It gives you more ways to interpolate between values. In brief, it generates new keyframes between existing keyframes. It allows you to easily animate pictures, videos, logos, and text without heavy editing. Tweener allows you to create very smooth animations using Track Motion and Pan/Crop properties. Sometimes, you have to create multiple keyframes, if you want to generate a reasonably-smooth animation. You simply specify the start and end keyframes and Vegas dynamically generates the frames in-between to make a transition between states. In Sony Vegas, objects (solids, images, video clips, text titles etc.) can be animated or morphed between one state and the next over a period of time.

A tween can be defined as an interpolation from one position to another. It is about creating frames between keyframes. Tweening is the process of generating intermediate frames between two images to give the appearance that the first image evolves smoothly into the second image.
