When someone claims that basic math and Apple's very own statement about what they require as sustained throughput is for getting 4K+HDR is wrong… then it's your fault. It's certainly not Spectrum's fault for making you think that 300Mibps isn't enough for a file that is probably around 2GiB per hour.

So my 300 Mbps PLAN where I only get 3 or 5 down quite often can stream at 4K? I thought you said it needed 15 Mbps?

Read what I said. 300 Mbps is my PLAN. I RARELY reach that speed. It drops to 3 Mbps A LOT and Spectrum says it's an issue on their end. My equipment is good enough for 700 Mbps speeds.

Do you really not understand that 15Mibps is 3 to 5x more than what you're now saying you get as a minimum sustained connection.

PS: Way to move those goalposts after saying you get 300Mibps and that it's still not enough.

Ok let me spell this out for you. On my Spectrum bill, it is 300 Mbps. In practice, it drops to 3 or 5 Mbps a lot. I RARELY GET 300 MBPS. Do you understand advertised vs actual speed? 300 Mbps is my plan. I never said I get sustained 300 Mbps actual usage.

This is why I want the videos for download. 1080p videos buffer a lot even.
 
If you actually ran the numbers you'd see how very wrong you are that 300Mibps isn't enough. Perhaps you need to get better equipment in your home or do some exploratory testing instead of blaming your ISP outright and claiming that both Apple are basic math are lying to you about 15Mibps sustained being a perfectly fine minimum for 4K+HDR.

15 Mibps = 57.2 Gibabytes per hour.

Speeds aren't guaranteed. There is always overhead for various reasons. You should know this.

Thank you. Is this some shocking fact that nobody knows? Spectrum needs to get off their ass and just fix our neighborhood. These constant patching up messed up cables is not doing anything. They have a van here every other day.
 
If that's true, then those movies are in terrible encoding quality.

1) That has nothing to do with bitrate. Name me a single Blu-ray title that would be higher than the theoretical throughput of 15Mibps if streamed. Blu-rays are 25 and 50GB, and 15Mibps is 52.7 GiB. If you run the numbers even ore you see that at even at 3GiB per hour from iTS you only need a sustained 6.81Mibps throughout for that node.

2) You've completely ignored the codec when focusing on bitrate, which is why HEVC allows for smaller files (i.e: few bits for a given second of compressed A/V) for a given quality over H.264.

That's why sustained in being used and Whiplash doesn't get when he says that my statement of "If you can sustain at least a 15Mibps you'll be fine to stream 4K+HDR content from the iTS" is false.
 
My Netflix streams 4K just fine, and I only need a 15 mbps connection for that. So not sure why anyone with over 100 would be struggling at all.
[doublepost=1505451694][/doublepost]Also, I'm sure the content is being rolled out over this week, so the "download" option should be coming - we don't even really have anywhere to play it on 4K yet, so I'm sure adding the catalog was the priority lol.

Because Spectrum is not bothering to fix our neighborhood. They just patch it up and come back in two days to do it again. I get down to 3 Mbps regularly. What is frustrating is that I get a CONSTANT 25 Mbps upload speed.

This sounds like a lawsuit waiting to happen. Only getting 1-2% of the speed you’re paying for is atrocious. Speeds are not guaranteed, however, a reasonable person thinks that means sometimes speeds will be a little slower(read as 60-75%) than what you pay for. 1% is unacceptable.

That sucks. I know my provider shapes my Netflix speeds during peak times (switches on at 7.00 pm and off at 11.00 pm) when traffic is high, so it limits it to 1080p. I can run a speed test and get 100+, and then run a Fast speed test and get 4-5 lol. But that's been a lot less lately as I think they're sorting out my neighbourhood. Hopefully Spectrum gets yours together!
 
So it seems like the 4K marker is just that, a marker. As of now it simply indicates the video files that intend to be upgraded. None of them are actually available for download at the moment. My copy of Star Trek is labeled 4K, but when I downloaded it to my iPhone, the downloaded file was the 720p version of the film.

It seems like the key to look out for is when the 4K file size is listed for the film. I think once that is displayed, it will be able to be downloaded at that quality. So all of you please keep a look out for a specific, listed, 4K file size (only up to 1080p is currently listed) and please report back here if you guys spot one!

Well, I just tried to download an "upgraded to 4K" movie on my iPad running the iOS 11 gold master. It only downloaded the 1080p version. My iOS 10 iPhone still only shows it as HD in the store.

1) That has nothing to do with bitrate. Name me a single Blu-ray title that would be higher than the theoretical throughput of 15Mibps if streamed. Blu-rays are 25 and 50GB, and 15Mibps is 52.7 GiB.

Good point, I did neglect to take in to consideration that HEVC will be good for 4K at 15 Mbps. I was assuming AVC, which is marginal at 4K at 15 Mbps. Certainly not something I would pay top dollar for. But HEVC should be sufficient. I was thinking that it was only half the bitrate of UHD Blu-ray discs. (Which go up to 36 Mbps HEVC.)

Yes and you know what's funny. Every time we contact them about this, they go on a 5 minute rant that "300 is only the upper limit, not guaranteed". You idiots, don't give me a 5 minute rant about the fine print on advertised speed when I am calling that I am only getting 1%!!
 
Will these be playable in 4K on Macs with retina screens? And if using a Kaby Lake Mac, will it use H.265 (HEVC) encoding? What about on a 10" iPad Pro?

I'm still not seeing anything show up in 4K in iTunes Mac (newest version).

I would like to know as well. 4K content will look VERY GOOD on my 2017 5K iMac.

That is interesting. Thanks!
 
I'm delighted with Apple pushing 4K, and with free upgrades no less. Apple's 4K H265 may finally be on par with Blu-ray 2K H264 in terms of quality.

But to be perfectly clear: If you haven't seen a 4K UHD disc up close on a decent, large-diagonal, 4K TV, you have no idea. The visual quality is much better than most movie theaters (all but one screen near me use 2K projectors), and will very likely be better than anything streaming over the Internet that you didn't pirate, Apple/iTunes 4K included.

In isolation, 4K UHD disc pricing (~$25/disc) is absurd. When compared with $18/person for an "IMAX" (quotes) movie ticket (the only way I can see 4K locally in a theater), let's just say we get a better overall movie experience on our couch. Home theater has well surpassed movie theaters. Let me know when theaters get laser projection and burly dudes with stun guns for anyone that turns on their phone during the movie.
 
I can stream 4K with my 20mbps DSL service, but my point is that nobody can stream Apple's 4K at this time as no one has a Apple TV 4K yet.
Theoretically, shouldn't they be playable in 4K on retina Macs with Kaby Lake chips (hardware decoding)?

Yeah, UHD content is ridiculously expensive (only speaking for Australia, but I'm sure it's the same worldwide).

Standard new release, $50. https://www.jbhifi.com.au/movies-tv-shows/movies-tv-shows-on-sale/horror/it-2017/499449/

Special edition, $100. https://www.jbhifi.com.au/movies-tv...e-third-kind-40th-anniversary-edition/498687/

And then of course you need to buy the players, which are around $400-500 here.

I do want Planet Earth 2 UHD more than anything, though. Lol.
 
So how does 4K content from iTunes compare to 1080p Blu-ray?

There are many factors involved here, even down to the display size and type, and viewer's position to it that affect that result, and we yet don't know what HEVC profile and other settings will be used for iTS 4K content. It may come down to determining who has the most artifacts, like banding when there's a lot of black on screen.

Audio is another consideration.

How could you tell it was 720p? Is there some indication in the TV app? The visual difference would probably be unnoticeable on a screen that small.
