagged release). Some people care way too much about getting attention and fake respect online.

C. Audio track which you will have to convert to AC3. This is a hard line limitation- you need to use AC3!!!

And this, no offense, makes the entire solution moot for me. I'm not going back from DTA-MA/Dolby Atmos to ac3.

There's gotta be an mkv way of doing this, with HD audio. I currently have an mkv like this:

Code: Select all

1: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
2: h265/HEVC, 1080p24 /1.001 (16:9), 10 bits - Dolby Vision Enhancement Layer

But no DV is getting triggered on it. Is the muxing of the 2 channels, like MP4 Mux does, possible for mkv too?

[RESET_9999]

Yep, I just tried with makemkv and the RPU seems to go out of sync at frame 32982.
I did not watch it but the scene cuts seem fine if I demux with tsmuxer and use dovi_tool.exe to make the ST-DL hevc.

makemkv scene cuts (OOS): https://justpaste.it/a8i23
tsmuxer demux scene cuts: https://justpaste.it/cmmbn

and the rpu is missing frames and is 5kb smaller with makemkv: https://slow.pics/c/AbM7fpJV

another one: Mississippi.Burning.1988

Makemkv missing half of the metadata: https://slow.pics/c/XtZD09Hp
no issue with tsmuxer... I guess the makemkv output should always be double checked...

Another one: Late.Night.With.The.Devil.2023

It seems the German studios don't know how to author UHD DV disc...

[skull88]

Yeah, possibly Capelight or a 3rd party using some wonky tools or out of date authoring flow. The Second Sight GBR 4K UHD BD is coming shortly for Late Night with the Devil, so we'll see if that one has the issue with DV at all, likely will be fine and maybe better encoding overall.

This is weird hoping you guys might answer this I used the script to bake pacific rim uprising FEL and the file came out much smaller than what was started its 26GB is that normal it says crf 15 which I know is pretty much visually lossless I'm just confused by it. Hope you can help Thanks!

[skull88]

Some movies just compress very well, so I would guess it's fine. You could always run a 7-2 comparison with the script for your input vs. output encodes if you're unsure.

Ok thanks Ill do that then.

[RESET_9999]

With CRF, the encoding quality is always the same regardless of the final bitrate/size. Some movies require more bitrate (grain, fullscreen, bright) and some others less( dark, digital, letterbox)

@RESET_9999 I was taking a look at your the grade/master doc to check whether the WEB RPU for the movie The Bourne Legacy was injectable or not.
L1 is fine, but it seems like PQ differs between sources. Wouldn't such RPU, if injected, change the original creator intent?

PQ: https://slow.pics/c/tyiJdlBW

[RESET_9999]

thats apple stupid static color reshaping. All their DV contents have this difference: red always looks brighter/orangish. sometimes it's less apparent.
this static metadata is removed when you convert the rpu to P8. Apple has no respect to the creator's intent, I did a video about it on my youtube channel.
Never watch iTunes P5 web-dl if you care about accuracy, always convert it to P8.

[ragico]

What is Dolby Vision 10.1 profile associated to AV1 codec? And who is using it?
Thank you.

[LV8HD]

Is it necessary to edit RPU mastering display metadata (not L6) when injecting, or is it better to leave it as it is?

[RESET_9999]

never modify the RPU mastering display value (source pq) because dolby calculate the average pq and trims metadata quite differently according to the selected MDL.
