What does "one card is multi-purpose" mean in animation? For example, how many shots does a card have? This is a card.

In fact, the card in the animation comes from the English cut, which means a shot. This shot is also a card animation, with at least one shot and at most countless shots. A card animation is not randomly divided, but is divided for the convenience of the original painter when making animation. It must meet the following conditions. If a card is composed of countless shots, then these shots must be at the same angle, and these shots must be coherent in time.
