What is animationWhat is animation
A sequence of images that create the illusion of movement when played in succession.
Here are some simple examples:
Slide 9 of 42
Why use animation?Why use animation?Easier to show somebody
how something works then to try and explain it.
Also animation: ◦Indicate movement
◦Illustrate change over time
◦Visualize three-dimensional objects
◦Attracts attention
Four Stroke Engine
Slide 10 of 42
How does animation work?How does animation work?Simulation of movement through a series of
pictures that have objects in slightly different positions
Each drawing is called a frame (a snapshot of what’s happening at a particular moment)
Required Frames Per Second FPS:◦ Movies on film 24 fps◦ TV 30 fps
9000 frames for five minute cartoon
◦ Computer animation 12 to15 fpsJerky if anything less
Slide 11 of 42
Sampling and Quantizing of Sampling and Quantizing of MotionMotionSince each frame is just an image
◦Each frame is sampled into a discrete samples and each sample becomes a pixel Sampling process Remember:
More samples means better quality (10 pixels by 10 pixels vs 200 pixels by 200 pixels)
More samples means bigger file sizes (10 pixels by 10 pixels vs 200 pixels by 200 pixels)
◦Each pixel gets assigned a colour, maybe just 2 colours(black and white1bit colour) or maybe 16 million colour (24 bit colour) Quantization process
Question: What else can we “Sample” with MOTION?
Slide 12 of 42
Frame Rate (Frames Per Frame Rate (Frames Per Second FPS)Second FPS)Frame Rate: indicates the
playback speed of the animation in frames per second◦Low frame rate appears choppy◦Question: BUT high frame rate can also
appear choppy, WHY? Answer: if the computer playing the
animation is not fast enough to process and display the frames.
Slide 13 of 42
2-D Animation 2-D Animation two types of 2-D animation:
◦Cel Animation (also called traditional animation, classical animation, hand-drawn animation, frame by frame animation)
◦Path Based AnimationBoth types still are made of frames:
◦The more frames per second, the more believable the movement will be.
◦The more frames per second, the bigger the final version of the movie file will be (more bytes)
Slide 14 of 42
Cel AnimationCel Animation
An animator must HAND draw every single frame!
To simplify, one background is drawn and then the item that will move is drawn on a clear sheet of plastic (a cel), one drawing for each frame.
When moving to the next scene, just change the background

Slide 15 of 42
Cel AnimationCel AnimationQuestion: What was the first full
length cel based animated movie? Hints:
◦Debuted in 1937◦Over 350,000 frames◦Over 1,500,000 pen and ink drawings◦Stars seven rather short guys and one p
asty brunetteOther examples:
◦Charlie Brown
Slide 16 of 42
Path Based AnimationPath Based AnimationPick:
◦a starting point for an object, (start frame)◦an ending point for an object (end frame)◦a path for the object to follow
And then the computer generated all the frames in between (called TWEENING), so that the artist doesn’t have to draw the intermediate frames (like the artist did in cel based animation)
Slide 17 of 42
Path Based AnimationPath Based AnimationQuestion: What name do we give to the
start frame and the end frame? (not the frames that are computer generated, rather the frames drawn by us?)
Question: Why is the act of generating the frames in between the first frame and the last frame called tweening?
Question: The path the object follows have to be a straight line, TRUE or FALSE?
Question: What software allows us to do path based animation?
Slide 18 of 42
Path Based Animation Path Based Animation SoftwareSoftwareThe software that generates the
frames has features such as:◦Looping◦Transition (Fade in and Fade out)◦Repetitions allows the user to pick
how many times the animation repeats◦Setting the Frames Per Second
Question: What does a bigger FPS imply? Larger file size More realistic motion
Slide 19 of 42
What can we do to change the What can we do to change the motion?motion?If the animation appears too slow, we can speed up the motion by:◦Reduce the number of frames (say pull
out every other frame)OR◦Increase the frame rate (go from 10fps
to 20fps)
Slide 20 of 42
Slowing down the motion by Slowing down the motion by adding more framesadding more framesAssume now that the motion is a bit too
fast, 2 ways to slow it down:◦ Way 1: Add more frames:
Keep the frame rate the same Increase the number of frames between the
keyframes to stretch out the animation◦ Way 2: Lower the frame rate (go from
20fps to 5fps) Keep the same number of frames as original but
stretches out movie◦ Original Clip has 5 frames, at 20 fps, so
finishes playing at 0.2 seconds, too fast! Way 1: still have 20 fps, but add in extra frames
between, now have 20 frames Way 2: holds frame on screen for 0.2 seconds, then
moves to frame 2, on screen for 0.2 second, etc….

Animated GIFSAnimated GIFS Question: What do you think the file size of an
animated gif is affected by:◦ Size of the gif (frame dimensions)◦ Number of colors ◦ Number of frames
Question: What do you think is the maximum number of colours you can have in an animated gif?
No Plug-ins Required: Animated GIFs require no plug-ins, and the authoring tools to create them are often free and easy to learn.
No Sound: If you need sound in addition to motion, you cannot use an animated GIF by itself. Instead, you may want to consider other animation alternatives, such as Flash, or even video
Plug-in: A program that permits web browser to access and execute files that the browser would not normally recognize. Flash uses Shockwave

FlashFlashA multimedia authoring and playback systemLaunched in 1996 by MacromediaAdobe bought it in 2005Flash became popular for its animated graphicsResponsible for much of the animations,
advertisements and video components found on today's Web sites
Flash is the industry's most advanced authoring environment for creating interactive websites, digital experiences and mobile content.
Some sample sites that do cool Flash animation:◦ http://www.zapiram.es ◦ http://www.pablogaribay.com
Slide 33 of 42
Why is Flash so popular?Why is Flash so popular? Interactive content rich with video, graphics, animation Import multimedia elements from other applications Support vector graphics:
◦ much more space efficient over bitmapped frames ◦ scale up with accurate detail no matter how large the
window is resized by the user. Flash Player is a free client application that works with
popular Web browsers to play the animation Adobe Flash Player is the standard for delivering high-
impact, rich Web content. Designs, animation, and application user interfaces are
deployed immediately across all browsers and platforms
Adobe worked out a deal to have the Flash player preinstalled on machines between the critical time period of 1998-2000 (before most people had broadband). This helped Flash over take Director in terms of popularity (users didn’t have to wait to install the player while surfing)

Essential Flash TerminologyEssential Flash Terminology
Question: What kind of tween would have been used in this Flash animation?
Stage: rectangular area where the visible motion will take place
Timeline: series of frames in a row and stacks of layers. Indicates key frames, regular frames and empty frames
Shape: basic shapes drawn with the shape tools, line tool or a single letter
Symbol: store in a library and can be reused. Changes to the library symbol will result in changes in all of the copies of this symbol currently on the stage.◦ Graphic: static graphic, can be used in other symbols◦ Button: interactive part of animation with user, responds
to mouse clicks and rollovers.◦ Movieclip: reusable piece of animation, can turn a simple
animation into a movieclip symbol and reuse it.

Essential Flash TerminologyEssential Flash TerminologyTweening: Creating the intermediate frames
based on the starting keyframe and ending keyframe. There are 3 types of tweens:
Motion Guide: lets you animation an object along a path that you draw yourself. Only works with symbols
Motion Tween Shape Tween
Classic Tween (from cs3)
Animates symbols only. Create the tween initially and then go to a frame and move the object and that frame becomes a keyframe
Works with non symbol shapes and vector graphics only
Animates symbols only. Need to manually create all keyframes and connect then with a tween
