A useful tool of these VHS tapings is to view the
arcing that is taped frame per frame, which shows
1/60th of a second time intervals. This is typically
done by pressing pause on most tape selectors.  In one
of my early tapings both the primary and secondary
arcs positions could be seen in the same frame, and
these do not seem to correspond in time.( Showing that
primary and secondary arcing are separate in time)
Tapings of Mark Metlicas large coil showed that frame
per frame,many empty periods of non arcing exist,
which seem feasible for a very low natural res
frequency of long wire length. It might be useful to
also know that a mpeg conversion is translated to a
selection of 30 frames/sec from the VHS copy, and this
might result in a differing final copy of your
original VHS. I found this out by VHS taping a rapid
neon blink discharge to earth to find its frequency,
which could be found by counting the empty vs lit
frames on VHS tape review. Doing that with the VHS
taping itself showed 12 hz, but the Dazzle mpeg copy
showed a lower frequency when put through the same
frame count tests. From these frame count tests, it
seems at least like several 60 hz AC cycles go by
before secondary arcing is seen on taping.
