Computer Studies Lesson No.9 multimedia programs

We expect multimedia programs to able to:

·         Import multiple types of electronic media files, including text, images, animated graphics and sound and video files

·         Create transition and animation effects and interactivity(such as hyperlinks, hotspots, image maps, buttons and rollover effects)

 Multimedia authoring programs

     A multimedia authoring program (‘ or authoring tools’), such as Adobe Flash, can produce multimedia ‘movie files’ most often intended for viewing with web browser.

     A web browser need a multimedia player extension(or ‘plug-in’) to play these

     Some programs, such as Flash, are intended to have the interactivity of their output enhanced by programming in scripting language, while others are intended for non-programmers. 

Features of multimedia authoring programs include:

Ø  ‘frames’ that hold successive appearances and position of graphical objects in animations

Ø  Layers to enable ‘INBETWEENING’ of graphical objects without  interference from other graphical objects

Ø  Creation of multimedia movie files for web pages

Ø  Creation of relatively powerful web applications, such as Rich Internet Applications(RIAs)

Ø  Features of multimedia authoring programs include:

Ø  Creation of computer-assisted learning(CAL) activities

Ø  A scripting language to extend interactivity

Ø  Export of content as a website, presentation interactive CD-ROM or computer program file

  Inbetweening
Inbetweening frames between two vector graphics of different positions, shapes or colors, to give an illusion of smooth change or movement.
