persistence of Vision

Example: refers to the way our eyes retain images for a split second longer than they actually appear, making a series of quick flashes appear as one continuous picture.

Frame-by-Frame Animation

Example: what appears to be continuous motion is actually a series of many different frames. Each frame shows the same graphic with a tiny amount of position change to simulate motion.

Computer Assisted Animation

The computer is used to make the animation process quicker and easier. it usually involves 2-D images that can be hand-drawn and scanned into the computer or drawn directly into the computer using graphics tablets. The images are positioned into keyframes containing the most important movements.

Computer Generated Animation

All images, objects and animation are created on the computer. Tyically uses 3-D images. It adds two steps to the animation process. 1. modeling-process of creating a wireframe structure of the 3-D object and scenes. 2.Rendering-process of applying colors, textures, shadows, transparency, etc.

Path Animation

Examples: also called vector animation. An object follows a path which is a line, or vector, inserted by the animator.

morphing animation

a shortened term for metamorphosing. a technique in which one image is gradually turned into another.

Programming or scripting-Based Animation

Requires knowledge of a programming or scriping language. created by using scrupting languages such as Javascript.

Rollovers

Also called mouseovers. when the mouse is moved over an image it changes to a different image so quicklythat it looks as if the change has occurred in a single instant. they are created in scripting languages.

Stop Motion Animation

Processof manipulating real-world objects and photographing them one frame at a time. very popular method with the film industry until computer generated imagery became possible. now used mainly in clay animation.

Stage

the part of the animation program window where the animator's content is composed and manipilated

Frame

a single still image in a video animation.

Keyframe

show where the key (most important) actions accur

timeline

the part of the animation program window that organizes and controls an animation's content over time using layers and frames.

Library

used to store frequently used graphics, movie clips, and buttons.

playhead

the vertical red marker in the timeline that shows which frames are created between the keyframes that are needed to create that illusion of movement.

scrubbing

dragging the playhead across the timeline in order to preview an animation

tween(ing)

an animation process in which frames are created between the keyframes that are needed to create the illusion of movement.

compression

the process of reducing the space required to store data by efficiently encoding the content.

mp3

A standard format music files sent over the internet that compresses music.

WAV

the standard format for sound files on Windows-based computers

executable file

a program file that can caise an application to run on your computer when it is opened.

plug-in

a hardware or software application that adds a specific feature to a browser.

standalone player

a program that can work independently of a browser to play audio or video files.

bandwidth

the amount of data that can be transmitted over a network in a given amount of time.

streaming

a procedure for transmitting media files so they can start playing as soon as a computer begins receiving them rater than waiting for the complete files to download first.

streaming rate

the rate in frames per second at which the movie is downloaded

playback rate

the in frames per second at which the movie plays.
