For the record h.264 will play fine. HD streams even play fine on a 1ghz ibook. These guys can just be such idiots...
On your 1ghz iBook, what does your processor meter say when you are decoding h.264? Is it more than 95%? If so, then this seems to match up with what the article says--it plays acceptably on G4s or better but is at nearly 100% on anything short of a G5. It stutters on a G3. The argument isn't that it won't play acceptably on a 1GHz G4--it's that it will max out your processor.
And for the record: the iBook doesn't have a high enough resolution screen to do HD. It's only 1024x768. You would have to have a 1024x768 video stream playing at full screen to even get close.

You can view HD footage, you just can't see all of it at the same time without resizing the window.
And the MOSR article seems fairly accurate, if a bit cynical. His point about H.264 encoding is pretty true, especially when the encoder implements all of the H.264 specification. We see for sure when Tiger is officially released.

well when they say PLAYING they dont' list any sizes or anything? lol apparently to most people h.264 is an entity unto itself. It's a VIDEO codec like .mov, or mpeg or anything. It's a nice format. At dvd resolution of 720x something i'm at 58% CPU while opening a 200mb photoshop image, and downloading another file at 250/k a second. The h.264 is playing from the DVD drive....
Everything is fine....
This isn't like pixel or anything. It's designed Pixel is about 50 times more cpu expensive and it runs just fine on my g5.
Major weekend dirt Part 2: CELL, Apple, and H.264
Two of the biggest technological leaps forward in 2005 may be very much inter-related when it comes to Apple, according to the latest Cupertino recon to cross our desks.
This being the Year of HD Video, H.264 is an extremely key technology for Apple. This advanced AV codec offers greatly increased high-definition video quality while also reducing file sizes.
It's a headline component of Mac OS X 10.4 Tiger and clearly the foundation for major Apple advancements to come. But all those advantages over existing video codecs come at a price -- greatly increased resource usage for encoding and decoding.
These two paragraphs are the BS
"No personal computer on the market today -- not even the most powerful, most expensive dual-processor Intel Xeon or Apple G5 -- is really up to the task of processing H.264 video efficiently.
Even on the latest dual 2.5GHz G5, decoding H.264 video demands a much larger portion of the system's resources than playback of video encoded with any other popular codec. "
A fun example (not really pertaining to this thread) is a screen movie capture I did using h.264 codec. It was 1024x768 for 10 minutes. the entire file was 34mb. compared to another format that was shittier and weighed in at 120mb

I didn't read beyond this. .mov is not a codec.

okay well technically ".mov" is just like ".avi", it's a container for video. I clearly understand "video". I was pointing out that some people "macosrumors" like to make things seem like magic.... You can play h.264 in mplayer in 10.3 if you want or encode to it with ffmpeg.

Technically? They're completely different things. Also, it's Pixlet not Pixel.

How is encoding that bad... I ripped some music videos into H.264 with Handbrake recently... granted I can't watch em yet, but they didn't take seemingly much longer than when I would use divx for my DVDs.
