TMD2063 | Digital Animation - Chapter 2

  1. 1. ANIMATION TECHNIQUESTwo types animation techniques: Conventional Animation Digital Animation
  2. 2. CONVENTIONAL ANIMATION5 types of conventional animation: Drawn animation Cut-out animation Stop motion animation Rotoscoping Limited animation
  3. 3. DRAWN ANIMATIONProduced by a series of drawn images that been stacked together sequentially.Each drawing is differing slightly from the one before and after.To produce a complex animation (for example, animated movie) requires several thousands of drawings that will be presented on screen one by one at a fast rate.
  4. 4. DRAWN ANIMATIONSeries of drawn images will be traced onto transparent cels (celluloid acetate sheets) to create fine lines before coloring process begins.Advantages : it can produce an attractive and controllable effect.Disadvantages : it is time consuming and requires a lot of work.
  5. 5. CUT-OUT ANIMATION a graphic symbol for the leg, below.
  6. 6. CUT-OUT ANIMATIONKnown as collage animation/ silhoutte animationCut-out animation involves moving cut-out shapes in small stepsTaking a picture at each stage, this is a lot less work than having to draw every single frame of the animation.
  7. 7. CUT-OUT ANIMATIONAdvantages: easy to create and requires less cost and equipmentDisadvantages: animation effect is not realistic and not attractiveExample: Angela Anaconda, South Park & Wonderpets
  8. 8. STOP-MOTION ANIMATIONKnown as model animation and claymotion.Process of recording the manual movement or three dimensional object to create animation effect.Usually clay is used to create puppet.Object moved then recorded.The whole recording will be played to produced animation effect.Example: Chicken Run, Bob The Builder and Wallace And Gromit.
  9. 9. ROTOSCOPINGThe process of tracking contours in a video sequences.
  10. 10. ROTOSCOPINGRotoscoping refers to the process of tracing the action, character and so on from video or real film.Advantages: It requires video or film as a platform of creating the animation. It produces a realistic effect to the animation.Disadvantages: This technique is used to produce a complex movement that is hard to create by ordinary technique.
  11. 11. LIMITED ANIMATIONProcess of making animated cartoons that does not follow a realistic approach.Creates an image that uses abstract art, symbolism, and limited movement to create the same effect, but at a much lower production cost.Allows animation cels to be duplicated, resulting in a lower number of separate frames per second (normal conventional animation use 24-30 fps, limited animation use 12 fps)
  12. 12. DIGITAL ANIMATION4 types of digital animation: Cel-based animation  Known as Frame Animation
  13. 13. DIGITAL ANIMATION Path-Based animation  Process of animating object over line or path
  14. 14. DIGITAL ANIMATIONObject animation Changing on specifications or characteristic of object.  color ,  size,  shape,  LightingScene transition  Use fade in and fade out
  15. 15. ANIMATION TERMINOLOGIES5 elements in animation terminologies : Keyframes Tweening Onion skinning Frame rate Aspect ratio
  16. 16. KEYFRAMES It is the main frame in an animated sequence that represents major change to object. Act as a reference for other frames in animated sequence.
  17. 17. TWEENING Refers to the process of creating object between keyframes to generate animated sequence. Animator creates object in the first and last keyframe only. While frames between keyframes (inbetweening) will be generated automatically by software.
  18. 18. ONION SKINNINGTechnique used in creating object and editing movies to see several frames at once.
  19. 19. FRAME RATE The measurement of how quick an imaging device produces consecutive frames when presenting animation. Measured as fps (frame per second). Standard fps is 12fps
  20. 20. ASPECT RATIO Refers to the distribution of pixel on screen for production process. It measures based on the number of pixel on screen; width x height. In general, computer screen aspect ratio measurements are 640 x 480, 800 x 600, 1024 x 768 and so on.
  21. 21. ASPECT RATIO By default, aspect ratio in Flash is 550 x 400, suitable for viewing through computer and web. For animation presentation through video screen, this aspect ratio should be changed to fit with the standard aspect ratio for video screen. Two aspects ratio for video screen;  PAL (768 x 576) and  NTSC (720 x 540).
