Ah fair point, I feel stupid, haha. I guess I've just never had coaches who moved while I was doing an element or who made me do it from another angle in the interest of getting a 360 view. I still think a camera can have a 360 view though in the exact same way.Why not, in person?
If the coach is on skates, they can go anywhere on the rink they need to see the element from whichever angle they need.
If they're not on skates, they can still walk around the outside of the ice to different locations as needed, with some angles perhaps limited by the architecture etc. of the rink.
They can also ask the skater to try something again in a different part of the ice or with a different angle of approach, so they can see the move from a different angle.
With video, especially with a fixed camera position, that is not possible.
