Pretty much no. You have periodic frames where the video in a portion of the picture is slightly higher and then lower than the others.
If someone held a gun to your head, you could, frame by frame, mask the areas damaged and change the video gain until they matched all the other frames. You will almost certainly need color correction as well.
It should only take you months.
Did you have a real television monitor on the set? That would have warned you of this problem. Camera viewfinders don't always tell you enough to keep you out of trouble.
