You can use virtualdub to convert it to divx. I use that to compress 8 gb 
dvd's (mpeg2) down to ~1gb divx files with no perceptible loss of quality. 
Prob get alot more compression with mpeg1, especially if you compress the 
audio as well to 96-128kb/s mp3 with the divx.

Hi All,


On Thursday evening Gerry, Dave and myself played with my DRSSTC at up to
6000 BPS at full power. We could compare the coil's operation at 40 - 300
BPS in a standard mode of operation to its operation at 1000 - 6000BPS in
the burst mode.


The 6000 PBS burst mode seemed to produce roughly 20% longer arcs than the
standard mode. The long and short variation with a small change in BPS was
still there. However the magnitude of the variation was less at full power.
The variation was approximately plus and minus 20% of the standard mode's
arc length. So it was significant still


The longer arc length at very high BPS seemed to be due to much hotter and
more sword like streamers. In the standard mode, the coil reaches a point
where longer T1 times simply do not make any longer arcs. But at much
higher BPS rates, the arcs seems to "shoot" better and longer by roughly
20%. Where the 300BPS streamers are a bit brush like, the 6000 BPS
streamers are very will defined spiders.


So the difference was not dramatic, but there was some significant gain in
streamer length. Most interesting is the form the streamers take at very
high BPS. They are a high pitched load bang almost like a hammer hitting
damped steel. They are not all all a brush discharge but very defined hot
mult-branched arcs. The streamers have a hot yellow color to them in low
light. The high energy 6000BPS streamers may be very unpleasent to get hit
by!! No one knows how they would "feel", but grate caution should be used.
Streamers like this are in very uncharted territory and the dangers are not
known.


I did seem like the 6000 BPS streamers worked best with the streamers
directed straight upward from a sharp wire from the center of the toroid. I
think Duane Bylund noticed this too many years ago with his solid state coils.


The coil took many secondary to strike rail and secondary to primary arcs
without failure! The DRSSTC protectors where the only real change and they
seems to do the trick! For the first time, the coil was used hard without
failure!


The camera video is about 29 minutes long and 300Mb in VCD format :-p I
have passed along a few clips to the DRSSTC fans, but I don't have a way to
distribute the 450G bytes to all 1500 folks :-( If anyone knows a super
good way to compress video without killing sound and video quality I would
like to know about it. I can supply tape in VHS and S-VHS... It is all very
visual but it is frustrating not to be able to show everyone. The fast
pulses need high quality video too...


So, the test seemed to raise a few more questions than answers, but it did
define basic limits to what very high BPS can do.


Much to ponder...


Cheers,

Terry
