Freeze-frame is one of the techniques used in focal plane. It is the instantaneous "condensation" of action. The specific production method is to select a certain frame in the shot and print it repeatedly by the printer to extend the stopped frame to the required length. According to the needs of lens editing, the freeze-frame processing can be from moving (animation surface) to static (freeze-frame picture), and also from static (freeze-frame picture) to moving (animation surface); At the end of the film, some people use freeze-frame to indicate the end of the story, or use it as a topic to leave a aftertaste for the audience.
