How do I know before downloading?
You can do quick read using 2-2 before downloading the whole thing, just make sure you download in sequential order if bittorrent

Edit:

I just quick checked the Blue.Beetle.2023.2160p.MA.WEB-DL.DDP5.1.Atmos.DV.HDR.H.265-FLUX and it's P8 CMv4.0

Code: Select all

  "rpu_data_crc32": 2385106521
}
Parsing RPU file...

Summary:
  Frames: 576
  Profile: 8
  DM version: 2 (CM v4.0)
  Scene/shot count: 3
  RPU mastering display: 0.0001/1000 nits
  RPU content light level (L1): MaxCLL: 729.26 nits, MaxFALL: 24.93 nits
  L6 metadata: Mastering display: 0.0001/1000 nits. MaxCLL: 0 nits, MaxFALL: 0 nits
  L2 trims: 100 nits, 600 nits, 1000 nits
  L8 trims: 100 nits
  L5 Left offset: 0
  L5 Right offset: 0
  L5 Top offset: 278
  L5 Bottom offset: 278
  HDR10 BL MDL: min: 0.0001 cd/m2, max: 1000 cd/m2
  HDR10 BL MDP: Display P3
  Resolution: 3840 x 2160
  FrameRate: 23.976fps
btw @RESET_9999, what RPU is better to transfer from WEB, P5 or P8? Does it even matter if L3L8L9 data is the same on both RPUs? Asking because the P5 RPU bin file is 36 MiB larger than the P8 RPU for Dune: Part Two

Sorry my bad. I just rechecked and the version I downloaded was Blue.Beetle.2023.2160p.WEB-DL.DDP5.1.Atmos.DV.HDR.H.265-XEBEC[TGx], not Blue.Beetle.2023.2160p.MA.WEB-DL.DDP5.1.Atmos.DV.HDR.H.265-FLUX. And thanks for the tip to check before the download is finished.

Any idea on the first question regarding how to check whether the release is from itunes or disney+?

again, quick 2-2 and check the RPU for "Level4": line, but I believe IMAX version is the one you need
also, DSNP means Disney Plus...

and another question @RESET_9999 - why does it matter whether the RPU has L4 if we only transfer L3L8L9?

Just checked the first file (the higher bitrate one) and there's no Level4 line, along with these:
L5 Left offset: L5_is_missing_you_should_edit...
L5 Right offset: L5_is_missing_you_should_edit...
L5 Top offset: L5_is_missing_you_should_edit...
L5 Bottom offset: L5_is_missing_you_should_edit...


I'm downloading the second file to check. It's currently at 17% already but dragging it into dovi scripts still shows nothing.

Btw, do you know why there's WARNING at the beginning of the dovi scripts when I open it and does it matter for this particular cmv4.0-to-2.9 workflow? I already downloaded and installed all the tools per tutorial.

If a movie is not in any of the red/green/yellow list in your spreadsheet, e. g. Creed III, does it mean this transfer process won't work or you haven't tested with that movie yet?
I haven't checked all the movies
I just tried with another movie (Blue Beetle 2023) and the stream file I download turned out to be cmv2.9, not 4.0 :shock: (Blue.Beetle.2023.2160p.MA.WEB-DL.DDP5.1.Atmos.DV.HDR.H.265-FLUX)
My cmv4.0 source for this movie is MAX and not MA(movie anywhere)
How do I know before downloading?
you cant
I then tried Aquaman and the Lost Kingdom 2023 and it was cmv4.0 but I realize some numbers on my L1 plot are different compared to yours:
I edit L6 when I do P8 hybrid. It doesn't really matter, these values are ignored in DV.

L4 is when I do P8 hybrid, it doesn't matter when you transfer 3-8-9 to a P7 rpu since they already have L4.
All iTunes webdl are missing L4 and L5

It just means your tool pack is missing the Dolby professional tools. It doesn't matter for 2-6 but you can get them for free here:

Does anyone using the Ugoos AM6B+ have a white banding issue in Saving Private Ryan @ 2h35m mark?

Can you provide a photo? I don't have the movie but I may try later.

Does it matter if I use a different source from yours and at the end it passes all the checks?

I compared the L1 plot of my Blue Beetles 2023 (source: MA) to the L1 plot of yours (source: MAX) and they were exactly the same, except for some numbers (red circles):

Hi everyone, some time ago I asked if anybody here knew how to change maxcll and maxfall values within the hevc stream itslef without the need to re-encode it. Well ,I've finally figured it out.
Thus, a question comes to my mind: how important are these values in the actual playblack? I've seen many movies having those values wrong and sometimes not having them at all.

They don't matter for DV playback for sure, and possibly not in some contexts even for HDR fallback, as Paramount for example continues to not add MDL metadata for their UHD BDs. Curious what the method you figured out is, regardless, please share if you're willing to. Thank you kindly. Cheers. :)

L4 is when I do P8 hybrid, it doesn't matter when you transfer 3-8-9 to a P7 rpu since they already have L4.
All iTunes webdl are missing L4 and L5
So, just to confirm: profile 8 itunes web-dl releases are now perfectly usable right? What about profile 5 itunes web-dl releases? Should I avoid them because of the color error (mentioned in your spreadsheet: color difference(orangish red) is caused by apple stupid static color reshaping in the RPU. Once removed (when converted to P8), the colors match.)?

Sorry, by "all the checks" I only meant the checks I see at the end of the Transfer CMV4.0 bloc video tutorial. Are there other checks I should do, considering I'm using a difference source, like brightness difference, color error, etc.?

the apple color reshaping metadata only applies to DV profile 5 playback. The dolby visions levels (1-2-3-4-5-6-8-9-11) are a different thing and are always the same regardless of the DV profile so yes, any cmv4.0 rpu can be transfered to a cmv2.9 rpu as long as they come from the same DV analysis (same L1/L2).
Is there a way for me to check them myself or is it too complicated?
just download the webdl and check if it's cmv4.0 and the same Level 1 as the bluray disc DV ?

all that matters is the metadata themselve. It can work only if they are the same

Thanks again for all the explanation so far.

I'm checking frame difference for Blue Beetles 2023. Doing it manually by looking at random scene cuts in Avisynth+ and I'm seeing 0 frame difference. Yet the L1 plots between the original bluray and stream version are not in synced (ignore the red circles please). What could be the reason?

as I said earlier, what matters is that your scene cuts match the BL. The framecount mismatch makes the graph look different.
