The term "tweening" is derived from "in
betweening," the traditional animation term used
to describe this process. Tweening significantly
reduces the time required to create animation
effects such as fading in or fading out, or moving
an element across a frame. You can edit tweened
frames individually after you create them.
Using tweening to animate warped text: Specify different
warping effects in two frames of the animation, then use the
Tween command to generate the intermediate frames.
To create frames using tweening:
To apply tweening to a specific layer, select it in
1
the Layers palette.
2 Select a single frame or multiple contiguous
frames.
If you select a single frame, you choose whether to
tween the frame with the previous frame or the
next frame. If you select two contiguous frames,
new frames are added between the frames. If you
select more than two frames, existing frames
between the first and last selected frames are
altered by the tweening operation. If you select the
first and last frames in an animation, these frames
are treated as contiguous, and tweened frames
are added after the last frame. (This tweening
method is useful when the animation is set to loop
multiple times.)
Note: You cannot select discontiguous frames
for tweening.

Effects to vary the parameter settings of layer
•
effects evenly between the beginning and
ending frames.
If you selected a single frame in step 2, choose
6
where to add frames from the Tween With menu:
Next Frame to add frames between the selected
•
frame and the following frame.
