This week, Tested tests a motorized stabilizer for GoPro cameras: the Feiyu-Tech G3 Ultra. Like the gimballed mounts used for quadcopter cameras, this handheld rig can keep a GoPro Hero 3 or 4 fixed on its rotational axes. The result is video that is relatively stable compared to footage from GoPros attached with rigid mounts. Akin to a portable steadicam. They discuss its potential uses and compare some test footage.
