Thin Lines on Footage

[markzimmstl]

On a single project in PP, I'm getting some thin, black, curved lines over the top third of the footage. It doesn't appear over mographs.  It's a big project (80 mins). Replacing the footage doesn't seem to help. TIA   - Mark

Thanks. I'll try these once I'm back in town.
