Hey Stephen...

first thing I noticed is that you are getting a "pulsing" effect ...  
should be a consistant 120Hz buzz.  Second thing I noticed is that half 
way thru the video, the appearance of "light" ( sparks?? arcing??) 
occurs near the cap bank ( im guessing cap bank, the plate off to the 
left under the coil base). Are you using a variac to ramp up the voltage??
Check for arcing problems in the cap area.
Seems that you are geting a 6-8Hz pulse on the rotory, I would get a 
strobe of some type and check to make sure the rotory is definately 
spinning at the 1800rpm( 60hz) or 1500 rpm (50hz). The pulsing effect is 
normally consistant with a rotory that isnt running at 1800/1500 rpm. 
Before I went to sync rotory, I used a standard 1760 rpm motor and had 
the same pulsing effect on the BIGPIG coil but it was a bit slower on 
the pulsing effect.
