Another possibility is it’s caused by your shutter speed beating against the frequency of the lighting source, although, I don’t know why that’d happen on only one shot. Do you know what kind of lighting was used? How did you shoot this – camera, codec, framerate & shutter? It could also be rf interference from a close transmitter that was only on during that shot. I’m not sure if there’s a way to get rid of it. You might try the limit feature in the 3-say color corrector to remove/change the color of the bands. Here’s a link to a tutorial showing how to remove banding in DSLR footage. Hope it helps..
