What quadcopter are you using, and would you recommend it? If not, what else would you recommend? The one shown in the video looks quite interesting, and very economical (I looked at the manufacturer's site for more specs).
I've been wanting to do this (aerial video) for years, but the Draganflyer and similar copters were either too expensive, too shaky, or incapable of using a decent camera.
Sorry to take this a little OT, but since the stabilizer is based on the copter, and if you go to the author's YouTube page and look at his other videos, some of them involve aerial video.
As for the stabilizer, it looks absolutely brilliant, and I want one of those as well.
Finally, since I don't fly quadcopters, and since I am thick to begin with, where IS he heading with this??
Well, where he's heading with this is a working stabilizer, which I think he mostly has figured out. If you didn't need to point the camera up & down, I don't think you'd even need the radio. I could be totally wrong, though. A kk2, or similar circuit board is used for a quadcopter's brain, and may be used here, too. It's what's used to level things out.
For aerial video, most in the know fly with a hexcopter, which has more power and is more stable. I'm just learning with my quad right now.

The video posted by the MoVI guy claimed to not be stabilized in post. If so, it was the most stable video I've seen from a cheap aerial rig. There was quite a bit of wind at the time (you can hear it) so it was taken under less than perfect flying conditions:
I'm not going to be much help with brands and money. I have a Futaba radio from my airplane days and the quad I put together myself. It's a Bumblebee. So all in all about $600.
