Biggest DV Improvement

[JeremyW]

Which movie have you watched that showed the biggest Dolby Vision improvement over the same movie in HDR-10?

[Kris Deering]

I think there are some misunderstandings about the benefits of Dolby Vision vs HDR10.

The biggest pluses for Dolby Vision over HDR10 on a flat panel (especially one that is bright) is that it provides frame by frame metadata. If the display choses to use this, it will help any dynamic contrast system it has (this is definitely helpful for something like an edge lit LCD or anything that modulates intensity). The other main benefit is if the display choses to use Dolby's tone mapping algorithm (which is completely optional!) for titles that exceed the maximum output of the display (or that can't do the bottom end either). It also doesn't have issues with its metadata (many HDR10 titles have bad values for their static metadata which can cause issues with displays that actually take these numbers into account). DV is also 12 bit, so should be less susceptible to banding artifacts, but these should be very rare in 10 bit as well.

So ultimately, the differences have far more to do with the limitations and implementations of the display being used than the content itself. It makes it harder for the display to make bad decisions, IF they've taken full advantage of what Dolby can deliver.

can i disagree?

as i am about to re-view all of my Dolby Vision discs soon anyway, i will double-view in both HDR-10 and Dolby Vision

please note that i have two players (same exact model) with one in HDR-10 only and the other in Dolby Vision

additionally, i will certainly be acquiring more titles during the forthcoming holidays, so i will have many more titles in Dolby Vision to select from

happy holidays

Sure you can. But I'm with Kris, whose words have been carried with lots of weight around here and elsewhere for a long, long time now!

As Kris said, it mostly comes down to making up for display issues. However there are a few discs where the HDR 10 experience is borked in some way the Dolby Vision fixes. For example The Fog's compression issues are less noticeable in Dolby Vision, and I believe Saving Private Ryan has a chroma problem that is less visible in Dolby Vision.

These are few and far between though, from what I've gathered.

Valerian. Almost like watching two different movies.

Of course you can. While fixing some compression issues and tone mapping is technically correct, it’s a very small part of what Dolby Vision does. And no one really knows exactly what it does as it’s a closely guarded secret. But purely visually speaking, there are differences between virtually every HDR10/DV UHD ever made and some of those differences are drastic.

I never bother watching DV discs in HDR10 so I can't really say, but there's typically a vibrancy and sense of depth to the picture quality on a DV disc that goes beyond what I experience in HDR10.

[tcripe]

People say I’m crazy but I think The Last Jedi looks much better in DV when comparing it to the HDR-10 version

[miccheck]

Well, I am not an expert in all the HDR datas.
But I often see a really huge difference comparing DV to HDR10
And I spent hours comparing the same movies and at the same timelines
Some movies definitely had a way better DV than others.
What I noticed is most of the time the movie is a lot more washed out in regular HDR10, and you have way better skin tones and accurate colors in DV and DV look brighter without making the image washed out.
I think Dolby Vision is a must and they should release DV movies a lot more often, it often save a poor HDR10 disc. And it is definitely not just about brightness.

I would say you can get subtle improvements in overall picture quality with DV if done properly. I said subtle as you might have to freeze frame to discern quality differences from a reasonable viewing distance. Titles where DV made little to no difference to me were:

1. Venom
2. Jurassic World 2

If you want the best possible HDR PQ, dynamic metadata is the only way..

[miccheck]

The difference is crystal clear when done right.
Especially when HDR10 appear washed out compared to Dolby Vision.
Not all of them are that good, but there is a difference in at least most of them.
And it also depends on the scene, there were some scenes in Only The Brave where there were a really huge difference.
And Jumanji DV looks much much better even though the DV layer is very small.

If I would name each format, I would call HDR10 excellent, and Dolby Vision perfect.
When DV is done right, I literally cannot see how the picture can be better.
Like my girl said, it is just "Wow, wow , wow, wow, wow, wow, wow, wow, I have never seen something like that" yeah that many times wow

Now, please let me know few UHD titles where the difference is crystal clear in motion from a viewing distance of 7.5 ft from a 65 inch TV

What TV do you have? A "huge crystal clear difference" isn't really considered the norm at all, but if your TV really benefits from the dynamic metadata then that makes sense.

DV sucks.

It's just too bad that everything else sucks more.

Definitely. It sucks than HDR10--- and HDR20+++.

[bradnoyes]

Knowing gnj1958 I just figured he thought this thread was about VD.

[imsounoriginal]

Still never watched a Dolby Vision transfer at home, but it feels like I'm always reading complaints about DV doing something wrong.
