My video thumbnails in Aperture (version 3.4.3) are scrambled. Sometimes I can see part of a reference thumbnail frame (often in monochrome or with a single color overlay, like green), sometimes it's just all snow.


1) I just restored my mac mini from a time machine backup.

2) I also just imported an iPhoto library


If I browse to a pre-existing (before Time Machine restore) Aperture project, the correct thumbnail appears briefly before changing to the scrambled version.


When I select the video for playback all I get is a blank Viewer window (not video content, no controls, no playback).


If I browse to the source file via finder the video thumbnail displays and the video plays back correctly.


I have tried:


1) verifying and repairing disk permissions

2) repairing Aperture permissions

3) repairing the Aperture database

4) rebuilding the Aperture database

5) regenerating thumbnails (select video Photos->Regenerate Thumbnails) (thumbnail changes, still scrambled)


I don't use Aperture often so I'm not 100% sure when this started, but it seems to be after this current restore as supported by the brief correct appearance of old video thumbnails before they update to the scrambled version.


OS X 10.8.2

Aperture 3.4.3

Example of affected video:


QuickTime movie
