Thanks for the help, Tim. I enlisted Treasured’s software/service (by Aero Quartet) and was able to recover everything.
For future Pix240 users who find corrupt files like this after a power failure, I recommend the following:
1.) Create .img file of entire CF card SSD (what have you)
2.) Use Treasured to run a “Deep Media Scan” of the entire thing.
3.) Use the handy slices in iPhoto to determine if your clip is there, and follow the steps Treasured recommends.
Overall cost was $299 which is I think their highest tier of service. Certainly worth it. Their tech support was also very quick when the first “repair kit” had the wrong frame rate output.
