Tweening, short for “in-betweening,” is an essential animation technique employed to create the illusion of motion. It entails generating transitional frames that lie between two key images, effectively filling the gaps to make movements appear seamless. While this process can be executed manually, many animation software solutions have simplified and automated the task. Tweening plays a pivotal role in animation by ensuring that motions flow smoothly and appear natural. Without transitional frames, animations may appear choppy and disjointed. By incorporating tweening, animators can achieve a level of fluidity and realism that enhances the overall quality of their animations, captivating audiences with lifelike movements.
