Sorry, I’m not a very “technical” person.

I’m using Windows 7 and Premiere CS5.

Not sure what you mean by “source of originating footage.”

When I go to thumbnail view in the bin, it just shows black squares. However, if I drop a clip on the timeline and export it, the exported version looks and sounds fine when played through windows media.

I have cleared the cache and trashed my preferences.
