iPad Pro HDR questions...

[bmac4]

Seriously, I completely understand what you're talking about. We are talking about HDR video streams. C'mon. Can you play Mad Max Fury Road in HDR on your iPad? No, you can't. That's what I'm trying to achieve here.

Honestly curious about this, but how will we know when the HDR video works correctly? If I select a tv show like the Grand Tour from Amazon, it will play and it's HDR, but what let's us know it's not playing in HDR?

Oh and sorry your thread has been destroyed by the user that has no clue what the question is about. I completely understand what you are asking.

It will be able to play the video, but the relatively low contrast ratio on iPads won't really show the full potential of the format.

The frame rate and resolution has nothing to do with HDR. HDR means,for proffessionals,only High Dynamic Range. That only has to do with Color depth and contrast. You're talking about video frame rate and resolution,that's a totally different matter. Please use proper terminology,and yes,I know what I'm talking about,been using both still and movie cameras on almost daily basis since late 1970s,so I guess I have some experience of most kinds of visual media. The problem with YouTube videos is not HDR or not,it's frame rate and resolution.

Right, but what lets us know if it playing in HDR or not?

No you have no clue what you are talking about. This has nothing to do with frame rates, and he said nothing about frame rates. Seriously get a clue. We all know what HDR is. It's going to make the picture colors pop more, and over all look better. You just need to stop, or admit you have been answering the wrong question all along. You may be right about what you are saying, but it has nothing to do with this thread.

This is like asking about how the supercharger in a model of car works then someone comes in saying they’ve been using turbo on their cars for decades. Please stop.

I'm guessing it would be similar to how it does when it's on my tv. It will display "Dolby Vision" on the screen, or on the device casting.

It's ok, I'm ignoring it...

It will be able to play the video, but the relatively low contrast ratio on iPads won't really show the full potential of the format.

I'm interested in how it'll look compared to the same content in SDR. If it's an improvement, then I'll bite; per se. hehe

Didn't apple say they Supprt hdr via dithering? Or was that the iMacs? That would suggest they're still 8 bit screens and they're simulating 10 bit colourlike some budget 4k/HDR TVs

I don't remember that being said at the wwdc regarding the iPad.. I'll watch again and see if I missed it.

Jut checked - it was the iMacs (10 bit dithering)

Read my posts please,I clearly explained what HDR is. When I shoot my own HDR photos/ videos,I get full HDR Color depth on my iPad Air 2.

I'm sorry to say this, but what you clearly explained has nothing to do with what the OP is talking about. What you're talking about is HDR in photography, which is taking the image by making several images of the same scene at various shutter speeds. What the OP is talking about is HDR Video (has nothing to do with HDR in photography even though the name is the same). HDR10, HDR10+, Dolby Vision, HLG - all different standards of HDR video.

Basically it's a video with very high brights and low darks, with increased range and detail between the two, wide-color space, etc. It's also a big deal in gaming and, frankly, looks incredible. It usually comes with a 4K TV, although technically, it has nothing to do with resolution.

Netflix, Amazon, etc support HDR videos for certain shows (yes, the video or a game must be mastered for HDR for it to work). Consoles support it also - PS4, PS4 Pro, Xbox One S, Xbox One X and it started coming to PC gaming too. You can imagine that if iOS developers start creating games for it, they will look spectacular.

I would also love it if Netflix starts supporting it on their iOS app. Since the new Apple TV is rumored to support HDR for HDR TVs, I can imagine it will, if not sooner, than at least when the new Apple TV comes out. However, there are many questions - does iPad support the widely accepted HDR10, or something else? Also, for YouTube to work, Google must enable it, and they still didn't do it even on their own Android TV 7 (I have a Sony TV with it and HDR doesn't work in Google's own YouTube app, so I'm not so sure if we'll see it on the iPad soon).

Very well said. Thanks for the informative response.

This is Apple, and Apple is good at making deals and getting support from others. Also, when you think about it, Apple put HDR on the iPad but didn't talk much about it - that must mean they are waiting for something to talk more, and that something is the iPhone. You can sometimes deduce some of their plans when you look at the bigger picture. I expect the next iPhone to have HDR and the next Apple TV to have HDR support for TVs and then they will announce content, games, apps supporting it. And then they would be like: "Oh, remember that the iPad Pros support HDR?". I'm guessing they will talk about HDR much more on the next event.

Netflix announced they are planning "mobile HDR" and I bet we get to enjoy HDR content on our iPads and iPhones and Apple TVs by the end of the year:

They are such a tease lol.

Obviously,you still don't understand. Ever since the 1980s,most color screens had capability to show HDR,including first generations of iOS devices,what you're asking for is something called 4K, which is extra high resolution. HDR mostly affects color and contrast,definitely not resolution. So,what you're looking for is 4K,not HDR.

Stefan you clearly don't understand what op is talking about and your are confusing other people. From Ops first message i already understood what he is asking. HE IS NOT ASKING ABOUT 4K get it to your head.

Just to clear up another misconception in this thread: HDR per se has nothing to do with color space. HDR is only about luminance levels, that is, the possible range of light output from most dark to most bright. You can in principle have sRGB color space with HDR, or even monochrome grayscale with HDR.

The UHD standards have four aspects, all of which are orthogonal to each other:

• 4K (pixel resolution)
• WCG = wide color gamut (color space), more specifically P3 and Rec. 2020
• HDR (brightness range)
• HFR (frame rate), currently up to 120 Hz

Both WCG and HDR are supported by a higher bit depth (10 bits currently), which is necessary to avoid banding artifacts with WCG/HDR.

The hardware of the new iPad Pro models now support P3 color space, HDR with 600 nits maximum brightness (with 10 bit dithering I suspect) and 120 Hz frame rate. (But no 4K resolution, obviously.) What's still missing (or in need of clarification) is software support, both on the iOS level and by relevant apps.

Completely true, but generally speaking, when people talk about HDR, they are talking about the experience more than technical definitions and that includes wide-color gamut and 10-bit depth alongside luminance.

I tried to explain this to him in a different thread and he really doesn't at all get it and repeats again and again that he's been shooting photos that way for years. I got no answer when I tried to ask how he's grading video shot on an iPhone to HDR10.

I'm not even going to bother ranting here. klasma did it perfectly already.

I will step in on this one, as someone who does photography too. They are different, but related. Take a scene or setting that has a wide dynamic range. Say 20 stops worth of range.

In photography, you take multiple exposures so you capture the whole range, combine them, and then compress the whole thing into the dynamic range of your display. The compression is to fit it in the 6 stops that a calibrated monitor can display.

When talking about video, it's two things. First, some video metadata that allows you to specify the range of the video data and how the luminance values track. So this lets you have a video file that represents a scene with those 20 stops of dynamic range. Second is display tech and software to make sense of the metadata so that the display can be calibrated to display a much larger range than the standard 6 stops. They can't get to the point where they can show 20 stops yet, but that is what folks like Dolby want to achieve.

Im just wondering does the ipad pro 10.5 support HDR10 (the latest and most up-to-date HDR with additional color gamuts) like the galaxy tab s3. Also, can the ipad pro achieve 680 nits of brightness when watching HDR movies like the galaxy tab s3. It just seems like Apple is ignoring the HDR capabilities of the latest ipad pro.

If you want true HDR,buy yourself a good DSLR with HDR photography in it,and learn to use it. Let the camera do the HDR work,and you will then get great photographs,with HDR added,as JPEG files that would show well on any iPad with retina screen. The software used for HDR in most cellphone cameras,are just a function that change contrast,hue and saturation,not true HDR. A HDR enabled camera,do usually take 3 pictures,underexposed,normal exposure,and overexposed,then all three are put together as layers in the camera,and saved as JPEG file together with the normally exposed picture. Then,after importing photos to iPad or computer,it's up to you to choose which one to keep,or keep both.

i was referring to HDR for movie watching.......not the camera
