4.1 The Traditional Route

On our journey through the complexities of video compression, we now look at movie film. Film has been around for a while. It was the first kind of moving image to be recorded, so we could think of film as a classic or traditional format.

TV has been with us for many years, too, but film has been around much longer. Most major studios have been in existence for 80 years or more, and the technology existed for some time even before Hollywood became properly established.
