Hi Jack,
Thanks for replying.
This issue occurs in AE and PP for me.
It doesn’t matter what I have on the timeline in PP. Could just be some photos. So it is not a CODEC issue, as far as I can tell. Also occurs with audio… instance if I preview an MP3 in the Source monitor… or place an MP3 on an empty sequence timeline.
I just went through a procedure to manually enable Mercury Engine support. Didn’t make any difference, but nice to know it can be done (assuming I ever get PP 6 working.
Would you post here what your hardware set up is. Thanks.
Mine is 2010 MacBook Pro, 17″
Processor 2.66 GHz Intel Core i7
Memory 8 GB 1067 MHz DDR3
Graphics Intel HD Graphics 288 MB & NVIDIA GeForce GT 330M
OS X 10.8.2
It is the GT 330M that supports Mercury Engine via CUDA, although Premiere Pro doesn’t include the NVIDIA GeForce GT 330M in its list of support cards by default. As mentioned, I manually enabled support for it to see if it was a Mercury Playback Engine (software only) issue at fault.
I found someone else online with the same hardware and OS, with the same issue. He managed to fix it by uninstalling all video aspects of CS6, and reinstall. I’ve already been through multiple uninstalls and reinstalls, to no avail. I guess he got lucky.
