I have Aperture 3.4.3 on a newly installed Mountain Lion 10.8.2.  It is a MacBook Pro which was running Lion. However, last week I had to replace at the Apple Store the hard drive and logic board. When my machine came home, I had troubles with the "blue screen", so installed Mountain Lion. The machine is running fine. I have run updates and it should be a fresh machine.


In Aperture, all of my movies function, but their thumbnails are blank or black.


I have run the usual three steps launching Aperture with Option Command. No change.


I have run Disk Utilities regarding permissions and checking HD from a Recovery boot. No change.


Done the restarts, Zapped PRAM, and done a Safeboot.


Any other thoughts?

    Is your Aperture library on an external drive or on your system drive?

    Are the videos imported into the library ore referenced? What kind of videos, what is the camera type?



    Have you tried to recreate the thumbnails for your movies? You can do that by selecting the movies and using the command "File > Generate Thumbnail".


    Or try to set the poster frame again. The movie poster frame will show as thumbnail in the browser. The poster frame can be set in the Movie Editor. Click the cogwheel, when the movie controls are displayed:
