I saw a bit of discussion on this up thread, is there an explanation for why cm_analyze gradually slows down during its analysis in the 3-1 workflow, with the effective fps rate gradually dropping? Happens with every title I've done so far (I'm using Win 10).

thanks for that, saves me the trouble of more tinkering with my set-up to try and fix it. Will watch the thread with interest to see if a fix is available in due course.

Hmm, that's strange. I wonder what it is then? Maybe there are multiple cases where RPU ends up incomplete? I'll make a bug report post one day if I have time and figure out the pattern. Do you know if quietvoid uses makeMKV and could advise at all?
There have been many different issues in the past:
- Non synced BL/EL
- Different M2TS/container timestamps

They are all authoring problems.

Usually MakeMKV reports errors but for some people it never does.
This one looks different since the metadata is randomly missing across the whole title?

Hi is there a way to speed up MadVR plotting? it just takes a long time even on a i9-13900k, Hope you all can help, Thanks

EDIT: I Figured it out I had to setup LAVFilters. Thanks

I've converted several HDR10 titles to DV using the 6-2 and 3-1 workflows and have been pleased with the results. With 6-2 I've been selecting "n" for exclude letterbox for estimating MaxFALL due to the warning about processing time. To what extent might this impact the end result? I only want to convert my library once, so don't want to take short-cuts if they are undermining final quality.
if you just use 6-2 to create a shot list for 3-1 it doesn't matter.

Why is MaxCLL calculated with DaVinci Resolve so different than MadVR? What is the most accurate?
different algo
Reset what you think about relise of wolverine and deadpool from kaleidascape striming resource which is on torrents now ?

Good afternoon, how can you be so sure, how did you manage to recognize it? I want to look into this issue, the Chinese SasukeducK has not yet given clear answers. Yesterday I did a little analysis of track 7.1, all the channels are different there, i.e. the side and rear are different, there is no way to take 7.1 from where, either he converted TrueHD Atmos 7.1 from Kaleidescape to eac3 7.1 or decomposed eac3 5.1 768 atmos into 16 channels and slipped a couple of channels of effects into this 7.1, to mislead everyone.
(Sorry for my English, translated by google)

Because the pixels are 1:1 identical to the Movie Anywhere Web-dl. This is not possible and this group has a history of faking web-dl.
Also, if you really can crack / web-dl KS, why not offer the TrueHD Atmos track as well?

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?

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...

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.
