Tweening (PSE 15+)

You don't always need to create and modify each frame manually. Some of the tasks can be done automatically.

For example, an object's movement or a shape's transformation can be animated like follows.

1. Create two frames containing the initial and final states.

This may be done
- by showing different layers for each frame
- or by repositioning the same layer(s)
(fig. 1/1 --> fig. 1/2).

2. In the "Frames" panel of the "Animation" dialog, select the both -- initial and final -- frames (fig. 2).

3. Run "Tween" command (fig. 3).

4. In the dialog that opens, define how many frames should be inserted between the initial and final frames (fig. 4).

5. Optionally, you may also define which layer parameters should be "tweened": position, opacity, and/or effects (fig. 5).

PSE automatically inserts the intermediate frames and sets the layer properties for each one.
