holy crap. I never really think about things like this are done.
That was about 80 times more stable than i thought it would be
that is some SLICK camerawork (the type of camera being used helps stabilize the picture a lot too)
I believe that stabilizer is a gimbal, and let me tell you something, they are very heavy. I had to use a type of gimbal at my summer job, and your arms are sore within seconds if you’re not used to it. You have to position your hands just right so the camera doesn’t swing around too much, and with how unstable you are on rollerblades, that is very impressive indeed.
