Frame-by-frame animation is a technique where each frame of the animation is created individually. This means that animators draw or create each image separately, which, when played in sequence, gives the illusion of movement. This method allows for detailed and expressive animations, as each frame can be carefully crafted. This technique is commonly used in traditional animation, such as Disney films, as well as in modern digital animation. It contrasts with other methods like computer-generated imagery (CGI), where models are manipulated rather than drawn frame by frame. Frame-by-frame animation requires significant time and effort but can produce stunning results.
