what type of animation is nightmare before christmas

Nightmare Before Christmas is a stop-motion animated film that was created using a process called stop-motion animation. In this type of animation, real-world objects or puppets are used and then moved incrementally to create the illusion of movement. Each individual frame of the film is created by adjusting the position of the characters or objects and then capturing a photograph of the scene. This process is repeated thousands of times to create a fluid and seamless motion picture.
