Before tweening the color of groups or text, convert the objects into symbols. Before animating individual characters in a block of text separately, break each character into a separate text block by choosing Modify > Break Apart and then placing each character on its own layer.
If you create a classic tween and then change the number of frames between the two keyframes—or move the group or symbol in either keyframe—Flash automatically tweens the frames again.
To create a classic tween, create an empty keyframe in the layer where you want the animation to begin. Add content to this keyframe by drawing on the Stage or by dragging an instance of a symbol from the Library panel.
Select the location to the right of the first keyframe on the same layer in the Timeline and choose Insert > Timeline > Keyframe to specify where the animation will end. Modify the content of the ending keyframe and then right-click or Control-click any frame between the two keyframes and choose Create Classic Tween from the context menu that appears.
Note: To create a tween, you must place only one object on the layer.
To tween the color of elements other than instances or text blocks, use shape tweening.
Apply easing to classic tweens to produce a more realistic sense of motion. Enter the easing value in the Property inspector or use the Custom Ease In/Ease Out dialog box to precisely control the speed of the classic tween.
