I suspect it may be moray patterns caused by pixel sampling that Canon does to make video HD video out of the 12MP sensor in your DSLR. I don't think this has anything to do with Rolling Shutter. Depending on the shot there are some filters that you can use to clean up these interference or moray patterns caused by horizontal and vertical detail in the shot. It's kind of like what happens when you shoot someone with a tight pattern on their neck tie. It dances and glows as they move. Herringbone or hounds tooth suits do the same thing.
