Regarding tweened animation
Flash can create two types of tweened animation
* In the first one, called Motion tweening it is better to set position and size of objects in the keyframe of beginning of animation, and to set changing of position, size, color and transparency of objects or force them to rotate in the final one.
* In the second, called Shape tweening, in the key frame of beginning of animation one sets the initial shape of the object, and the final form in the keyframe of end of animation.
Flash interpolates the values of coordinates, size or shape of objects for all the intermediate frames, when creating animation.
Tweened animation is an effective way to create a smooth motion or change of objects without increasing the file size. Here, unlike frame-by-frame animation, Flash operates only with the differences of the subsequent frame from the previous one and does not render the whole object in every frame. For the same reasons, "Shape" for the complex objects increases the size of the final movie usually much more rather than "Motion".
