How did the scene of the conversation between the two people in the movie change? Should he shoot with multiple cameras at the same time, or should he only use one camera to shoot and then edit?

In a movie, the scene where two people were talking could usually be switched by multiple cameras shooting at the same time. During the shooting process, the director could switch and adjust according to the needs, so that different scenes and images could be switched between different cameras to achieve a smoother and more natural lens switching effect. Of course, in practice, because shooting required a lot of time and resources, many movies usually used a single camera to shoot and then through post-editing to achieve the scene switching. During the editing process, the director could combine different scenes as needed to form a complete story and scene switching. This method could save time and resources while making the film production more efficient and complete.
