... Must be a 360 gimbal.
Difficult to say. Depends whether it is a one-man or two man setup. The extreme distances suggest FPV - which needs a fixed camera. All the 360's, backwards tracks and generally deliberately framed shots suggest a gimballed 360 camera mount but the occasional shadows do not reveal a huge camera mass underneath what I reckon, from the nimble flying, must be a quad. In the 'Testing 1 2' video the props are visible at the beginning and later they are not. This suggests at least a Tilt stabilized camera.
In 'Up & Up Early in Venice' is that the pilot hunched over right at the end on the steps? If it is where is the camera operator? But if it is a one-man show, how the hell does he fly all those circles and backwards and under rails and arches etc.
Whatever, this is really brilliant use of the platform and a benchmark for everyone here.
