Frame-by-frame animation is a technique in traditional animation where each frame of the animation is drawn individually. This is in contrast to tweening, where the computer generates the in-between frames. Frame-by-frame animation is more time-consuming, but it can produce more fluid and realistic animations.
Frame-by-frame animation is often used in high-quality animations, such as those seen in feature films and television shows. It is also used in video games and other digital media.
