Not really. You can try commercial third-party plug-ins like Deflicker and use multiple copies of your footage with blending modes to reduce it, but generally such frequency rolling is nigh on impossible to cure. It was simply shot the wrong way.
It's called rolling shutter and there are plugins to help remove it, but they don't always work very well.
You've probably learned a good lesson. Rolling shutter is a fundamental issue when shooting with DSLRs; it's in the DNA. You, or your shooter, need to understand the flaw and either compensate with a different shutter speed or plan your shots so the movement is not going to produce the artifact. Or you learn to live with the artifacts if you cannot reshoot.
Search for ROLLING SHUTTER on various wikis and DSLR-oriented sites to get a full technical explanation and some suggestions on how to compensate. Hope you find a solution that gets you over the disappointment of having flawed video.
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.
