Mark,

I have indeed tested the video for the electronic effect and have long 
denied fireball evidence appearing on video due to certain problems with 
the medium.

The sparks I have tested for were timed with a scope for 1000us duration. 
 I had to fire the system 21 times to even record one spark on video!!!  
The one time I recorded the spark, both the frame before and after were 
pitch black with no faint ionization.  The long persisting coil sparks 
are real, as I note ,and are very long lasting.  The air is virtually on 
fire and the plasma ribbon while being pulsed, appears to brighten even 
to the eye in real life and real time.  (super integrator)

I have yet to record on video a spark which brightens, dims, and then 
rebrightens and dims again in a single recorded strike.
