Uses of Computer Animation

-Advertising -Used to catch attention -Entertainment -Films, computer games and virtual reality. -Selling-showcasing products or services. -Teaching-illustrating concepts or processes -Training-simulating events or demonstrating techniques.

Persistence Of Vison

-In the early 1800's, the phenomenon known as persistence of vision gave mankind the first glimpse into the modern world of animation. -Persistence of vision 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 EX: Using a flip book, you can see the persistence of vision effect in action. If you have a different sequential drawing on each page of the flip book and you flip through the pages rapidly, the drawings appear to move.

Stop Motion Animation

-Process of 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.

Frame by Frame animation

-Rapidly displaying images, or frames, in a sequence to create the optical illusion of movement.Digital animation is based on the frame by frame animation process. -The quality of frame-based animation depends on the frame rate.Frame Rate = Frames per Second -FPS= Smoother Action -The more frames per second, the smoother the motion appears.

Programming or script based animation

-Requires knowledge of a programming or scripting language. :Example: Rollover or Mouseover. :When the mouse is moved over an image, it changes to a different image so quickly that it looks as if the change has occurred in a single instant. :Created by using scripting languages such as Javascript. Rollovers are extremely important for navigation buttons on user interface designs. EX: -Web pages -CBT programs -Kiosks -CD-ROM Training-Games -CDs and DVDs

Animation

-The rapid display of a sequence of images of 2-D or 3-D artwork or model positions in order to create an illusion of movement. -Relies on persistence of vision to create the illusion of movement.

Morphing animation

-The term morphing comes from the word metamorphosis, which is the transformation of one thing into another. The beginning image is inserted. -The ending image is inserted. -The computer performs the tweening to generate a sequence of images, each of which is slightly different from the one it follows to gradually morph the two objects. -For example, a photograph or object might gradually morph into a different photograph or object

Frames

:Frames hold the content that the movie displays or plays at that point in time :The number of frames determines the length of the animation. :The higher the number of frames, the longer the animation.

Postproduction

All events between production and creating the final version of the video.

Trimming Clips and Creating Sequences (post production)

Clips: Small segments of a larger video. Trim: To hide parts of a file or clip without deleting them from the original source. Sequence: A variety of wide, medium, and tight video shots edited together to compress time, add interest, and help the viewer movie efficiently through a story. Timeline: Shows the components of the movie such as photos, video, audio clips and titles in the order and timing that they will appear in movie.

Apply Effects(post production)

Transitions: The visual movements as one picture, video clip, or title changes to another. -Transitions are not applied directly to the clips, but are used to move from one to another. (Common: Cross Dissolve) -Video Effects: Enable you to add special effects to your movie. An example would be adding a Film Age video effect to make your movie clip to look like that of an old time movie or making the video black and white.

Playhead

Vertical red marker in the timeline that shows which frame is the current frame.

Layers

Timeline is divided into layers to help organize content and allow the different layers to be edited separately. :Sound would be on a separate layer. :Text would be on a separate layer. :A motion path would be on a separate layer.

Frames per second(FPS)

The number of frames that appear in one second of the animation. EX:If the animation program creates movies at 12 fps (frames per second) by default, inserting a keyframe and change once every 12 frames results in a change in action for every second. A project with 60 frames results in a 5-second movie.

timeline

The part of the animation program window that organizes and controls an animation's content over time using layers and frames. In video-editing software, where source clips, transitions, and audio files are arranged to create the video.

Exporting(post production)

Common Video File Types .avi (Audio Video Interleave) -Created by Microsoft; Uses less compression than MOV or MPEG; Supported by almost all computers using Windows .mov (Apple Movie) -Developed by Apple Computer; Cross-Platform; Opens with Apple QuickTime .mp4 (MPEG-4) -Developed by Moving Pictures Expert Group; Compresses well; Commonly used for the Internet .flv (Flash Video) -Developed by Adobe Systems; Commonly used to deliver video over the Internet by using Flash Player; Used by YouTube, Hulu, VEVO, etc..

Regular Frames

Contain one image or frame.

Scrubbing

Dragging the playhead across the timeline in order to preview the animation.

Capturing Video(post production)

Importing video from the original recording device.

Motion Guide Layers

Layer on which a motion path is drawn. -Objects on different layers can be linked to the motion layer so they will follow the motion path. _Once linked, they become "guided layers" :Multiple objects can be linked to one motion layer. :Text layers can also be linked to a motion layer

Stage

Part of a program where the animation is composed and controlled.

Path Based animation

Path Based Animation -Also called vector animation. -An object follows a path which is a line, or vector, inserted by the animator. -A motion path can include curves, loops, and angles. --The computer calculates the correct position of the object as it moves along the path and generates the frames to create the animation. -Vector graphics or animated gifs can be used to create animations with very small file sizes. - The small file sizes make this type of animation very popular on the Web. -Many of the banner ads and embedded animations viewed on web sites use this technology because it loads so quickly and is easy to use.

Adding Titles and Graphics(post production)

Rolling credit-include cast and credit for source

Keyframes

Shows where the key (most important) actions occur.

Adding/editing sound(post production)

Soundtracks or sound effects: Additional audio added as background or to enhance specific points in the video. Narration: Audio of one or more people that has been recorded to enhance or assist in telling the story for your video.

library

Stores frequently used graphics, movie clips, and buttons.

Production

The actual shooting/recording of the video. -framing shots/field of view :shots type:wide.medium,tight :panning and zooming :Audio(microphone choice) : lighting(natural and artificial)

Preproduction

The event that took place before the actual shooting of the video. -idea generating(brainstorm) -Script writing(writing text for your movie) -Story Boarding(A sequence of drawings, directions and sometimes with dialogue that represented the plan shots for movie) -Casting(Find people that would play the role of the video) -Scouting locations(looks and feel,associated cost,lighting,permission,logistics:power,distance, and parking)
