Video Editing Process
Film editing evolved from the process of physically cutting and taping together pieces of film, using a viewer such as a Moviola or Steenbeck to look at the results.All initial editing is done with a positive copy of the negative called a workprint. This allows the editor to do as much experimenting as he or she wishes, without the risk of damaging the original.
When the workprint has been cut to a satisfactory state, it is then used to make a negative cutting list. The negative cutter refers to this list while processing the negative, splitting the shots into A and B rolls, which are then optically printed to produce the final film print.
Since the film was physically cut and pasted, a 'nonlinear' style of editing evolved. At the workprint stage, strips of film could be placed in any order. This approach is generally considered superior to the strictly linear approach that was necessary in video editing through the 1970s. A video 'cut' is really the copying of scenes from various camera tapes onto a master. Before the development of powerful computer systems that could store large amounts of visual data for transfer, it was necessary to make the transfer in strictly linear order. Trying to insert a shot between two shots already on the master tape would create noise, etc. A system such as Avid allows the creation of a workprint. (more)
