Why do some digital cameras distort when shooting Tesla coil lightning arcs?

M$Vertical smear refers to a common CCD-related issue that most video professionals are familiar with. Since the entire image is being captured at once on a CCD sensor, shots of bright lights can often have a vertical haloing effect, causing one column of pixels to appear brighter than the rest. The problem looks something like a lens-flare.

This creates a condition where a tiny bit of the very bright arc gets reflected off of the surface of one of the lenses, which then gets reflected back toward the sensor. Repeat this for the number of elements in the lens.
If you look very carefully at the video, you can see that the patterns of the distortion follow that of a portion of the arc, which further bolsters my belief that this is the cause.
Remedying this could be difficult, because even the most expensive Anti-Reflective coatings can never completely eliminate internal reflection, particularly in extremely high-contrast situations like this. You may, as has been suggested, end up having to resort to post-processing to fix it.
Once I find a good source (that's not wikipedia), I'll add it in here.

When the E-M field is affected by the person interacting with it, the field and magnetic values will change.
I liked the video! I suggest using a longer lens to get further away and maybe some better lighting for the next one.
