Animation is produced by the rapid display of consecutive still images
Minimum frame rate (humans) for smooth transitions is about 15 Hz.
For film/TV, 23 Hz to 30 Hz is normal.
For a smooth visual effect, higher frame rates may be necessary, and timing of frame displaying is important.
Types of animation:
Hand-drawn
Stop motion
Animatronics
Performance animation (mocap)
Virtual models
Effects
Early animation:
Early realanimation:
creating each frame of a real scene by hand = stop motion animation.
Example: King Kong (1933),
hybrid of animatronic and stop motion animation.
Timing
Timing is the speed of an action
Timing helps define an action (see example previous slide)
Proper timing is critical to make the audience understand an action: time the phases
(anticipation/action/reaction) so that the action is understood (not too short!) without losing attention (not too long!)
Timing defines weight of objects (including
characters)
Anticipation
Often anatomical necessity; no anticipation gives an unnatural movement
Prepares audience for an action -you know what is going to happen
Draws the attention action is not missed and can be faster
