Communications between media are very difficult. Similar goals are often approached in similar manners but use different technology and media specific techniques. The differences are emphasized and the similarities are obscured. Participants in one media focus only on the differences in technique and language and judge the work from another field as incomprehensible or inferior. This can be found in the disdain that animators have for illustrator's portfolios or film director's hostile reactions to screenplays by writers that contain any camera directions.
Multimedia is derived from and combines elements from prior media.
It helps to be able to draw upon and have an awareness of the arts that came before and can now be combined in new ways. Production has been streamlined. Physical production differences and constraints based on materials, media and physical distance have been minimized. However, since human beings change more slowly than technology, the differences in practice and terminology remain. Cooperative work and collaboration are being called for with much resistance.
