sure 10 000nits is bright but it's nothing compared to real-life highlights.
I think grading at 10 000nits(or maybe at least 4000) is a good idea as long as you also do the DV trim passes for low-nits TVs.
Because you can keep the highest dynamic range possible and your grade is future-proof for when there are brighter TVs. (eg no need to re-grade the movie in 10 years when all the TVs are 4000nits capable)
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.

PROFILE 7 DOLBY VISION SINGLE-TRACK DUAL-LAYER FEL SUPPORT: YES.
- It plays M2TS & TS & MP4 & MKV totally stable. Tested from begining to end of 150 minutes mkv files.
- Only with some files, FEL goes out of sync randomly if you FF/RW or jump to a concrete scene. It seems it's related with the version of MakeMKV or software used.
- FEL never goes out of sync if you resume a video.
- Compared with internal TV player colors are perfectly accurate.
Sync issue sometimes occurs with my CCwGTV and Plex and mp4 FEL files too

The one I use to test myself for this is Mission Impossible Fallout - at the start of the film when they're in the tunnel and get ambushed, the lights along the walls in the tunnel, the lights from the FEL layer will be superimposed over Tom Cruise's face or other wrong parts, very easy to distinguish with this scene and the lights if it's misaligned

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 made a mistake and my sentence weren't accurate, so I've changed my review:
- Only with some files, if you FF/RW or jump to a concrete scene it loose DoVi processing and stutters. It seems it's related with the version of MakeMKV or software used.
- I couldn't see FEL out of sync neither resuming nor FF/RW a video.

The chromecast is able to decode fel, isn’t it?

If It can send tv led signal , will
It be fel?

Hi all, I'll give my feedback for Chromecast with Google TV (aka CCwGTV) to "DoVi file playback support on devices" datasheet.
thanks I linked your review.

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.

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

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