What's the difference between flash traditional tween animation and tween shapes?

From easy to difficult, let's talk about the old version first:

Interpolation shape: the object must be scattered, need to have the first and last key frames, suitable for making some complex shape changes;

Traditional tweening: that is, the motion tweening in the old version also requires that the start key frame and the end key frame must be the same object (that is, the key frame can be directly inserted on the end key frame), and the objects are not scattered, such as graphic elements. It is also possible to draw scattered shapes and then combine them, but it must ensure the integrity, which is suitable for the position change and scaling of some objects and not suitable for deformation.

Tween animation: The new function only needs one key frame, and then click to create animation. But the object must be a component. After creation, you can extend the animation by inserting normal frames at appropriate positions; Or select a frame after creation and drag the position directly, which will automatically form a tail key frame, and you can continue to change some object properties of the tail key frame, such as transparency and brightness, which were not easy to set in previous versions.

So the appearance is no different from the traditional one, and the new tween option is different from the previous two in operation and function.
