The visual representation appears in all printed versions of the storyboard so that every member of the team can see the screen design. As each new object is added in the screen design, a corresponding set of data fields becomes available. This is why object orientation is desirable for storyboarding applications. Each page of the storyboard knows the exact number and content of media elements and it automatically inserts the appropriate fields when generating a printed script. Notice that in addition to entering a general description, writers can also include narration, video format, video type, duration, notes, actors, location, props, subject and also post-production information.
Writers simply create an object, then fill out the corresponding properties.
In field-based storyboards the source of narration is sometimes unclear. It could come from the video or it might come from an audio source, such as a .WAV file. It also focuses the writer on making conscious choices about media production requirements. This is very much needed when designing interactive courseware because a single interaction might contain dozens of media elements. Each time a new media object is added into the course storyboard, it automatically appears in a tool called Medialog.
