quicktime 7 HD on powerbook

[maxsquared]

I don't know if it's just me, or everyone else, I just installed tiger which I just got from applestore regent street. then I went to download a hd trailer (1080 one) it runs really really slow.

Is there any thing I done wrong or everyone has the same problem

[Bling3k12]

Could you elaborate more? What's the video, maybe I could check it out on my PB.

The bbc promotion one (1080)

I think I've got the same spec as ur pbook, but only I have a radeon 9700 card instead of 9600 and 1 GB ram

I found this on Apple.com

Recommended Hardware Configurations for H.264 High Definition (HD) Playback

To play high definition video, a large amount of data must be processed by your computer. A powerful system will deliver the best playback experience.

For 1280x720 (720p) video at 24-30 frames per second:

    * 1.8 GHz PowerMac G5 or faster Macintosh computer

    * At least 256 MB of RAM

    * 64 MB or greater video card

For 1920x1080 (1080p) video at 24-30 frames per second:

    * Dual 2.0 GHz PowerMac G5 or faster Macintosh computer

    * At least 512 MB of RAM

    * 128 MB or greater video card

I'll test your file out to see how it fares on my machine... but it seems that G4 people are left in the dark for H.264 HD content in QuickTime 7. :(

Edit: I just watched the BBC one... boy, does this suck or what!? I had tried playing HDV content through VLC before and had the same results, so I'm not surprised at all. Too bad, I love HD!

This is worrying, I really want a powerbook, but it seem's they are just not good enough to handle many thing's. I mean come on, VIDEO.

[Knight']

Well, HD isn't just normal video. Your right though, it sucks for G4 users. Maybe the "Mother of all thermal challenges" PowerBook G5 will be able to do HD :p

10.3.9 + QT7 = 12FPS at normal size.

I love this guy's "I mean come on, VIDEO" comment... as apparently the only type of video anyone will ever use again will be HD :rolleyes: By the time HD hits mainstream, I have no doubt every computer Apple makes will have at least 1 G5 core in it.

[Shetland]

ok, but out of curiosity, how well does it handle normal video (preferably tell me for formats such as QT, WMV, MPEG etc)

Either way I dont expect to be buying for a long while, so in a few revision's time;)

[RadishTM Veteran]

All other formats work pretty well, on my Mini anyway.

Radish?

Bad performance with that video on my PowerBook in my sig. I have the SharkTale trailer which is 720p, and it stutters some still on either 10.3.9 or Tiger. I can't wait for H.264 on the PC, I can watch those videos just fine then, LOL.

[shodan]

Well the 1080i videos i've tried sucks on my iMac G5 1.8, while all other "normal" contents in H264 play smooth.... bythe way, i don't think you will notice too much of a difference between the two of them on a normal computer display.

[maxsquared]

where did u get "normal" contents in H264? I think trailers on apple.com are still in H.263 or other formats, no?

Well no, on the quicktime page, you'll have a link in the top-right corner to HD videos. There you'll find some trailers in H264 codec, "normal" (1228x544) and for some of them even the 1080i version.....

[Bling3k12]

The Tiger Seminar was encoded in H.264 and works just fine.

Where did you find the access to the Seminar?

It says you had to preorder Tiger, which I did on the very first day, but I couldn't find any place to watch it....

The 720p trailers (1280x720) run fine on my PowerBook. There are a few dropped frames according to QuickTime but I didn't really notice them. The "Batman Begins" trailer in 720p is awesome. :D

I highly doubt it will run 1080i at more than 5fps though. Besides, why would I want to run 1920x1080 pixels of video on a 1280x854 screen? :laugh:

[cq_]

people its 1080P

[PureEdit]

I can play most video very well on my iBook G3, but not this HD stuff.

[SapUMBC]

people its 1080P

Thank you, Captain Grammar :no:

[Elliott]

My 12" PowerBook does 720p H.264 video quite well. It's the 1080p version that my PowerBook completely crawls on. This doesn't mean H.264 is useless on PowerBooks. It just means HD video encoded in H.264 above 720p doesn't fare too well.

[VGVL]

people its 1080P

585857035[/snapback]

I thought it was 1080i. No wonder it needs a Dual G5 to play. :laugh:

What I meant was all content on www.apple.com/trailer is still in h.263 format except those hd trailers are in h.264 format

[TheLegendOfMart]

people its 1080P

585857035[/snapback]

No its not, i think youll find its 1080i, 720 is P

[maxsquared]

720 is p 1080 you get both i and p, i think the p one is american standard and i is european standard (or the other way around, not really sure

[TheLegendOfMart]

1080 supports progressive scan, but to save bandwidth they interlace it so 1080i is commonly used, 720 can only be progressive.
