Some footage I have shot (screencap below) appears to be affected by what looks like color banding (?) in the form of concentric circles on the background.
Please can anyone tell me what might have caused this and/or how it can be fixed?
Have you tried changing your composition to 16 or 32 bit?

Is that vignetting there in the original footage?
Is this screenshot completely raw, unaltered footage?
