I saw this guy at the NJ Wood Show last year. The bandsaw has the
lower guide removed and the replacement guide, which makes it all
possible, is a pricey $180 from Carter.
20 or 25 years ago at a Model Engineering Show in or somewhere near
London there was a guy demoing a power jig saw. For a pound or two a
child could write out his or her name on a piece of paper. He would take
a strip of wood and freehand that name in interlocking letters which
came apart. He did use a drill for the holes in letters like B. He went
just as fast as the guy in the video. He once broke a blade. It took him
less than 30 seconds to change. It takes practice and a good visual
sense. If you don't have the latter no amount of practice will help.
FWIW, It is not the guides, it is the saw and or blade. If you will watch
the video again you will notice the blade moving back and forth as he makes
the turns. A guide should prevent this type movement. The upper guide in
this video is certainly not doing any thing.
Additionally, I watched a MiniMax rep do the same thing with the blade guard
fully raised with absolutely no blade guides at all, top or bottom.
According to him you don't need guides if you have a good BS.
Further, I was fed up with tracking problems and noise problems coming from
roller guides. Some blades did well on my short lived Rikon some did
poorly. After upgrading to a Laguna BS it does not matter what kind or
brand of blade I use, all work well with little to no effort regauding guide
adjustments going from one size or brand to another.
It is true that the guides are not doing anything here since the guide
is all the way up.
I have seen this demo many times at the WW shows. And I noticed that
early on. At the time they were trying to sell the carter guide with
the single supported bearing behind the blade and the olson blades.
TWC (now out of business sorry to say. I used to get casters from them
real nice and inexpensive) was responsible for the demo.
The guys doing it had to have lots of practice.

Not necessarily. I have one of those Carter guides and it cost me
$80.00. The bottom guides are removed and the Carter single grooved
bearing is used in place of the normal top guides. The groove in the
bearing holds the blade from going side to side at the back of the blade
while allowing the front edge of the blade to turn and twist. This
twisting and turning when coupled with a narrow ( 3/16" or less ) blade
allows small radii cuts similar to a scroll saw. It is a pretty slick
device once you get the hang of using it.
