MacCentral reports (http://maccentral.macworld.com/news/2004/04/19/videocodec/index.php?redirect=1082424411000) on Apple demoing a new high quality video codec at the NAB conference.

The newest HD codec is called h.264 or "MPEG-4 Part 10" and represents a "flexible and very high-quality codec"

Unlike other codecs, h.264 is scalable, allowing content creators to write their content for everything from the newest 3G phones to HD, and everything in between.

As an open codec, there were a number of companies demonstrating h.264, though Microsoft was notably absent.

This potentially makes me very happy. h.263 has been my favoured codec for a while now. I've found it much better than Sorenson 3 for video with a lot of motion. QT's MPEG-4 implementation has really sucked up until now. It has pretty lousy scanning artifacts, takes a long time to compress from raw DV, and doesn't really compress files any smaller than h.263. Not to mention that MPEG-4 has no compatibility with QT5 or earlier, although it's doubtful that h.264 will either... Backwards compatibility was definitely a strength of h.263

This should necessitate Apple upgrading QT to 6.6. How else to get the codec distributed to everyone? I doubt they'd leave adding such a major enhancement to each users discretion.

We are desperately in need of a major QT rewrite.

AVC support is a step in the right direction but it's time that QT became
much more modern. QT is the reason why Final Cut Pro can playback 24 tracks of audio but cannot capture more than a stereo track.

I'm hoping to see QT become better at multitasking and it's core revamped. Who cares if it breaks legacy apps to a certain extend. QT 7 needs to be the new foundation for multimedia on Macs.

Apple will also need to support MPEG2 Transport Streams for easy HDV support for Final Cut Pro 5 and other video apps. How about improved scalers and deinterlacing? Audio should be beefed up to handle infinite Audio Ins limited only by hardware.

Hell add OpenGl and the ability to handle overlays and other broadcast effects right in QT. Imagine if QT gave developers the base features to create Home Theater PC applications very easily. That would rock. I have high hope for Apple with QT.

Plus document it very well and push it for developers. You know the first Multimedia wave was a joke by todays standards. We were happy then to have sound video and computer graphics all in one place. Today multimedia means surround sound, 3D and robust video. It's time to get QT caught up

You're talking about Sony's Blu-Ray discs. They use a Blue laser of course and hold up to 50GB of MPEG2 data on a disck

http://www.blu-ray.com/

The DVD-Forum however has chosed the HW from Toshiba called AOD which uses smaller discs which are 25GB max I believe but they use a more efficient Codec called AVC to cram 4 hrs of HiDefinition video in the same space it takes Blu Ray 50GB. That's how efficient AVC will be and this is the new codec we're talking about. AVC is the official name for h.264.

This is great news. Apple will have native support for two out of 3 mandatory codecs for the next HiDef specification(these are VC9 from Microsloth, AVC and MPEG2)

I think this will lead to QuickTime 6.6/7 and maby, Apple will start shipping PowerMac G5s with the ability to read Blu-Ray disks. Or Apple could ship PowerMacs with the ability to burn DVD9 disks, instead of the lousy DVD5 that only hold 4.7 GB.

What ever happens, this will result in a new QuickTime Pro version, get your credit card ready. :)

i think it will coincide with the release of starwars episode iii for a couple reasons

1- more people will watch a starwars trailer
2- the people that will watch it are likely to want to see it enough to download a new version of quicktime to be able to see it
3- i believe that the episode i teaser required quicktime 3 and/or the episode 1 trailer required quicktime 4 (first deployment of quicktime 4)
4- the episode ii teaser/trailer required quicktime 5 (first deployment of quicktime 5)
5- the timing of the release of the teaser (probably this fall) and the trailer (winter) are about right for a major revamp for quicktime

hopefully this will continue... maybe a quicktime 7 surround sound trailer? my fingers are crossed

You have absolutly no idea how much I agree with you in this statement. Fortunately, Quicktime seems to be recieving a lot of attention from Apple, and I hope that they can managed to do a lot of the work they have planned. Just wish that they would give developers more of a look at what those plans are :( .

They already ship dual layer burners in the powermacs. The Pioneer A-07 drive has been demonstrated by pioneer as being able to burn dual layer disc with a firmware update that is coming this summer.

The next revision will probably have this as an advertisesd feauture since manufacturers will have these drives shipping in may and june which matches up for wwdc.

yes indeed. what would be great is if H264 could replace Xvid and divx.. I don't know too much about this stuff, but if I understood what people are saying here, the 264 could do this. The fact is that the quicktime mpeg4 is horrible compared to xvid, but I guess they are for a bit different purposes anyway.

My point is (if there really is one) that I'd like Quicktime to be my primary player again (instead of MPlayer, which is nice, but not as nice as quicktime), but I need to be able to encode my movies to a reasonable size (I rather don't use the DVD.. much easier just to doubleclick a file) so that I can still watch them with QT without any hassle.

the a-07 drive can burn 4.7gb dvd-r and dvd+r discs, but macs cannot currently tap the +r technology until this firmware update you mention.

however, these are both single-layer discs. dual layer discs can hold about 9gb of data... the first burners for these are just coming out and have yet to be standard issue in any consumer system offered by apple. yet...

Pioneer demonstrates dual layer recording at CES, only firmware modification needed
Posted by Jan Willem on 12 January 2004 - 15:33 - Source: AVWatch


Pioneer has demonstrated dual layer burning during the CES, the technology exhibition in Las Vegas. The company succeeded recording to two layers DVD-R in October 2003 and now firstly publicly demonstrated the technology. In the booth of the RWPPI (RW Products Promotion Initiative) they wrote 100 MB to each layer. The discs were read back by a normal DVD player.

Intresting however is that the company used a Pioneer A06 burner with only a modified firmware. According to the company only a firmware modification is needed in order to make a DVD-R drive write dual layer discs. The disc was written at 2 speed. The DVD-R dual layer specifications have not yet been passed by the DVD Forum.

This may have already been written, but the Episode 2 trailer requicked QT5 Pro to view at the"large" setting.. That made soooooo many people unhappy, that they eventually dropped it down to standard QT5 after a time.

i think it will coincide with the release of starwars episode iii for a couple reasons

1- more people will watch a starwars trailer
2- the people that will watch it are likely to want to see it enough to download a new version of quicktime to be able to see it

I haven't read the whole thread, but just to let those interested know, they had a demo of this at the Apple booth at NAB. It was VERY impressive, in fact, they were showing native HD resolution files, that were incoded with the codec, and I could tell no difference, it still looked HD. In fact the Apple rep at the booth said that they gave the compressed HD footage to the FCPHD testers without telling them it was conpressed, and they couldn't tell either. The compressed version of the HD Harry Potter 3 trailer that they were showing was about 190 megs in size. The file was 2 minutes long and had a resolution of 1920X1440. It was very very impressive, and puts M$'s HD compression codec to shame.

tortoise
Apr 20, 2004, 06:26 PM
It is a very slick codec, and can put 1920x1200 HD (e.g. D5) into a very nice 4-5 Mbit stream. For comparison, H.264 (aka MPEG AVC) can put a DVD equivalent video signal into about 1-1.5 Mbit. In other words, it represents an integer factor improvement in compression for a given quality level. So with this codec they can fit very high resolution video onto a standard DVD format.

The downside is that H.264 requires BRUTAL quantities of CPU. If you are looking for a new use to max out the CPU on your spiffy new G5, H.264 encoding will do it, and decoding is only marginally better, at least at high resolutions. Most consumer PCs currently do not have the horsepower (nor bus) to do a high-res decode without dedicated silicon pulling some weight.

H.264 is a great thing, but it will take a while to really hit the market for consumer purposes until good encoder/decoder ASICs are widely available. You can't just throw an embedded CPU at it and expect it to work, as it requires far more beef than MPEG-2, and high-res vanilla MPEG-4 ASP starts to strain many systems.

As a web designer, I have been really disappointed by Apple's seeming disinterest in Quicktime Virtual Reality Studio. To my knowledge, the thing hasn't been updated since the OS9 days, and though I'm sure it would run just fine in Classic layer, there's no way I'm dishing out money on an app that I have to boot up Classic for. ESPECIALLY not an Apple app. It's shocking they are selling a non-OS X native app.

Hopefully, this news will bring about QT 6.6/7, and a new QTVR Studio along with it.

Unfortunately, he didn't direct any time frame onto the QT7 predictions. We all know Apple is working on something... we just don't know when we'll see it. My money is on WWDC for a preview of QT7 to be included with Mac OS 10.4 (Tiger?).

A new format is great but there is a heck of a lot of video out there and quicktime can't play a fair portion of it....

The single most important problem i have with supporting installed QT is the video format issue. For gods sake take a page from the open source community and please add support for EVERY format that you can find!!.. if it can be played on windows then QT should be able to PLAY it.

the first "user" response when QT can't play a video clip is that " QT sucks" or "QT is broken"...the bottom line is that end user does not care about the fact that the clip was compressed with an older codec (IV3 or IV50) or some of the stranger codecs ( MP43) ...the end user does not care and does not want to to know. And the end user will stick with the player that opens the most clip the fist time.

Want quick time to outrun Windows media player ? Then develop a reputation as a work horse, "fits all solution". QT should play it all...end story

and i agree with the following in spades...

AVC support is a step in the right direction but it's time that QT became
much more modern. QT is the reason why Final Cut Pro can playback 24 tracks of audio but cannot capture more than a stereo track.

I'm hoping to see QT become better at multitasking and it's core revamped. Who cares if it breaks legacy apps to a certain extend. QT 7 needs to be the new foundation for multimedia on Macs.

Apple will also need to support MPEG2 Transport Streams for easy HDV support for Final Cut Pro 5 and other video apps. How about improved scalers and deinterlacing? Audio should be beefed up to handle infinite Audio Ins limited only by hardware.

Hell add OpenGl and the ability to handle overlays and other broadcast effects right in QT. Imagine if QT gave developers the base features to create Home Theater PC applications very easily. That would rock. I have high hope for Apple with QT.

Plus document it very well and push it for developers. You know the first Multimedia wave was a joke by todays standards. We were happy then to have sound video and computer graphics all in one place. Today multimedia means surround sound, 3D and robust video. It's time to get QT caught up

As I understand it, the original superdrive was an A05.

I recently purchased and installed an A06 to replace my DVD RAM drive in my sawtooth single processor 500MHz G4.

At that time I couldn't find any reference on US sites to the A06. I'm wondering if an A06 was released in the US or is the A06 a canadain model number for what is an A07 in the US?

If so it would seem that my A06 will be able to burn dual layers with the aforementioned firmware update. Or am I out of luck?

i couldn't agree more. mplayer is my default for EVERY single media format. one thing that pisses me off about setting default applications in os x is you set them by file extention, not MIME type. thus i have to set mplayer for both mpg and mpeg, which is annoying.

Personally I do not understand the hype of this except for QT's ability to DECODE the streams. Quality when compressing to a certain standard, at this modern days, has been repeatedly demonstrated to be so dependent on the implementation being used. As has been said xvid and divx kick Apple's implementation of the same standard, as does LAME mp3 encoder to Apple's iTunes (OTOH iTunes is blazing fast). I do not understand why everyone is so convinced that QT's ENCODING abilities will be worth a penny after seeing what Apple did with MPEG4.

Actually, Quicktime's encoding of MP3s is very good indeed, and its encoding of MPEG4 audio (AAC) is arguably one of the best available.

It is only the encoding of MPEG4 Video that lets it down so horribly.

I am not sure if more CPU intensive compression is the way to go.

The speed increases in bandwidth and the size increases in storage are out stripping CPU speed increase by a factor of 100 and 10 respectively.

In the future, we are going to be less concerned about the size of the file and more concerned about how much CPU usage it will require.

I would think it would be better to stick with a less CPU intensive compression format.

You could be right they are moving faster at the moment, but the key thing provded by this standard, flexible codec that performs well at an extremely wide range of bit-rates and qualities is that it can be built in silicon and deployed even in mobile phones. The wide range of applications of the codec brings with it commodity silicon and low low prices...

Besides, playback of H.264 is perfectly possible on your recent-ish mac. Maybe not at HD qualities, but certainly DVD and above qualities.

Where do you get those ratios from anyways?

.. if it can be played on windows then QT should be able to PLAY it.

here, here. i, too have switched to mPlayer b/c it plays 90% of the stuff i throw at it. i am sick of having to drag clips onto the icon all the time, but i've been reluctant to supplant QT as the default. guess i should get over that, huh?

this new codec sounds pretty sweet. i've been keeping up w/ the blue laser format battle that's brewing & was dissapointed to see M$ win out w/ WMV.

for anyone that needs a quick intro to the upcoming format wars, CNN did a pretty good overview: DVD Format War Looms (http://www.cnn.com/2004/TECH/ptech/04/19/ondeck.dvd.ap/index.html)

MPEG4 looks worse than other major codecs at the same bit rate, and the AAC audio files on iTMS often have tape hiss type sounds on them.
Apple has really screwed up in their choice of codecs. Someone has been feeding Steve a line of bull about the relative quality of these codecs.

Nah, the quality of these codecs is not in question.
Apple's implentation of them is. Apple MPEG4 Video is really bad. Apple MPEG4 Audio is good! - though arguably 128Kb/s is perhaps the lowest bitrate you could concieve of for distributing paid for audio content. 160Kbs would have been perhaps a better choice, but a significant increase in costs for Apple for the iTMS.

If this new codec is going to be used on things like 3G phones, it could, in theory, also work on a new video version of the iPOD, right?

LOL I don't know why I'm even responding to you since I doubt you really have a clue what you're saying. Anywhoo, out of some morbid curiosity, just why do you feel like MPEG4 looks bad and AAC has tape hiss sounds?

And please don't reference that extremetech Codec challenge done by that idiot Jason Cross. That article has been trashed in more ways than one for it's poor methodology.

I can confirm I saw mention of this at NAB.

Saw the new Harry Potter trailer at NAB (being displayed on a plasma screen to boot), and the data rate was 764K/sec for that file -- unbelievable. Couldn't tell it was compressed (maybe with a split screen, but certainly no artifacting, even when whisps of candle smoke floated across the screen). No banding. No pixelization. Not even 1 MB/sec.
Saw a (little) 320x240 quicktime compressed with this codec, and it's streaming rate was 20 K/sec and was easily better than anything I've been able to get WM9 to accomplish at 100 K/sec. Picture perfect. Unbelievable. And I'm an editor.

One does not offer proof of information that is available to direct perception, except to say "open your eyes."

Let's try to make this debate a bit more constructive.

Name the codecs (audio and video) that you believe outperform MPEG4/AAC in quality, file size, etc.

Duly noted. Been to an ear specialist lately? I don't dispute your claims about Apple's implementation of MPEG4(which isn't too hot neither is their MPEG2) but to catagorically denigrate the codec is folly. There are excellent and horrible encoder/decoder for all codecs.

As for AAC my ears tell me it's fine. However no two ears hear things in exactly the same way.

Not sure you caught my earlier post but thanks for driving home my point. The bottom line is that there will always be some new codec or a person who thinks one is better then another...Thus QT needs to support them all. QT is not a codec or a collection of codecs...its a tool to get the end user video and sound and in doing so needs to support the widest range of possible codecs. The end user should not be penalized for the encoders subjective decison that one codec is better then another.

Quicktime currently penalizes the end user ..broader codec support will help reduce that penalty and have the added benifit of increasing QT market penetration as it gains the reputation of " the frequently updated,fits all player "

Me and users I support only WANT ONE player...QT forces us to have more than one.

later
