science and technology . Technology led to the development of the editing idea development, led the development of the edit mode , edit mode to edit professional development , in turn, promote the development of technical and professional equipment . From the perspective of video editing , video editing has experienced linear editing and nonlinear editing .

Linear editing refers to a sequence according to the time needed to work from start to finish production methods . This editing method relies on a chronological record of the linearized vector material require editors to accurately grasp the contents of the lens , or once the error must be re-recorded , causing trouble and loss .

Non-linear editing is relatively linear editing purposes , it refers to the screen in any order without having to press the lens group then script the way in order to edit video programs . Nonlinear editing audio-visual signals can be stored and read a random basis , relying on the disk-based recording carrier. Of the material during the non-linear editing , can select any one of the lens or fragment edited without affecting the information that follows . Do not rest on its back or transcriptional reprogramming

Linear editing material can not freely accessible , often brought to the creative limitations, and the analog signal through multiple copies of the signal will be severely attenuated after use , resulting in lower quality sound and picture , is bound to affect the performance of film and television work force . The non-linear editing system of computer platform, with multimedia technology in the form of digital signals to store information , to avoid the appearance of signal attenuation simulation technology issues , and the creation of film and television works according to demand material to be arranged in any order , in operation more convenient and simple, greatly shorten the post-editing time and improve work efficiency.

Recalling the development of film and television history, seen the emergence of the concept of non-linear editing is not accidental , it is digital technology and video editing needs to develop to a certain stage of the inevitable outcome.

We know that TV movie creations into pre- and post- shoot editing, pre-shooting process is to obtain material , post-editing is the acquired material for finishing process, including editing, dubbing recording, effects processing , subtitles, titles credits packaging , etc., is a complex task, requiring the team division of labor, so the effectiveness of post-editing of film and television work relates to the whole success of post-editing can be said for half of the entire creation .

The current rapid development of digital technology , computer-based digital multimedia technology matures, digital non-linear editing showed a considerable advantage , more and more film and television production professionals and video editing enthusiasts of all ages .

Currently masses transmitted via satellite launch or closed TV channels can be received more than 30 , even more than a hundred , plus the introduction of different sections of each channel and content , viewers can choose to expand the range of content , form also more diverse. Faced with such a large amount of information , people have a lot of options , it can be said to win the audience is to win success. Keep holding the remote control in t
