Go To http://www.apple.com/quicktime/player/specs.html to see the system requirements for QuickTime 7.
A 400mhz G3 is the minimum requirement, but the purchased video playback requirements are a lot higher - 500mhz G4.
The trailers you are trying to view may be slightly more forgiving than purchased video clips, but I strongly suspect a 400mhz G3 just isn't quite up to being able to view the majority of today's video clips.
do you guys think it is the clips or the QT version?
Because i did not have this problem in the past. i mean it was always a little slow, but now it is basically unwatchable.
If it is the QT application, anyway to get/install earlier versions of QT? Any suggestions on which version is best suited for our G3s?
I have an iMac G3, 500 mhz, 500 meg RAM and DSL, 10.3.9, QT 7.0.3. Until Apple recently changed the Quicktime movie trailer site, I could watch any of the non-HD movies just fine, even the "large" ones. Since the changeover of the QT site, I also can no longer watch the large or most of the medium-sized trailers. Even the small ones aren't always so good. I can understand the HD trailers being too much for my old computer, but it makes no sense that in the space of two weeks, I can no longer watch the regular trailers. I don't see how my computer can be at fault. What changed was not it but the QT version and the QT movie trailer site
what you guys are experiencing is the downside of H264 which Apple has recently changed all of it's trailers to... it can be a very beautiful codec but it is a hog when it comes to the DECOMPRESSION stage... which is what you are doing at home.
yea... your older iMacs just can't keep up.
I should clarify, I don't know that apple is REcompressing all the old files but they are compressing everything new in H264.
I think quicktime 7 is broken for older cpus, and needs to be fixed. I
have a 500MHz ibook G3 with 640MB and Quicktime 7.0.3, and all of a sudden quicktime and iMovie have become unusable for large movies.
I am no longer able to watch movies I created on this laptop in iMovie!
iMovie itself is no longer usable.
VLC has no problems.
Is it possible to go back to 6.5? I foolishly updated both my machines at once.
I have the same exact equipment but do have 640 mb of RAM. I have had the same problem. I may be wrong but I think the slow processor speed is just not enough anymore. Still have QT 6.5 which I still use instead, however more things require QT7. I've reached my limit and am waiting for the new iMac G5 w/iSight 20" to arrive.
I'm having the same problem with QT 7.0.3 and I've got a Dual 1Ghz G4 w 1.2 Gig of RAM. Surely it's not my processor! iMovie is doing the exact same thing. Makes it impossible to do any editing.
This all started for me after I lost my QT Pro license when I updated from QT 6x to 7 (yep, didn't think about it till it was too late :() and then tried unsuccessfully to go back to version 6x. In the end I completely reinstalled QT 7 and paid for the PRO license.
It seems to play ok if I open a file and play it from the beginning, but the moment I skip ahead in the timeline it slows to a framerate of between 1-3 and grinds to a halt. I don't know if it's something I did when trying to go back to version 6x - maybe I corrupted a library file or something - or what.
I'm on OS X 10.3.9 so it SHOULD all work fine.
Anyone have any ideas?
Well I've gotten to the bottom of my problem. I hope it helps. Apparently it's a bug between QT 7 and my Digi 002 (pro-tools) Audio Interface. At the moment there's no solution, and from what i've read, reinstalling back to QT 6.5 doesn't fix it!?! So any one running a Digi-Design audio interface with QT 7 is going to have problems it seems.
When I turned off my Digi 002 and used the crappy built-in mac audio card both QT and iMovie worked no problems.
True! VLC and MPlayer are using the same codecs and play movies sooth, quicktime 6 too. This situation is realy strange coz some of my old avi's seems to be more processor hungry on Quicktime 7 than HD 480 movies coded in H.264!!!
Is it possible that Quicktime 7 is worse optimised than its predecessor? How can it be that its working slower than open source players on the same codecs?
