It occurs only with mp4 files? I've only could test mkv files.
I'll also test it with this scene, but it will be with a mkv file.
i only do mp4 for plex for myself, no mkv on the server at all so i can only say it happens with mp4 for me

it doesn't happen 100% of the time, but enough I was able to notice + reproduce it at that scene, I think it was from FF/RW on my end too

this was also end of 2021/start of 2022

chromecast is at a different 1080p tv since then so i dunno if an update since fixed it totally or just some more or whatever

Can someone help me out, I was under the impression that Makemkv can now do a remux in MKV with DV. Do I need to do more than Makemkv to get this to work. I am currently ripping Jurassic World, playback will be on a Zidoo Z9X and potentially a Shield. Thanks

EDIT## Hmmm, maybe I am confused, I found the google drive links with the DoVi scripts, but the Ziddo is displaying DV from a straight rip.

Ran into some files that have "SMPTE ST 2094 App 4" which is described as "It is a 3 point curve instead of a 10 point curve though. Essentially a pre-release version of HDR10+ Profile B."

The script is not able to convert it to DV, and it fails entirely and won't generate via madVR. Any chance of getting that to work?

Feel free to DM and I can link you to a sample.

Hi, MakeMKV can do a remux from a UHD DoVi FEL/MEL disc (dual track/dual layer) to a mkv file DoVi FEL/MEL 7.06 (single track/dual layer). The rip is perfect with no loss in quality.

You don't need any other software, but you'll need a device capable of playing this kind of file and processing DoVi in the right way, specially FEL, which is more difficult.

Read this thread patiently, it's plenty of reviews about every device.

Ok, so now it's mainly corrected for your actual setup.

I have tested this scene using FF/RW and couldn't see any artifact.

RESET_9999, I've seen and downloaded the new DoVi test files, but I don't know what means the L1, L2, L3, L8 terms, please could explain to me in short or redirect to any post which explain it so I could test in my Chromecast with Google TV.
Thanks in advance.

Thanks. I'll test it and report here.

Someone corrects me if I'm wrong but if the hdr10plus file doesnt say profile B or A, the metadata are incomplete/corrupted and can't be parsed so it can't be converted to DV.
madVR should be able to generate DV though.

Yes you can just play makemkv rip straight with the zidoo but you may experience some flickering/flashes with FEL movies so the best option is to convert to profile 8.

Replying to clarify it is SMTP 2094 App 4 Version 0 (not 1 or 2).

Option 3-1-1 (HDR10+ or madVR) is failing:

Code: Select all

File doesn't contain dynamic metadata, stopping.
Parsing HDR10+ JSON file...
Error: The system cannot find the file specified. (os error 2)
Press any key to continue . . .
Then it tries to parse a non-existent RPU and fails entirely.

Yes I know exactly what you're talking about, I had to deal with it on Amazon Upload Season 01.
But now I understand why madvr won't work. Since I merged the hdr10plus and madvr workflows together, the script detects "SMTP 2094" as hdr10plus regardless of the profile (0,A or B).
I'll fix it in the next version but right now you can just add this code at line 8056 (assuming you're trying workflow #1) and it should fallback to madvr if HDR10plus extraction fails.

Code: Select all

if NOT ["%errorlevel%"]==["0"]  goto :no.hdr10plus
Please forgive my English.

Version 0 can be parsed by using --skip-validation when parsing HDR10+, in the latest version.

@quietvoid
great. thank you!

@rophel
will be fixed in the next version but if you want it now then add this code at line 8054 (and update the hdr10plus tool)

Code: Select all

if NOT ["%errorlevel%"]==["0"] echo VERSION 0 detected & "%hdr10plus_parser_path%" --skip-validation extract %HDR% -o "%TEMP%hdr10plus.JSON"

Tests made on Chromecast with Google TV over both TV-LED and Player-LED modes.
I have played the eight "RPU p8.1/4 L1.L2..._cmv29/cmv40" files.

I can't see any change in picture in L2_trim_chroma_weight, L2_ms_weight, nor any L3 and L8 tests.

Please, can you explain to me what this means? It suposses any problem to Dolby Vision FEL/MEL processing on this device?

Thanks in advance RESET_9999.

We've just discovered a bug withe Zidoo Z9X Dolby Vision output. Using the DV test pattern from here:

https://www.biaslighting.com/products/s ... -reference

the Zidoo Z9X will only resolve black levels down to 85. The Nvidia Shield has been tested and it correctly resolves all the way down to 64, as does my LG C9 internal player. It would be interesting to see which devices pass the test and which ones don't.

Sadly real world viewing shows this problem as posterisation in dark scenes and is very distracting.

This is expected and it means the CCwGTV (or your TV, but unlikely as you said it's the same in player-led mode) only supports CM v2.9 Dolby Vision.

That pattern isn't free but we've had it for a while and it just shows some issues with HDMI input devices.
I thought the Shield also had the issue, though.
The FireTV Stick 4K (2018 and 2021) clips at 72 on LG C8-C2, assuming your pattern is the same as what we've had.

You can try the same pattern but with modified metadata from RESET_9999's test files: black.levels.pattern.modified_3079.ts
If that improves the black clipping, then it's the same issue.

interesting...
x800m2 is crushed/clipped at 72-73 on the C8 but on the C2, it's perfect, I can see 65/66.

on another topic:
@to anyone doing Hybrid P8 remux, I started an excel sheet listing the movies that can(or can't) be injected:
