Linear & Non-Linear Editing

May 10, 2012

Linear and non-linear are both valuable forms of editing. Non-linear was a revolutionary step in the editing world as it is cheaper, faster and more efficient.

Linear editing is a long and demanding job. It is mainly used when using video tape as that cannot physically be cut up and returned together in the order which the film is. The editor must edit the film from start to finish. This means if he has three tapes of film he must go through these all to decipher what has to go where and then go on to record this to a master tape. However, editors can “splice” the film together. This is done by actually cutting the tape up and putting it back together whichever way was needed, which is how traditional film was edited. Again, this was long and limited but also left a lot of room for error. In linear editing, if the editor wanted to replace a clip, he would have to film over the clip he wanted to replace and hope that both were the same size otherwise he would be left with the ending of the previous clip on the master tap or if the new clip is too long then it will cut into the next scene as well both these examples slightly corrupting the image quality.

Non-linear is the more common approach to editing. It has a lot more freedom and benefits in comparison to linear editing. The editor can simply cut, copy and paste the clips that he wants to where he needs it effortlessly. This saves time and money. He can add transitions and effects to make the editing more realistic and comfortable to watch as well as change his mind as often as he likes in real time, there is no need to rerecord anything and he will know that if he replaces anything it will fit perfectly into a space. Also the clips can be saved onto a timeline where they can be trimmed to size and as previously said; transitions and effects can easily be added. Furthermore, non-linear editing is done digitally. This means that film can be saved and accessed easily from a hard drive as well as be saved more than once for assurance. It is easy to export the finalised film to DVD or the web straight away.
