The DJI Osmo is just the core of that system - theres a driven, baby cineflex turret around it by that company. That's what they're really selling.
Presumably a development model as when the Osmo gimbal is working you see it does its thing just fine but when the turret pans it is too fast and is undamped on the start and stop of the movement across that cloudscape. Soft start motor controllers would sort it.
