Analogue
Analogue editing is the cutting together of pieces of celluloid. Traditionally films are made up images printed on to acetate negatives. These are then spliced together to form a reel a of film. These are then fed through a projector at a constant speed of 24 frames a second which makes the picture appear to be moving. this is known as as analogue.The first Moviola.
Before the widespread use of non linear editing systems, the initial editing of all films was done with a positive copy of the film negative called a film work print (cutting copy in UK) by physically cutting and pasting together pieces of film, using a splicer and threading the film on a machine with a viewer such as Moviola.
Video Editing is the process of editing segments of motion video production footage, special affects and sound recordings in the post-production process. Before digital technologies became available magnetic tapes were used to store information- these are known as video tapes. Most video editing has been superseded by digital editing which is faster and cheaper.
Digital Editing.
Digital media is a form of electronic media where data are stored in digital (as opposed to analogue) form. Digital editing is the use of computers to order and manipulate this digital data. Digital cinema uses bits and bytes (string of 1s and 0s) to record, transmit and reply images, instead of chemicals on film. The whole process is electronic so there is no printing or splicing involved.
Non-Linear Editing.
In digital video editing, non-linear editing is a method that allows you to access any frame in a digital video clip regardless of sequence in the clip. The freedom to access any frame, and use a cut and paste method, similar to the ease of cutting and pasting text in a word processor and allows you to easily include fades, transitions, and other effects that cannot be achieved with linear editing.
