Analogue Editing
Analogue editing is the cutting together of pieces of celluloid film. Traditionaly images are printed on to acetate negatives to make films. These are "Spliced" together to form a reel of film which are then fed through a projector at a constant speed of 24 frames a second. This makes the images appear to be moving.
In 1924, Iwan Serrurier invented The Moviola which was the first device that allowed a film editor to view a film while they were editing it. It was the first machine used for feature length motion picture editing. Magnetic tapes were used to store information before digital technologies became available. These are known as video tapes. Video editing is the process of editing segments of these tapes and it is done using a devise that mechanically puts pieces of video tape together. The films are edited using something called 'Linear Editing,' which means they have to be editied in the correct order.
An advantage of Analogue editing is that the image on screen will be of very high quality. However, Analogue editing is very time consuming and celluloid is expensive.
Digital Editing
Digital media is a form of electronic media where data is stored in digital form. Digital editing is the use of computers to order and manipulate this digital data. There are many different editing programmes. These include Adobe Premiere, Avid and Final Cut Pro.
Digital film making uses strings of 1's and 0's to record, transmit and reply images instead of using chemicals on film. The whole process is electronic so there is no printing or "Splicing" involved. Digital editing soon over took video editing as it is much more quicker and cheaper than Analogue editing. The biggest advantage is that you can edit digitally in any order. This is known as 'Non-Linear' editing. You can edit a sequence from the end of a film before you have started editing the first scene. The process uses electronic files so it makes it as easy as cutting and pasting text in a word document.
