[Matthew Wilson]"Hey Guys, Link to video below. I have some sort of flicker or banding?"
It's really tough to tell with the YouTube compression, but it almost looks like hum in the video from power. How was this shot recorded?
While there are some tools for fixing flicker, like AE's Color Stabilizer or GenArts Sapphire FlickerRemove, they are better suited for full-frame flicker, not rolling interference.
You could reshoot, or you can try to fix it with a levels or color correction adjustment layer and animated, feathered mask.
