Quicktime 7.5 has problems..... no really

This solved my problems with Keynote failing to export quicktime movies and sending to youtube.

Thanks,

I had the same experience. Editing in iMovie 6.0.3. QT 7.5 upgrade notice comes up on my screen. I'm going to breakfast anyway, so I close my project and do download. When I come back to edit stuff is goofy, but I do not notice until I drop fifty short cross dissolves into a slide show. When Big Mac comes up for air, I realize that stuff aint working right, so I decide to send the project to video tape and give the computer a rest.

When I get back, and hour later, the export is done. The video on the computer is choppy, but the sound is fine. The video on tape is black black but the sound is fine.

I look at another iMovie project on the internal drive. It looks the same. I open a QT movie on the internal drive, sameo sameo. I plug in and boot an external drive and open a finished iMovie project. It has the same jerky video perfect sound. I am going nuts.

Where do we send the killers? Why has it taken a week for QT developers to do nothing about this?
Who is in denial here? Is it just another Bush/Cheney coverup? We all expect better and more honest from Apple.

I have the very same issues, which include choppy video, no sound. Interestingly enough, my mp2 video files work perfectly well. I don't know if that has anything to do with downloading apple's mpeg2 codec after I installed QT 7.5, but those are the only files that work fine. I completed nearly all of the recommendations by Klaus1, except for the archive and install, which I don't think will help anyway. I really doubt that an archive and reinstall would be worth all the hassle. My next move will be to downgrade, which is also risky, but if that works then I will report the results, which would be proof that yes, indeed, the problem is with QT 7.5.

Ditto here with the choppy playback on iMovie, and for that matter Quicktime

Chris, Any solutions to your problems? I am having same issues but what is strange is when I play the qt file within Final Cut Pro 6 I have no problems, play back is smooth. When I play using just qt player the footage is jumpy. Thus when I put the clip into iDVD the bad playback still exists.

I have the same problems of dropped frames in Quicktime Player for 7.5. This only shows up in playing HD movies where 7.4 did not have this problem. When I updated to 7.5 from 7.4 I had no applications running except the updater, and repaired permissions before and after updating (I'm paranoid) and I have the same problems others have had. I don't use iMovie for anything, so I had no "projects" open or any running applications to interfere. There must be something either in the update itself, or some interaction between the update and the graphics card. I have the GeForce FX 5200, with revision number 0x00b1 and ROM version 2103. If anyone else is having this problem, you should check your graphics setup and see how they match up against working systems.

I have tried everything suggested here and nothing has worked to resolved the choppy video. I finally used Pacifist to reinstall 7.4.5 and Quicktime and iMovie playback are back to where they should be.

Same problem here. QT 7.5 cannot render some movies fullscreen on a 30" (ATI XT850 on a PPC G5 used as a media center, successfully over 3 years). It can render on a large surface but breaks if I try to go fullscreen. I do not recall problem with sounds.

Let me know how to contribute more details if needed.

I will either use VLC or try to re-install 7.4. I would prefer QT 7.4 (or 7.6 🙂 since I have several scripts to control the display.

You need the 7.4.5 dmg and Pacifist.

If you choose to go backwards from Quicktime 7.5 to 7.4, remember to save your Quicktime Pro registration number before deleting Quicktime.

Next, VLC is a stand alone program but will use your quicktime codec. FFMpex is also a stand aalonne program, but uses it's own Codec. You can watch an AVI file in this program to verify that it really does have sound.
Real player and Quicktime share !

I know, that we all use the software update software, but, Codecs in your library folder do not upgrade automaticly like your programs do.
Download perian 1.1, and install it. Then reboot. try your AVI files.

Maybe, but hey, how do I get that running bug you have?
