Animated film has evolved from early techniques like frame-to-frame animation and stop motion photography. Frame-to-frame animation involved taking many photos over a few seconds to create the illusion of movement, while stop motion uses photography to make small changes between positions of objects. These early techniques aimed to bring drawings and inanimate objects to life. The document also discusses the 1964 Spanish cartoon "Telerín family" as an example of how animated films have changed over time in their shapes, colors, and purpose of announcing children's bedtimes.
