  2. Multimedia Authoring and Tools • 2.1 Multimedia Authoring • 2.2 Some Useful Editing and Authoring Tools • 2.3 VRML(Not Covered) • 2.4 Further Exploration

  3. 2.1 Multimedia Authoring • Multimedia authoring: creation of multimedia productions, sometimes called "movies" or "presentations". • we are mostly interested in interactive applications. • Adobe Photoshop, Adobe Premiere. • In this section, we take a look at: • Multimedia Authoring Metaphors(paradigms) • Multimedia Production • Multimedia Presentation • Automatic Authoring

  4. Multimedia Authoring Metaphors 1-Scripting Language Metaphor: use a special language to enable interactivity. 2-Slide Show Metaphor: A linear presentation by default, although tools exist to perform jumps in slide shows. 3-Hierarchical Metaphor: User‐controllable elements are organized into a tree structure 4-Iconic/Flow‐control Metaphor: Graphical icons are available in a toolbox, and authoring proceeds by creating a flow chart with icons attached (Fig. 2.1):

  5. Multimedia Authoring Metaphors

  6. Multimedia Authoring Metaphors 5 - Frames Metaphor: Like Iconic/Flow‐control Metaphor; however links between icons are more conceptual, rather than representing the actual flow of the program

  7. Multimedia Authoring Metaphors 6- Card/Scripting Metaphor: Uses a simple index‐card structure —easy route to producing applications that use hypertext or hypermedia; used in schools.

  8. Multimedia Presentation • Graphics Styles: Human visual dynamics impact how presentations must be constructed. • a) Color principles and guidelines: A general hint is to not use too many colors, as this can be distracting. • b) Fonts: For effective visual communication in a presentation, it is best to use large fonts (i.e., 18 to 36 points), and no more than 6 to 8 lines per screen.

  9. A color contrast program: If the text color is some triple (R,G,B), a legible color for the background is that color subtracted from the maximum: (R, G, B) => (max− R, max − G, max − B) • Some color combinations are more pleasing than others; e.g., • a pink background and forest green foreground, • a green background and mauveبنفش foreground.

  10. Video Transitions • Video transitions: to signal "scene changes". • Many different types of transitions: • Cut • Wipe • Dissolve • Fade in and Fade Out • …
