120 fps is pretty slow. With a fast shutter speed, I'd expect sparks to
look weird. You'd get just a part of the spark, and if the camera isn't
syncd to the coil's spark gap, it could look very strange.
If you saw this in Australia, where the line frequency is 50Hz and the
camera were 120 fps, then there's likely to be a weird stroboscopic
effect as the camera shutter rate "beats" against the TC's spark rate.
(unless it's a DC coil).
but at 1000 fps or more, you should be able to see soark growth.
