What is tweening?

Tweening, short for in-betweening, is a technique used in animation and computer graphics to create smooth transitions between keyframes. Keyframes are the main frames that define the starting and ending points of an animation sequence, while tweens are the frames that fill in the motion between those keyframes.

There are two main types of tweening: linear and curved. In linear tweening, the motion between keyframes is evenly spaced and moves at a consistent rate. In curved tweening, the motion follows a curved path, which can create more realistic and fluid animations.

Tweening is commonly used in 2D and 3D animation, as well as in motion graphics, video editing, and user interface design. It helps to create more dynamic and visually appealing animations by reducing the amount of manual frame-by-frame animation required.

Popular software tools like Adobe After Effects, Adobe Animate, and Blender have built-in tweening features that allow animators to easily create smooth transitions between keyframes.
