What are the seating skills of multi-person dialogue in movies?

In the form of dialogue between two people, there is basically no narration of third-party characters in film and television dramas, but a confrontation between the two sides. But in the interview film, it should be remembered that even if there are only two of them at the scene, they will not talk to each other, so they will not adopt face-to-face communication. In other words, there is little possibility that the included angle between them is 0 degrees.

Axis: an imaginary line between the subject and the people or things he plays with, or an imaginary line along the subject's motion path, used to set and maintain the direction of actors or behaviors in the scene.

Secondly, if the position of the machine remains unchanged, it is feasible to change from the outer triangle to the inner triangle. Two-person dialogue scene shooting; It's all taken by machines. Party A and Party B fought each other. They shoot A first, and then B puts the words together. As long as they don't shoot, they will keep shooting. Then switch to shoot B and A for the simple reason that it is difficult for actors to get into the state, let alone both actors. So we shoot separately and edit together later. This is more efficient. As for multiple camera, it is also a difficult or costly action scene. Usually four high-speed cameras shoot diagonally. This way, you can shoot different scenes and make a dynamic connection when editing.

Exterior backhand: the lens is in two positions parallel to the relationship line, facing the inside of the actor. Note: Symbols represent characters; The plane represents the front of the character. In the first case, the two cameras at the bottom of the triangle are behind the two main actors, close to the relationship line, and both of them are photographed.

Inside backhand: In this variant, the positions of two cameras are parallel to the relationship line, and an actor shoots on the outside. In the second scheme, the lens is between two actors, shooting outward from the triangle and close to the relationship line, but it does not represent the angle of the actors. In both cases, the actor is not facing the camera, although it is actually very close.
