Classic film-continuity grammar — keep the camera on one static side of a scene's action axis, filming each character from a consistent angle/shoulder — applied to AI-generated dialogue scenes. Nothing in an ordinary prompt otherwise constrains which side of a two-person conversation the camera sits on, so an unconstrained reverse cut can flip to the 'wrong' side of the axis and the audience loses track of who is standing where. Fix: explicitly instruct the model to hold the camera on one fixed side of the dialogue axis and to always frame the reverse shot over the same shoulder. Used in practice alongside Reverse-Angle Environment References for Dialogue Continuity, which locks the room's contents across the same cuts while this rule locks the camera's position.
