I'm not completely certain yet, but: The DV might be of service mid term, but long term I'd have to find a way around it and tame it otherwise anyway. Also, if I upgrade Starship Troopers, knowing myself, I might eventually want to upgrade all of them. As in Kwai and Groundhog as well - the others I already have anyway, but they gave me more reasons to or in case of Crouching Tiger will be an "accident" really. And not sure I want to go that route. The irony being that the itch is there already also because of said accident...

Had Sony put it in a nice package, I would've bit for sure. But I hate the Sony pop art - this isn't exactly ugly, but I really don't know what they were thinking re. Skeletor. Nothing and happened out of ignorance I guess.
I do hate.po-op art Steels although some look good by sheer luck.

As I do both physical and digital, 95% of these on digital are Dolby Vision from day 1 and the benefits that DV beings are noticeable on both my TVs on 90% of these movies. I do get the lectures about tone mapping but I can only go by what I see with my own eyes.

Think I already made up my mind to give this a try after passing Ghostbusters, Kwai, Dracula and MIB (I don't even know if it got DV) which I may get in future.

Weird halos/outlines around things starting at around 1:13:00 when they get to the planet. Really distracting is this present in other versions? Watching in DV.

EDIT it's some sort of problem with my system it seems

Do you have the old disc to compare?

I will check this timestamp later.

I don't see Disney doing it at all tbh. With how stingy they are on catalogue stuff I can imagine them going "well, we don't have domestic rights with this one anyway so why bother".

Since this is MEL (for sure), it'd be weird, if the DV introduces pq problems as in literal artefacts if I got that right.

Will be interesting to hear if others can confirm.

Godsdamnit!

@lgans316: can't wait for your feedback, once you've checked the timestamp! If you also find these halos, it's very likely, I'll see it myself. I own a UB9000...

My disc is already on the way. Pretty psyched about it!
Would be such a shame, if the DV layer were screwed up, the DV is WHY most people got this release in the first place!

The DolBy Vision looks great. I compared it to the hdr for a bit and it's a huge difference in my eyes. I think the LG Thinq app was not playing nice with Dolby Vision on my tv

Too lazy to check the old disc as I got another disc inside the player to watch later.

I did check the Dolby Vision stream on iTunes and couldn't spot anything weird between 1:13:00 and 1:14:00. Also compared it with the HDR10 stream on MoviesAnywhere and they looked almost identical except for a wee bit more colour depth and highlights a tad less blown out on the DV stream. Once again I am no expert so YMMV

LOL

the new DV 25th-anniversary disc has static L1 Dolby vision metadata...

see here for more DV plot graphs:

What software you used for this?

Is this specific to this disc or apply to the ones released by Sony recently with DV grade (Kwai, Ghostbusters and Dracula)?

The main question is how does the DV grade look in your own equipment irrespective of what's stuffed inside?

For the record, I don't own any of the Sony regrades except Karate Kid. I didn't buy as they are expensive and I already got the old disc and the DV streams on iTunes.

it is specific to this release but it's not the first time I see a DV release with static metadata(Moonfall is one that comes to mind). The point of DV is that the TV receives information for each shot about brightness and therefore can tone map all the shots more accurately. When the DV metadata is static like this BD, it's basically like having a static HDR10 video with a maxcll set to 650nits.
FYI, the itunes DV stream has exactly the same static metadata.

the method is not super easy if you're not familiar with python:
You have to rip the disc to mkv, extract the DV layer, extract the DV rpu (metadata) and plot the graph with a script.

lol indeed if true. Not at people getting a better picture with the new disc (the Dolby Vision engine might still produce the better image after all), but at the "dynamic" meta data. Which other than not being very dynamic also has "interesting" values going by the old disc (which I assume to be basically the same HDR wise only with better compression).

Got it. So this pattern will apply to MEL only right?

Regarding itunes DV stream has exactly the same static metadata, thanks for the clarification. All I have is Apple TV Developer HUD and based on my comparison, I have said above that they almost look identical except for DV having a bit more nuanced colours and a bit less blown out highlights but again I don't know if its due to the metadata or my TV but my observation still holds good on both my TVs (77A80J and 65ZD9).

I am familiar with Python and Java but for enterprise grade development.

Moonfall is FEL but has static metadata. It can apply to any DV stream (fel/mel or streaming p5).

yes, that is expected since the HDR10 base layer is much brighter(maxcll=4342nits) than the static 650nits DV max_pq.

Also, streaming services use a more efficient colorspace which is the equivalent of YCbCr 11.5bits.

No wonder DV resolves the Light Cannon issue:

HDR10 MaxFALL = 2342 nits

Dolby Vision MaxFALL = 124 nits

The real question is why they choose to set HDR10 metadata so high??

Makes no sense to me...

As we are hot on this topic:

https://www.hdnumerique.com/dossiers...y-sonic-2.html

On the UB820, think it was showing 2100 nits MaxCLL and MaxFALL 281 nits

However, the site says this:

In HDR10, the brightness level of the brightest pixel in the entire stream (MaxCLL) is 298 nits. An average value of brightness peaks was measured at 534 nits. Similarly, on the entire feature film, 97.73% of the shots are composed of highlights (with a median of 169 nits) . Regarding HEVC video compression, the average bitrate was measured at 41781 kbps and 45645 kbps (with Dolby Vision overlay).

and yours https://drive.google.com/file/d/13D2...ew?usp=sharing

So which one is correct?

well the DV metadatas are inaccurate. This is not how the average DV plot should looks like. To me, it looks like the studios went cheap and decided to take shortcuts and set a static L1/L2 instead of grading DV shot by shot properly.

When they grade DV properly, they run the Dolby algorithm to generate L1 metadata which measure and maps all the pixels of the actual HDR grade. It creates a min_pq, max_pq and avg_pq for EACH SHOT. L1 should never lie to the TV like it does in this BD. The brightness adaptation to different displays is done in the L2 trim passes, not L1 which is what the graph plot is.

Then they do the time-consuming part of the DV creation: the L2 trim passes where they have to go shot by shot again and adjust everything for different brightness outputs (usually 100/600/1000nits trims). This is the metadata your TV use to adapt the content to its internal capabilities.

In other words, using static L1/L2 metadata makes no sense to me and the only reason I see is to save time a money.
