Dolby Vision now possible through MP4 Mux.

How does the latest firmware mess up the DV black level? I read forums posts and thought only hdr10 still had problems.

There's a glow, and when you use the new near black option to fix it, it crushes black but the avsforum is full of moron who use the vivid mode so it's hard to follow.
On the old firmware I'm using, there's no glow and no crush, at least not in cmv4.0.

Can't WAIT to see what WebOS 25 does to my G2. Oh, right, I'm GOING to wait cause it scares me. LOL

[RESET_9999]

it will most likely allow DV mkv support in plex

Sigh. So it's the same situation as my a95l after a firmware update. I start to think this glow is mandated by Dolby themselves.
DV on my C9 looks better than the a95l in dark scenes, which is mad. We're going backwards.

I do have a query, I note every one mentions Plex with regards to the UGOOS AM6B+, will it run Jellyfin and still support dovi?

Not a fan of plex, I have a tonne of media and don't see why I should have to subscribe to watch it in High Res

[RESET_9999]

If there’s a Kodi add-on, then yes. Plex, Jellyfin, and Emby are only used as servers for your movie library and Kodi is what actually plays the movie on the Ugoos and you can configure your home page as you want. BTW, Plex only requires a subscription for remote streaming; local streaming is completely free. The best option, IMO, is to configure SMB access, it’s much faster and more stable than any add-on.

I'm having some "fun" injecting HDR10+ and/or DV RPU into HDR10 remuxes and if my understanding is right, for HDR10+ I have to ensure that source & target files have these props matching:

Code: Select all

Mastering display color primaries        : Display P3
Mastering display luminance              : min: 0.0050 cd/m2, max: 1000 cd/m2

And, if present:

Code: Select all

Maximum Content Light Level              : 1 000 cd/m2
Maximum Frame-Average Light Level        : 156 cd/m2

Besides, of course, video resolution.
Does this make sense?

For DV profile 5 source files is there anything besides resolution I should check to ensure there is compatibility between the two? Anything I can check on RPU itself except for frame sync?

[RESET_9999]

the static metadata doesn’t matter much. The only accurate way to confirm that they’re the same grade is to measure the pixels of each video(with madvr) and, optionally, do some screenshot comparisons.

Example, The.Exorcist.1973 DV P5 vs UHD-BD:

Watched the tutorial and I'll have a lot to study. Thank you for sharing that.

So basically I've been extracting HDR10+ and/or RPU, editing to sync frames accordingly if needed and calling it a day. Never generated or watched a plot.
Sounds like I gotta start over. Silly me...

Quick checklist of things to remember/ignore:
- Don't give a damn about what MediaInfo says about color primaries, luminance or MaxCLL/MaxFALL.
- Rely on frame-by-frame comparison.
- Rely on graphs.

Situation for HDR10+ should be specular 1:1.
Correct me if I'm wrong.

Sounds about right.

When I started off, I bookmarked his tutorial videos for easy reference. I rewatch them when I get confused or have questions. 99% of the time, my questions are answered in the videos. His DV explanation videos are great too.

I also use his spreadsheet as well as his DV movie brightness folder (I recommend using JDownloader as google drive search sucks.)

Reset doesn't advertise this enough IMO, but for a small donation you get access to his huge RPU collection. (JDownloader reports more than 2200 RPUs!) Extremely worth it, and he very much deserves it, considering the significant public service he has provided in the DV space.
