Quicktime Pro 7.66 now has Green screen?

Hi,

We just upgraded to LION 10.7.4 and I'm noticing on a few of my Quicktime movies - when paused, the screen turns green? THAT'S never happened before. I'm sure it's an upgrade issue, when I go back to our clone from last week, it doesn't do that!

We use QT Pro 7.66. on a MacBook Pro (about 1 1/2 years old) - always perfect results, but now this?

No big deal, just a little annoying. It only does this on a few of the movies we've exported out of Final Cut Pro. Can't find the pattern?

Anyone else seeing a green screen when paused? I'm lonely out here! 🙂

Thanks,

Larry

Thanks, Brain. This solved the problem for me on both computers. This article seems to suggest that this component enables accelerated H.264 playback on specific GPUs, including my NVIDIA 9600. Without loading a big H.264 movie and running a test, my guess is that performance on H.264 playback will suffer without the component installed. But it beats the green screen.

This worked for me too; thanks a lot.

+1, no more green screen with this component in a separate folder! Thanks for your hack!

I had a talk with Apple support in Germany recently.

The green screen problem seems to be a registered bug.

They recommend the workaround Mike Stitzner describes: open a H.264 file in QT X and keep it open for the time working with QT 7 Pro. Then the green screen doesn't appear.

Apple said they will be releasing a bug fixed version of QT 7 Pro shortly.

I removed the AppleVAH264HW file also and it worked for me. Thank you Brain.

i dont think that the AppleVAH264HW extension is the direct culprit in this, but removing it does make the behavior cease.

i had a test machine set up on an unused hard drive which still had 10.7.0 installed. As this behavior seems to have presented itself after the 10.7.4 update, i compared the AppleVAH264HW from 10.7.0 to 10.7.4 and there is no difference... file version is still 3.0, same creation date. i copied over the AppleVAH264HW from 10.7.0 into my 10.7.4 machine and restarted... and the behavior is still there.

so, it would seem that even though removing AppleVAH264HW from your quicktime folder fixes the problem, it is NOT the source of the problem, but something that is calling that extension in an incorrect manner.

anybody try out 10.8 yet and see if this still exists?

10.8 seems to fix it for me.

Me too, 10.8. obviously resolved the problem
