Dropouts & dead CCD pixels. Yucky.

Both are problems that you hopefully will never have…but I’d venture to guess that if you do experience one of these problems, you will find out in post-production…not during the shoot, when you can rectify the situation.
Dead pixels can be repaired by a camera service center, and sometimes they occur in areas of the image that “don’t really matter”. Some editors have had success with masking the pixel with nearby footage.
Dropouts can generally be prevented by not mixing tape brands/stocks, regular tape cleaning passes, etc.

But of course, you will discover your issue in post-production. Cleaning the tape path now is a little like shutting the gate after the horse has left the barn…

DH_Reincarnation is a filter for Final Cut Pro that can intelligently replace up to two dead pixels at a time.
And the DH_Dropout filter allows you to scale, move, and rotate up to two fields to aid in repairing a dropout problem.

Best of all, the filters are only $10 each.
