Hi Michael,
Thanks so much for getting back to me! Double-clicking did load it into my Viewer correctly, however using the Frame Matchback option did not - it still remained black, with all of my markers and audio, just no visual.
I did not trash my preferences (yet), but I realized after I had posted to Apple that I had made a duplicate copy
of my project, and so I reverted to that, where everything was fine. The problem all started when my phone rang and I think I hit a key (or something) then it was offline (all thanks to a telemarketer).
Would my preferences need to be trashed if it works fine in another project?
🙂
Here are my clip specs:
