Yep, I bet it is strobing caused because your shutter speed is prob 1/50 and the lights are flickering at mains frequency 50hz. Manually set a different shutter speed and all should be well.
Oh that wont help you knowew its shot will it ! Add some temproal blur, or motion blurr and the problem should be decreased. You may just have to find the lowest amount of motion blurr that wks. Cant think of another way.
If you post a link to some of the footage I can have a go at fixing it if u like.
