Rotoscoping is a technique used in animation and visual effects where artists trace over live-action footage frame by frame. This process allows for the creation of realistic movements and can be used to integrate animated elements with real-world scenes. It is commonly employed in movies, video games, and commercials to enhance visual storytelling. Originally developed in the early 20th century, rotoscoping has evolved with technology. Today, software tools like Adobe After Effects and Toon Boom streamline the process, making it easier for animators to achieve detailed and fluid animations.
