A picture frame is a stationary object, and a static picture frame is used to express the movement, which is usually called "the internal movement of the picture".

(2) the external movement of the picture

If the subject is static, using a moving picture frame to represent a static object is usually called "out-of-painting movement".

(C) the comprehensive movement inside and outside painting

If the subject is moving and the picture frame is also moving, that is, the focal length, optical axis and camera position of the camera move in one direction or at the same time, then this movement is often called "integrated movement inside and outside the picture"
