Early animation used more than one image for each scene in order to create the illusion of movement. By rapidly displaying a sequence of slightly different images, known as frames, in quick succession, animators were able to make the characters or objects on screen appear to move smoothly. This technique, called "frame-by-frame animation" or "cel animation," allowed for the creation of lifelike and dynamic animations in the early days of the art form. Additionally, using multiple images per scene provided animators with the ability to convey a sense of depth, perspective, and action in their animations.
