Stop-motion animation is done by artists arranging puppets, clay figurines, paper cutouts, or other physical objects into a scene and taking a photo. The artists then manipulate the objects slightly, take another photo, and repeat that process many times, often 30 photos per second of film time.
The large quantity of still images is usually sequenced in order within specialized stop-motion animation software with capabilities designed for stop-motion animation to create a motion picture. That resulting animation is then edited like any other video, including adding music, voiceover, and sound and visual effects.
