Video is a true technical revolution. In a few short years it has totally transformed such diverse fields as home entertainment and commercial news production. It was not that long ago that we were taking 8-mm home movies with a 50-foot roll of film. Processing took a week. Poor lighting produced an underexposed picture, which was lost forever. Editing was cumbersome and the possibilities were very limited. With luck, the movie ran for a few minutes.
The definition of Video has broadened over the years, and now covers classic Video, high definition Video and computer based Video and graphics – anything that can be displayed on a screen and viewed.
In Video, you need only to a push button. There is nothing to develop, wash, or wait for, and results are immediate. The remarkable versatility of Video magnetic tape or inexpensive recordable DVDs, its low cost and ease of use are the major reasons for its success.
