Quicktime Pro 7.66 now has Green screen?

I have it also.... Only when the video is opened or paused... or when trying to scan through it...

Plays just fine...

but makes doing quick edits using pro pretty much impossible....

You are not alone....

and I guess there are only two of us using quicktime 7... so probly not much action to get it fixed.

I just noticed this myself (and I recently upgraded to 10.7.4). I tried it on several movies of various formats (that I'd made), and they all exhibited the behavior. Since I knew that videos I'd made a while ago didn't have the problem, I started going through old videos systematically. None of the old ones exhibited the behavior. I tried newer and newer ones --- still no problem. Finally, I tried the first one again, and it no longer did it --- it paused and scrubbed just fine. So: INTERMITTENT.

I have the same issue, but mine's not intermittent. Seems very consistent. Also, I don't get the green screen when opening the same file in QuickTime X.

I don't get green screen when using QuickTime X also... But who wants to use QuickTime X?

Exactly!

I'm having very similar problem. I get a green screen when I open videos or stop and scan through. However it's seems to be related to H264 video mostly. Has anyone heard of any solution to this problem???

Another problem I've experienced is that if I make an edit to the video and export it, I get a black screen. So the video is not being saved at all...

I haven't heard of any solution. The videos I've tried have been H.264 as well. I just tried something in Animation. Seems to be ok.

Certainly there are more of us using QT7 and Apple needs to take action asap. I make quick edits very often and it is annoying to not have access to real time scrubbing.

Where do we line up to protest?

This is a reply to all the above....We all paid our $30.00 bucks, and now we aren't getting our money's worth. I've bombarded the feedback site with FIX QT PRO 7....IF IT IS NOT FIXED WITH 2 WEEKS I WILL DEMAND A REFUND. You got to hit them in the pocket book. When this first happend with the green screen and grayed out loop, I took it to my local NYC Apple Store..everyone is sympathic, but none can help. Forget calling the 800...My next step is to call corporate sales and speak to them....Remember folks, we are being gypped out of $30.00. And remember this...Apple didn't warn any of us of the consequences on some of the software if we elected to go to 10.7.4.....Complain, complain, complain....www.apple.com/feedback.....go to the QT icon, and let them have it.

I filed a bug report with Apple about this. I also found a work-around for my MacBook Pro: change from the integrated NVIDIA 9400M to the discrete NVIDIA 9600M GT. QuickTime Player 7 then immediately displays all the formerly green-screened movies properly.

If you're like me and have an older MacBook Pro that cannot change cards on-the-fly using stock Mac OS X, I highly recommend using Cody Krieger's gfxCardStatus. It adds that feature, and even for newer MacBook Pro owners it's useful so you can see when apps are triggering a switch from integrated to discrete cards.

Good luck!

Glad it worked for you too!

I'm curious, are you sure it's working for you when in "integrated" mode and not working when in "discrete" mode? You can double-check this by opening System Preferences and going to Energy Save. If "Graphics Card: Better Battery Life" is selected then it's on integrated while if "Higher Performance" is selected then it's on discrete.

It would be very interesting and make less sense to me if our situations are reversed.
