4. Animations Showing discrete pictures one by one  give an illusion of continuous motion. Properties of an animation – Frame rate – Type of images – Image properties – Keyframes and tweening – Sound effects – Looping

5. Properties of an animation A. Frame Rate – Frame -- Still picture – # of frame / second (fps) –  frame rate, smoother animation – Range: 0.5 ~ 30 fps

6. Properties of an animation B. Type of Images – Vector-based or bitmapped Adjustable

7. Properties of an animation C. Image Properties – Bitmap graphics Depends on still images used, like image size, colour depth, transparency. – Vector-based Scalable, 24-bit colour Background (  transparency)

8. Properties of an animation D. Keyframes and Tweening – Keyframes Containing object to be animated. – Tweening The frame between 2 keyframes are filled up by s/w, like Flash ®.
