iTunes HD videos low bitrate, include iPod-ready versions

post #1 of 97
Thread Starter 
Those expecting Blu-ray level video from Apple's new HD TV shows may be significantly disappointed -- though buyers will find a surprise in the form of a smaller version for their iPhones and iPods.

While Apple's announcement on Tuesday that it would start offering TV in 720p high-definition directly through iTunes has been hailed as a significant move towards better-quality video through the company's online store, Gizmodo today reminded would-be viewers not to expect a direct replacement for Blu-ray discs or even some purely digital formats.

A standard 720p file downloaded either through iTunes or an Apple TV consumes about 4Mbps of data, or just a tenth the total bit transfer rate of the optical format and a fifth of the nearly 20Mbps for over-the-air HDTV; even Xbox Video Marketplace video affords more, at 6.8Mbps. Some of this shrink in file size can be attributed to features left out of Apple's encoding, such as the 1080p resolution or 7.1-channel surround audio, but much of it is attributed to compression that can degrade the final picture quality significantly from the reference image.

Such reductions can often lead to smearing in videos, particularly in fast-moving scenes where the bandwidth allowed to the video isn't enough to keep up with the changes necessary for the picture.

The bitrate isn't an automatic gauge of image quality, however. As discussed in AppleInsider's Apple TV quality comparisons, video format choices and other factors can actually result in supposedly higher-bitrate cable TV sources faring worse than Apple's H.264 videos, which are more efficient at compressing data than the MPEG-2 format used by some TV providers and older Blu-ray titles.

Apple also isn't seen as having much choice in the matter due to the nature of Internet technology. An HD TV show on iTunes can be nearly three times the size of its standard-definition equivalent and downloads slowly enough on most American connections that it may be difficult to start watching in real-time, with an example show taking 40 minutes -- or nearly its full duration -- to finish downloading. Higher-quality video would both be impractical for some connections and quickly fill up hard drives.

As a compromise, Apple is known to be offering portability, something that most Blu-ray or cable video-on-demand services can't offer themselves. Ars Technica notes that Apple has quietly made sure that all HD downloads from iTunes also include an SD version as part of the purchase.

The lower resolution chews more disk space but also guarantees that buyers will have a version of their TV show choice already formatted for iPhones and video-capable iPods; none of these currently have the performance, the displays, or the capacity to practically support HD playback.

Bundling a second copy of a title also puts Apple slightly ahead of Blu-ray in HD TV bundles: while a handful of Blu-ray and DVD movies now offer an iTunes Digital Copy that achieves a similar effect to Apple's new venture, most TV series collections still largely include just the original video and can be difficult or impossible to copy.

Not enough people have the bandwidth yet to justify full 1080P. Not even the FIOS people have that kind of bandwidth to burn.

Some TV providers? I am under the impression that almost all of the US providers are using MPEG-2 still. I'm also under the impression that OTA HDTV is also MPEG-2.

For comparison, my local cable provider uses Scientific Atlanta boxes, uses MPEG-2, and offers between 16-19Mbps for the average HD channel.

DirecTV uses MPEG-4; dunno about the bitrate.

This is why God invented Blu-Ray

Internet-based High Definition content is a joke with today's bandwidth. I downloaded the free pilot episode of Monk last night; despite taking three times longer to download and sync with my Apple TV than it took to watch, the quality was below that of an upconverted standard definition DVD.

What res are HD shows? My old SD episodes of Battlestar Galactica were 640x360 (not x480 because they are widescreen). I downloaded an episode today and it was 853x480, which looked good and exceeds DVD, but I would have thought you'd need at least 720 to call it HD. Did I get the HD version, or are they just using higher quality for SD now?

And where would the second version show up, if I got both HD and SD? I only see the one listed in my Library.

TIA

I saw Apple had some Battlestar Galactica episodes in their HD section that weren't actually HD; that is what you got if it's resolution isn't 1280x720. 853x480 is the standard definition size for 16:9 anamorphic material.

Notice how this entire controversy is based on the lower bit rate and that they "attribute" to this and that? i.e. - they have no real idea of why the bit rate is lower and no hard information on whether the picture quality is lessened because of it. What matters is how it looks to the end user. If no noticeable pixelation occurs and the signal is comparable side by side to a higher bit-rate HD, what does it matter if Apple puts the signal together a different way?

Everyone who knows anything about the tech press knows that Gizmodo is just a bunch of disagreeable twenty-something tards that find fault with everything they look at and generate huge controversies out of virtually nothing. They have been guilty over and over again of "crying wolf" when it's simply not justified. Then the apologise later and laugh all the way to the bank.

Their "analysis" is probably worthless and certainly not worth considering until someone else who actually knows what they are talking about chimes in with similar results. The day I trust someone who reviews tech products based on how it makes them want to jerk off (yes, they have done this) is the day I give up on tech journalism in general.

I would love to comment on the quality of the Hd. downloads but unfortunately I can't. Itunes downloads both the Hd. version and the standard version of the show. Unfortunately itunes can not find the Hd version.

\ Are you for real?

The difference in quality is very, very apparent. GIzmodo is not blowing things out of proportion. An upconverted standard definition DVD looks better than what Apple passes off has HD. Gizmodo clearly state that there is noticeable pixelation, and even back their claims with photo proof.

Maybe it might come close to cable TV, but as a point of reference after some initial missteps, my HD from Comcast has actually vastly improved (ditching their crap cable box that I had replaced 3 times for a Tivo HD has also helped my satisfaction).

If iTunes had been offering HD TV a few months ago, it (and an AppleTV) may have been a potential cable replacement. But at $3 an episode, keeping cable could quickly become a cheaper alternative. And comparing prices, it's not much cheaper buying a season from iTunes than it is to get it on Blu-Ray (example, Heroes Season 1 is $64.95 from iTunes or $69.99 for Blu-Ray from Amazon.com).

I downloaded and watched a couple of episodes of Californication in HD yesterday. (btw: ).

I didn't have *any* problem with the quality of the image in regards to the bitrate. There were no noticeable degradations to the image in fast-moving scenes as this article warns of. It's true that it doesn't have the freaky sharp look of Blue-Ray played on a top-of-the-line HD television, but it certainly isn't "smeared" or flawed in any other noticeable way.

Watching on my 30" Apple Cinema Display, the real problem is the resolution of the image is so small that to fill the screen I have to watch it at double size. Obviously this makes the image considerably less crisp to the naked eye. The good news is that even at that magnification the image looks very good, it's very watchable (unlike the SD downloads from the iTunes Store, which look terrible when blown up to full screen on the 30"). Any softness comes across as more cinematic than as digital degradation.

In the end, with the current format using 1 GB per 30 minutes of television, I would be less likely, not more likely, to purchase shows if they took up exponentially more hard drive space. Even if I bought a 1 TB hard drive just for my iTunes library I'd be concerned about running out of space if the HD downloads were 5 to 10 times as large.

The iPod and iPhone can't play HD content so bundling an SD copy with it is a good practice. While buying an HD copy means you intend to view it on your AppleTV or in iTunes, people do watch content multiple times or the may need or want to transfer the content to their iDevice after watching it part way through in HD. The benefit here is that Apple thought ahead for once on this front.

From what I've seen some iTunes HD downloads exhibit more artifacting problems than others. The blame for this lies sqaurely with our internet service providers. Apple is working within real world bandwidth limitations.

Yes Blu-ray clearly offers a better picture than any internet download is capable at this point. That is a temporary difference as bandwidth speeds increase download quality will increase.

This depends on how much television you watch. My cable bill is around $120 a month, around $720 for an entire television season. A season for a couple of shows would be far cheaper. This would be a great deal if iTunes offered lower cost television rentals.

That doesn't matter as no iPod is capable of playing HD.

The point of the SD version is to have the ability to watch your purchase on a portable device that cannot play HD.

Am I missing something here- did anybody actually really expect these HD downloads to rival Blu-ray? The good thing here is that we are finally getting a download worth watching on our HDTVs - that is convenient and you can finally own. And 2 versions at that! Everybody needs a realiity check and just get a grip- this is fantastic. No physical media to clog up shelf space- excellent. And we're talking TV shows here not cinematic epics like The Lord of the Rings.

No it won't. If downloads of lower quality are successful, why would they increase the quality? Cable and satellite providers have been lowering the quality of their broadcasts for years to cram more channels into their bandwidth and people eat up the "digital quality" crap (my cell phone shoots "digital quality"). It is in EVERY media provider's best interests to provide you with the LEAST quality that MOST PEOPLE are willing to tolerate. That's just good business. Any more and they're wasting money.

I work in television on HD sports programming. A two-hour show can approach 1TB in size and it is amazing to watch on a $20,000 HD reference monitor, Apple compresses that down to 4GB. What you see when you watch material on one of our "HD" networks is a joke. What you are downloading from iTunes isn't HD anything. It's the same size as an HD frame, but it's compressed all to hell.

It's still better than what they offered before in SD only- so who cares?

Unless of course they are watching Apple's content on a 1080i TV with a crappy upconverter. Standard def DVDs look better on my 1080p Panasonic than HD content looks on some of my friend's low-end HD TV's. And it was vastly superior than Comcast's HD content before the finally got their head's out of their arse and addressed their compression problems. How they are connecting their Mac or AppleTV to their TV and where the upconversion is taking place can make a huge difference.

I'm not saying Apple's HD is of superior quality, I haven't tried it yet (letting all the rest of you complete your beta testing of iTunes 8 before I install it ), but there are a lot of variables that need to be taken into consideration. But in general, I've found that Apple does a very good job of maximizing image quality within the bandwidth limitations.

Precisely my point. The quality will not improve if the current level of compression is acceptable. Those who say "it'll get better" are just wrong.

Digital downloads were successful when Apple was pushing 320x240 music videos. YouTube is successful. SDTV was successful. DVD was successful. We always want more and better and companies will give the customer what they want if it means getting their business, but if there is no competition in your market then there is no reason for them to improve.

You are saying that this is the best quality iTS will even have for video? If BR gets the traction Apple will have to respond. If Amazon or MS' video stores offer better quality to steal Apple's iTS customers Apple will respond in kind.


News as of today shows Vudu doing that exact thing. I highly doubt the bitrate will match BR, but for the convenience it doesn't have to, but one thing is for certain it'll be better than iTS and if gains traction Apple will up their quality.

Of course all technology improves eventually so I don't think that's what he means. And Apple will not be able to compete with BR- because of all the extras BR offers- so forget that. BTW Blu- ray should get a lot of traction this holiday when the players go below $300.

Apple really, REALLY needs to start looking at digital downloads direct to iPod Touch/iPhone from a kiosk. The whole bandwidth thing is an intractable problem for ALL providers of entertainment over "underperforming" lines. This is a problem that no one has been able to solve even with better compression.

I don't understand how this helps. Bandwidth is fine for SD downloads, HD is the problem.

Its all pretty relative. The further you sit away from your HD television. The less you will even notice more detail in the image.

I think Blu-ray has 5 years at the most. Compression and bandwidth will both improve and will get to a point where the image is good enough for the convenience of downloading from your couch without depending on physical media.

This is true, and something a lot of people don't realize. But if you're sitting too far away to be able to tell that Apple's HD looks worse than an upconverted DVD, what are you paying the extra dollar for? Moreso, what'd you buy that fancy 1080p HDTV for

Is Apple going to come to my house and safely archive 2TB worth of movie and television purchases for me, as well? I think the instant gratification of downloads is offset by the time and money it takes to safeguard all of that diskless data. It'd be awfully upsetting to lose hundreds or even thousands of dollars worth of movies and tv shows. If Apple kept track of your purchases and allowed you to redownload them in the event of data loss, this would of course become a non-issue.

There is an evidence to support Apple letting people re-download all lost media they've purchase at iTS. As for safeguarding it, digital media is more like an airplane disaster and optical media like a car wreck; optical media gets destroyed accidentally more often than digital and may only suffer a scratch, but when digital gets destroyed it's usually completely effaced. And we know people are more scared to fly than to ride in a car, yet they are more likely to die in a car crash. (even here we can't escape an analogy with a car)

As for your archiving, people have the same reservations about all the VHS media they accumulated. Same thing with cassette to CD. You can still keep your current physical libraries and have a digital one too. Oh, but make sure you properly backup your content

Speaking of, Apple needs their own RAIDed home server or RAIDed Time Capsule. Windows Home Server is pretty damn nice for an implementation of Windows. The fan on my HP Home Server is louder than I'd like, but beyond that I have no complaints.

You say that as if its absolute fact. From what I've seen their can be some higher degree of artifacts and aliasing in iTunes downloads but not all the time.

You are also able to burn iTunes media files to DVD if that makes you feel more secure.

Maybe "get info"? I see two downloads, though I would think that Apple would stack them or hide one in a way that it doesn't cause confusion where someone would delete a duplicate.

Is it really that size? Does it say that with "get info"? Apple doesn't seem to show the res numbers on the store. It doesn't make sense to use that res and give it 3x the data rate.

Other than a notebook computer, I don't know of any portable device that can play an HD video.

I think it's a fine bonus, because of the above fact. Not only that, even if iPhone can play it, I don't want a file on it that's so much larger than it really needs to be that I'm storing 1+ GB of data on the device that would make no absolutely difference in how good it looks on the portable display. It's nice to have one purchase that covers a broad range of devices rather than one purchase that covers just a couple devices.

It's too bad that there is no consumer-accessible high quality wavelet codec, this would be unnecessary. To copy it to an iPod, all that would need to be would be to just copy certain chunks of the file.

With Apple's introduction of TV series in HD, their HD catalog might be getting close enough in title count with Blu-Ray, and there's probably not so much authoring and up-front mastering cost as with Blu-Ray. Then there's the convenience factor, getting an episode shortly after it airs vs. waiting 6+ months for the BR set. So there's a chance that Apple can actually get some traction if they can maintain a certain level of quality, even if it's not going to be the same as BR.

If iTS's 128Kbps audio with DRM can trounce CDs with all the extras that come with it because of its overwhelming convenience, then I think that Apple and other online distributors have an excellent chance. Especially since DRM is now a part of both video formats.

The studies I've seen basically resulted in
1) BluRay (or HDDVD) are the best
2) AppleTV HD next best
3) HD mpeg4 next (on cable or satellite)
4) HD mpeg2 (via FTA or cable)
5) DVD
6) AppleTV SD
etc etc
That would agree with my experience too. I haven't used MS Xbox.

Also it's interesting that there are now proponents of a new compression scheme which deliberately downgrades the detail of fast moving scenes - to avoid pixelation and actually decrease the bandwidth of those scenes (in contrast to the regular increase in bandwidth). They focus their efforts on slow scenes where the viewer can actually see the quality.
.... This type of compression would be very bad by Gizmodo's tests (and the studies I've read) since they take fast moving scenes and pause them, analysing the quality frame by frame.

I guess what I'm saying is, I'd like to see viewer reactions to various qualities. I know for me that regardless of compression 720p looks no different than 1080p - and 4Mbps 720p will be better quality than 6Mbps 1080p.

You are also able to burn iTunes media files to DVD if that makes you feel more secure.

Unless I'm mistaken, the only files you have been able to burn to physical media from iTunes are music files. Movies and TV shows have never been able to be burned to DVD, and I still haven't been able to find a workaround for it, either (though not for lack of trying )

It can be burned to DVD as a data file. It would not be burned as DVD-Video. I think it defeats the point of digital media, to not have to manage a bunch of discs. I'm a lot better at managing pressed DVDs than I am burned discs.

And we know people are more scared to fly than to ride in a car, yet they are more likely to die in a car crash. (even here we can't escape an analogy with a car)

One problem I've had with my iTunes library is that occasionally files turn up missing, thankfully it was usually just a disposable podcast or a free sample download. A backup does not help me as a backup would copy the state of the existing library before I am aware that files are missing. I have no good way of maintaining an archive, too many files would be spread over too many discs.
