  1. Multimedia Authoring Tools Lecture 13 By RaziaNisarNoorani

  2. Multimedia Authoring Tools • Multimedia authoring tools provide the important framework you need for organizing and editing the elements of multimedia like graphics, sounds, animations and video clips. • Authoring tools are used for designing interactivity and the user interface, for presentation your project on screen and assembling multimedia elements into a single cohesive project.

  3. Multimedia Authoring Tools • Authoring software provides an integrated environment for binding together the content and functions of your project. • Authoring systems typically include the ability to create, edit and import specific types of data; assemble raw data into a playback sequence or cue sheet and provide structured method or language for responding to user input.

  4. Types of Authoring Tools • Card or page based tools • Icon based, event driven tools • Time based tools

  5. Card or page based tools • In these authoring systems, elements are organized as pages of a book or a stack of cards. • These tools are best used when the bulk of your content consists of elements that can be viewed individually, like the pages of a book or cards in a card file. • The authoring system lets you link these pages or cards into organized sequences. • You can jump, on command, to any page you wish in the structured navigation pattern. • It allows you to play sound elements and launch animations and digital video.

  6. Card or page based tools • Advantages • Easy to understand metaphore • 1 screen= 1 card= 1 page • Ease of use • Provide templates • Short development time • Disadvantages • Some run only on one platform • Tools not as powerful as equiv stand alones • Software • Hypercard

  8. Icon based, event driven tools • Icon or event driven tool is the simplest and easiest authoring system. • Simple branching is the ability to go to another section of multimedia production. • Multimedia elements and interaction cues are organized as objects in a flow chart. • Icon- base, event-driven tools simplify the organization of your project and typically display flow diagrams of activities along branching paths. • In complicate structures, this charting is particularly useful during development. • Flowchart can be built by dragging appropriate icons from library and then adding the contents.

  9. Icon based, event driven tools • Advantages • Clear structure • Easy editing and updating • Disadvantages • Difficult to learn • Expensive • Softwares • Authorware • IconAuthor

  10. Icon based, event driven tools

  11. Time based tools • In these authoring systems, elements and events are organized along a timeline, with resolutions as high or higher than 1/30 second. • Time based tools are best to use when you have a message with a beginning and an end. • Sequentially organized graphic frames are played back at a speed that you can set. • Other elements are triggered back at a given time or location in the sequence of events. The more powerful time based tools let you program jumps to any location in a sequence, thereby adding navigation and interactive control.

  12. Time based tools • Softwares • Macromedia Director • Flash

  13. Macromedia Director • A multimedia database, ‘cast’, contains still images, sound files, text , shapes, script, movies and other director files. • Score is a sequencer for displaying, animating and playing Cast members. • Lingo is an object oriented scripting language that enables interactivety and programmed control.

  14. Macromedia Director • Advantages • Good for creating animation. • Branching, user control interactivity • Disadvantages • Expensive • Steep learning curve for advance features.

  15. Macromedia Flash • Flash is used for delivering rich multimedia contents to the web. • It allows the creation of of simples static HTML with the flash player plug-in.

  16. Macromedia Flash • Advantages • Easy to put animated and interactive movies. • Interactive menus • Disadvantages • Increase in file size • Music and sound files embedded in flash movies increase file size and increase the file size.

  17. Top seven Authoring Tools • Adobe Captivate • Articulate Presenter • Articulate Engage • Adobe Connect • TechSmith Camtasia • Adobe Presenter • Harbinger Raptivity

  18. Categories • Best Use: Can you use the product to create applications of a certain type; e.g. software simulations? • Interface: Do you use the product online or in PowerPoint? Does it use wizards or a stage? • Can Insert: What media formats can you put in your eLearning by using the tool? • Platforms: Does the application run in Windows, on a Mac, or online? • Publish to: To which formats can you publish your eLearning? • Cost: What are the initial and update costs of the product?
