Can we play around with shot angles? For example, overhead shots.

Yes. Two ways, both with AI.

To change the angle of a frame you already have, select it on the Canvas, open Magic edit and pick the Angle tab. Choose a shot chip (Eye level, Low angle, High angle, Close-up, Wide, Over shoulder) or set the camera yourself with the rotation, tilt and distance controls, then Generate. The result replaces the frame in place, so your script and properties stay put.

For a true overhead or bird's-eye view, set the shot's Angle property to Top-down or Aerial (or say so in the prompt) and generate the shot with Tribe AI; the angle goes into the prompt. Both use AI credits at the rate shown.
