One camera-angle change per call: hide, show, trim, nudge, or remove. A camera is positioned by its footage session's clock, so there is no action that moves one by hand; nudge is how a slightly-off placement is corrected. hide/show exclude or return an angle from automatic picture selection without touching saved explicit picture choices. trim persists source-clip trim handles; nudge persists a small user timing offset without rewriting measured sync times; remove deletes the clip while leaving media archived. Pass the Episode's current revision and a caller-stable idempotency key with every action.
