Though it may look fake and unreal and impossible and not allowed on Earth, the camera stabiliser in the video is completely real. You can't make it shake. It's like magic decided to defy physics and ignore gravity. All I want to do is park myself in front of a mirror and do as many twists and turns and spins as possible to see if I can get the camera off track. Like this guy.
The rig seems strikingly similar to the Freefly MōVI, a custom-made gimbal and 3-axis gyroscope rig that digitally stabilises cameras and costs more than $US15,000. Worth it for this much fun.
