The fifteen-minute program length is chosen here for convenience to illustrate cost examples. However, keep in mind that a viewer's attention span for general information is limited. A program longer than fifteen minutes requires exceptional presentation to assure the message will be absorbed by the viewer. Again, the number of videotaping locations is a critical cost factor. The most costly approach to a documentary program requires combining digital video effects and computer generated images to enhance program information transitions.
Commercial television is stiff competition.
It rarely makes mistakes and usually entertains viewers. In reviewing these cost ranges keep in mind that cost fluctuates independently in each category. In other words, less time spent in production on-location will allow more computer imaging or effects editing for the same amount of cost. Conversely, less effects editing or computer imaging will allow more on-location videotaping. An effective video training program can be produced to meet its objectives using simple to elaborate media support.
