Sub-lens is divided into early conception and later editing in movie and TV animation. So it is very important to split the camera. Split shot can control the rhythm and style of movie and TV animation. The sub-lens in movie and TV animation is different from the sub-lens in TV movie. The sub-lens in movie and TV animation can control all elements and is the "instruction file" of movie and TV animation. Any idea can be presented in movie and TV animation. You can see the expected effect in the early stage of production, and the split-shot art makes movie animation more concrete in the middle stage of production. When the various tasks of the sub-mirror were finalized, the staff took it as a reference to restore the work. It is precisely because of this that sub-lens plays an important role in movie and TV animation.
