MPEG releases H.265 draft, promises twice the video quality by 2013

post #1 of 92
Thread Starter 
The Motion Pictures Expert Group has issued a new video standards draft that promises to deliver twice the video quality at the same size, or alternatively, identical video quality at half the data rate as today's MPEG-4 H.264 standard.

The new H.265 draft specifically addresses mobile devices and networks overloaded with video. Products using the new H.265 video compression standard could begin to launch as early as next year.

Apple is likely to quickly adopt support for the new H.265 specification, just as it has rapidly rolled out support for new features of H.264, including support for expanded H.264 profiles in the new third generation Apple TV and the New iPad.

MPEG, formed by the International Standards Organization in 1988, first developed a joint video compression format in 1993 intended for Video CD. Its video codec, H.261, was used to deliver multimedia video clips. The audio portion of that standard, MPEG-1 Audio Layer III (also known as MP3) revolutionized the portability of music by allowing users to rip CDs to files that could be compressed enough to be used in mobile devices with limited storage.

Apple promotes MPEG at the expense of proprietary codecs

Apple backed MP3 with the iPod in 2001 at a time when Microsoft and Sony were working to entrench their own proprietary standards with strong DRM (Windows Media and ATRAC, respectively).

MPEG released the MPEG-2 standard in 1994, which enabled high quality DVD and efficient digital TV transmissions. MPEG-2 incorporated the initial H.261 video compression standard as well as a more efficient H.262 and, later, the H.263 ASP codec implemented by DivX and Xvid, popular formats used for video file sharing. Work on an MPEG-3 standard aimed at HDTV was abandoned and folded into the MPEG-2 portfolio.

MPEG-4, initiated in 1998 and released in 2003, merged the television and video industry's expertise with work pioneered by Apple's QuickTime on desktop computers, resulting in a video format that incorporated Apple's QuickTime container format. This helped to simplify video editing tasks, even as Apple began adopting advanced bidirectional compression technologies in QuickTime that had been contributed to the MPEG-4 pool by the rest of the industry.



MPEG-4 carried forward H.263, which Apple hadn't ever widely used, while also introducing H.264, which enabled a doubling of video quality at the same size as the earlier H.263 codec.

Before MPEG-4, Apple had previously used proprietary video codecs from Sorenson in QuickTime, but rapidly began adopting MPEG standards as the pooled efforts of every major company with video expertise began to quickly outpace the development of alternatives.

Apple helped to popularize MPEG-4's AAC (Advanced Audio Codec) format as a more efficient replacement for MP3 in iTunes, then brought MPEG-4's H.264 video compression into the desktop computing mainstream as the default video codec in QuickTime. It is now essentially the only video standard supported by the iPhone and other iOS devices, and H.264 is deeply integrated into the architecture of QuickTime.

While MPEG itself usually refers to its MPEG-4 audio and video standards as AAC and AVC, Steve Jobs introduced the new video standard to the world as H.264, and Apple continued to refer to it by its ITU numerical designation. MPEG is now referring to its newest H.265 standard as "HEVC" (High Efficiency Video Coding).

The war on MPEG-4 H.264

In 2009, a consortium of web browser vendors led by Mozilla and Opera began to oppose MPEG's H.264 for use on the web to deliver video after Apple, Nokia and Microsoft recommended it as an alternative to plugin based video delivery (typically Adobe Flash) in the emerging HTML5 specification.

Mozilla recommended the open source Ogg Theora instead, despite the format's inability to play back efficiently on mobile devices (which all have H.264 hardware compression, but rarely support anything else) and its much lower technical sophistication compared to H.264.

Google joined the fight in in 2010 after acquiring the proprietary VP8 codec and releasing it as WebM, a free, open alternative to H.264, albeit without any certification of protection from future patent claims.

Google insisted that the patent licensing required by H.264 made it incompatible with the open nature of the web, but the WebM alternative it offered was immediately accused of infringing the patents H.264 incorporates.

Google subsequently acquired Motorola Mobility, gaining ownership of several patents essential to H.264. It has used these patents to seek import injunctions and demand billions in licensing royalties from Microsoft and Apple as leverage against patent infringement claims targeting Android.

I'm not one for modern or mainstream music, but "let's get it started, hot, let's get it started, in here."

 

Who else thinks iTunes might support this come the September/October update? Who else thinks Apple will start converting all of their iTunes video content to HEVC to be completed by the end of next year?
 

And most importantly, who has a guess for when HandBrake will support this so that I can get my terabyte of content shaved down?

Apple's not gonna start converting shit until there's Universal hardware support, hell even the latest GPUs and CPUs don't support H.265, and do you know how much processing it would take on regular hardware using a software based decoder? you'd get like 2 frames a second on a good day.

 

I don't know about you, but it takes about 3 days for my computer to compress a BD rip to an 8-12gb rip... Now imagine all the new algorithms and complexity aded to H.265 to make it the same quality at half the bit rate...

On a high-end PC/Mac you could decode H.265. The bitch is encoding. Also the talk about bandwidth savings is currently a crock. You have to have hardware capable of doing a very high quality encode to see those kinds of gains. Most of the first to market solutions will not yield as much savings as you can trade off bandwith savings to lower the demands on your encoding. Since many solutions will either be general CPU or DSP based, people will take that trade off.

Can't wait for h.265 since it will be better, but the hardware is a probably a couple years out to do this in mobile devices. I can see something like a 16-core have a go at it with half the cores though.

Split the difference please! Videos encoded a bit smaller yet also a bit higher-quality would be great. My awful AT&T DSL is just SLIGHTLY too slow for much of the video on the web these days.

HEVC gives smaller file sizes at higher bitrates. No need to split it when you get both!

post #9 of 92

YAY! Another codec we have to deal with in post production.  The size reduction is welcome, the extreme processing overhead is not.  

 

Since is only draft at this point won't it be quite some time before we see this in use?  Certainly hardware acceleration is way far off.

post #10 of 92
If Google would have it their way, investments in technological advancements like this would probably not be possible, since everyone was still using an inferior h.264 knockoff codec because it's supposedly 'more open and free' :-/

I can't wait until this becomes mainstream, with hardware codec support. A good Blu-Ray encode is around 8-10 GB right now, and while I'm not particularly bothered by the file size, the quality of such an encode is decidedly worse than a Blu-Ray disc. Same bitrate double the quality please :-)

Who thinks they will go for same quality at lower size because the ignorant studios won't let them do true blu-ray quality with all the audio etc as it would hurt disc sales

But that is exactly what we need. Along with global releases especially of tv shows (within the month of first OTA on shows and same day if not before disc release on movies), everything in the highest quality possible. Get Extras to work on iOS. Drop everything down to the SD only price but for all size options etc. And all 'in the cloud' with control over immediate download or streaming on all devices. And on tv shows get the nets to add those funds to the ratings for deciding what stays and goes. Do that and torrent usage would go down a great deal since it destroys all the reasons casual users give to justify why they do it.

Imagine the uproar when torrents start moving to HEVC from MP4. They whined like newborns when AVI was finally dropped, and that was completely worthless. lol.gif

That's encoding, not decoding, which always takes more resources. And who knows what decoding would take or what Apple has in the pipeline. They could be working on a new Apple TV set box which could handle this that would be out for the holidays. They would likely slowly bring this into the game starting with big name releases or just one or two studios, perhaps as a Super1080 option that would slowly replaced the current 1080 on back titles. Perhaps this would have the power to make digital 3D releases possible and they might start with that. Say with all the Disney/Pixar titles that a being converted. I would pay the current $19.99 digital price if it came with SD, 720, 1080 and 10803D especially if it had several language and subtitle tracks, the disc features etc,

Right now iTunes is giving us 1080p that is about the quarter of the bitrate as a BluRay with way less quality on the audio. If they could do true BluRay with only like a 10% size increase many would go or that. Especially if they kept the current 1080 option in play. Hell they could probably get the current 720 down small enough that the SD option could be phased out

The casual folks really don't care about such things, especially if they we finally motived to go to legal sources.

The diehards will gripe about everything.

I have noticed video issues a lot lately even though I have really fast connections. It seems quite often with streaming video, it doesn't cache. It just buffers a little and starts playing, but as soon as it plays it apparently flushes the cache behind the play head. Somethings if it stalls and if you try to back up the progress bar, it will start buffering again and often never fully recovers to playing smoothly.

 

I remember not that long ago that video would stream, but once the file was downloaded it stayed in the cache for days so if you wanted to watch it again it started immediately and played smoothly all the way through spooling directly from the hard disk. I don't think it works like that anymore.

 

I don't know if it is HTML5, H.264 or perhaps a setting in Safari that is causing the frequent flakiness of web video streaming. Mostly Youtube video plays smoothly enough so it may just be video from servers that can't deliver enough throughput, but it is frustrating when you have 10 Mb (home) and 100 Mb (office) and you still get stalled or stuttering video way too often.

I don't think you meant to say that.  File sizes are determined by bitrate (multiplied by time).  I think you meant to say that HEVC gives higher quality at lower bitrates.  There is a split decision to be made.  You could get half the bitrate at the same quality, or improve the quality and get less of an improvement on the bitrate.

 

Or you could scale quality based on connection, potentially even user selectable.  For example, streaming over 3G/4G where one may be charged per GB, one might want to go with a forced lower quality.  At home, where one may have unlimited data (or never hit their cap), one might go with dynamic scaling and get the best quality their connection is capable of.

Oh, it's more, but much of it's not mine and all that would be on discs still. All I want is for the Apple TV to support a hard drive with a standard iTunes Library file structure when just the hard drive (not iTunes the application, not a computer ON and iTunes RUNNING on it) is connected to an AirPort (it wouldn't even have to be third party router support!) on the same network. 

 

Once that happens, I buy three Apple TVs on day one and two 4TB hard drives on day two. Rip all my family's discs, convert to HEVC files, get them looking gorgeous in iTunes with subtitles, metadata, chapters, and artwork, and then clone the first drive and plop it on the network standalone.

 

That's all I want, Apple. NAiTL (Network Attached iTunes Libraries).

Indeed as we get these staggeringly high download speeds it all to often reveals the limitations of the other end. On the other hand I started watching the NBC Live Olympics on 75 Mbs download at home and went on vacation to a place with 5 Mbs and there was zero difference in the HD quality which truly shocked me.

That's kind of my set up, I have a SATA dock on FW 800 to a MBP and dozens of 1 and 2 TB bare drives with HD videos. All the videos are aliased in iTunes and available to the home network as long as the correct drive is docked. It works like a charm. ... But I hear you on the NOT tying up a Mac, that would be sweet.

I haven't quite figured it out, nor have I had the time to research it but for example there are sites that if you plug in the URL of a movie or you sort through the view source to discover the actual movie src, you can download the complete movie is seconds, way faster than realtime and once you have it on your drive it plays flawlessly however trying to just let it stream as a normal person would do it stutters and drops frames. I just went to Apple and watched the main home page video and it dropped frames several times and the lip sync was off a bit at times as well. I'm on an unthrottled (no QoS) 100 Mb line right now too.

 

Edit: and I forgot to mention I'm on a 8 core MP with 16 gig of ram and nothing going on in the background..

In which case it sounds like you have a problem streaming your end for some reason. Can you boot to a different drive with a nice clean install and see if it streams any better on the same Mac?

I wonder if the following might be an interim solution:

 

http://www.patentlyapple.com/patently-apple/2012/08/new-apple-patents-relate-to-sim-cards-radio-transparent-materials-video-editing-more.html#more

 

Towards the end of this article there is a reference to two additional patents:

 

 

Quote:

Lastly, for those interested in patent applications relating to video coding, see patents 20120195376 and 20120195372.

 

http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220120195376%22.PGNR.&OS=DN/20120195376&RS=DN/20120195376

 

It is a little hard to follow, but it seems to say that [much of the] compression is achieved by dropping intermediate frames and replacing them with hints -- the hints are used to regenerate the missing frames at the other end.  I think this patent is directed at existing hardware.
 
As an aside, I experimented with a similar technique using Apple's "Optical Flow" feature of FCP X.  
  • converted a video to frames (image sequence) using QuickTime 7
  • dropped some of the frames -- for instance 3 or 4 out of  5
  • converted the resulting frames back to a video using QuickTime 7
  • used Optical Flow to smooth the video (generate missing frames)
 
This was a pretty gross experiment -- there was no analysis on which frames to drop or any hints about the missing frames... they were gone, just gone!
 
The resulting video was surprisingly good and it used a file that was 10%-30% of the original file size.

apple will jump on it.  they will come out with new equipment that supports it and send the the older devices H264 versions  - simple.  

post #31 of 92

Ziilabs is already working on integrating HEVC into ARM based SoC.   They aren't the only ones. 

 

http://www.eetimes.com/electronics-news/4236490/ZiiLabs-samples-stem-cell-Android-SoC

 

 

I see it playing out like this. 

 

 

Those with newer hardware that can decode HEVC will get the smaller data download.  Those with older hardware will get the larger streams.   Those running 

afoul of bandwidth caps will naturally be more disposed to upgrading their hardware if HEVC support was there. 

 

I'm excited either way.

We have two libraries on our Mac and the ATV finds them just fine. One for each user.  The mac wakes on LAN so no problem there either. iTunes is in the login items for both users. I'm not understanding why this is a huge problem? If you're a laptop only guy and worried about battery life by enabling wake on LAN, get a crappy old Mac Mini and stick in in a dark corner with your HDs.

I'm the only computer on my network that is unthrottled so I suck all the bandwidth from everyone else if I start watching a movie. I'm getting every bit of 100 Mb/sec file transfers. I should try in Chrome to see if there is a difference.

I see it playing out like this. 

 

 

Those with newer hardware that can decode HEVC will get the smaller data download.  Those with older hardware will get the larger streams.   Those running 

afoul of bandwidth caps will naturally be more disposed to upgrading their hardware if HEVC support was there. 

 

I'm excited either way.  

 

Thanks for the link... though I'm disappointed that it appears to be Android exclusive.

 

I am also disappointed that Apple appears to have no implementation of the new WiFi standard... 

 

I guess I'm just spoiled because Apple usually leads the pack in introducing new technology.

How does it see both libraries when only one user is logged in?

 

 If you're a laptop only guy and worried about battery life by enabling wake on LAN, get a crappy old Mac Mini and stick in in a dark corner with your HDs. 

 

Nope, but I shouldn't have to waste $600 on a computer I will never use for any reason just to do something my hardware is already capable of doing.

mkv is only a container, usually holding mp4 video anyway. Therefore, it seems to be an unnecessary extra enclosure (hello AVCHD).

  • dropped some of the frames -- for instance 3 or 4 out of  5
  • converted the resulting frames back to a video using QuickTime 7
  • used Optical Flow to smooth the video (generate missing frames)
 
This was a pretty gross experiment -- there was no analysis on which frames to drop or any hints about the missing frames... they were gone, just gone!
 
The resulting video was surprisingly good and it used a file that was 10%-30% of the original file size.

Cool research! I think Handbrake (or x264 CLI) does something similar if you crank up the B-frames, though too many breaks hardware playback on some devices.

 

I generally use pretty aggressive Handbrake settings, since a longer one-time encode is worth endless decoding of smaller & nicer files.

You clearly don't need any advice from me but JFYI I am on vacation on a crappy Comcast connection which I rated at <5Mbs. I of course plugged an AE in to the back of the Comcast router for my own WiFi use. Running ML on a MBP i7 I just watched the 5 minute plus video on Apple web site (retina display) without a stutter or dropped frame using Safari.

So like he said, the smaller the files.
