What is the term for the gradual transition of movement from one key frame to another?

1. Inbetweens

2. Tweens

3. Frames

4. Motion paths

The correct answer is: Inbetweens

The term for the gradual transition of movement from one key frame to another is known as inbetweens. In animation, key frames represent important points in the motion or transformation of a character or object. Inbetweening involves creating additional frames that fill in the gaps between these key frames to create a smooth motion flow. This process allows for the illusion of movement to be perceived seamlessly, enhancing the overall quality of the animation. The term "tweens" is often colloquially used in the same context as inbetweens, referring to the frames generated between two key frames, but it does not specifically capture the formal terminology used in traditional animation practices. "Frames" simply refers to individual images that make up an animation sequence, without implying the transitional aspect. "Motion paths" are specific lines or trajectories that an object follows in an animation but do not encompass the process of creating the frames in between key positions. Understanding these distinctions can deepen your grasp of animation techniques and terminology.
