Non-linear editing system
The non-linear video editing (also German -English- mixed non-linear video editing, English:. Non-linear editing and NLE ) is a type of video editing.
In the non- linear editing, the raw material is transferred ( from various analog or digital video formats ) on the hard disk of a computer and processed there in any order ( = nonlinear).
Contrast to the linear section
The process can best be compared with the editing of a text in a word processing program: If you remove a paragraph of text, the following paragraph in the previous paragraph is approaching. If you write in between a set, overwriting not necessarily the next set, but the following text moves appropriately. Just as it behaves when non-linear video editing: If you add a scene, the subsequent scene moves accordingly on the end, and the film is longer. When older, linear video editing from tape to tape could replace a scene only against another equally long scene without having to copy the entire movie until then cut again.
Operation
Most non-linear editing systems are designed in their user interface so that in a single window you see all existing video and sound clips and in an additional window with a timeline view ( "Timeline" ) from these images and sounds can put together the finished film. In the timeline view, the effects are recognized - so opens when you double between two scenes mostly a dialog window where you can choose, for example a transition.
The fact that the picture and sound are stored as files on the hard drives of the computer easy it is to corrections of various kinds on the video to make ( for example, adjust brightness, correct color cast, etc.) occur without causing loss of quality. In the popular programs each is a set of effects available, with which the video can be changed. Also can be customized with a few simple steps to create different versions of a film by the timeline, so the playback order of the digitized material is copied and edited further.
History
As hard drives still expensive and the computers were not as powerful, could be used only in reduced quality ( off- Edit) by this method. The aim was to get a cut list with all the data that were needed for an automatic trimming in the conventional band-to- band operation. Meanwhile, the systems are so powerful and mass storage so cheap that to the finished TV show or the finished advert can be done any work inside the computer in the final quality. After a project is completed, the finished film either be copied to analog or digital video tapes, it can MPEG -2 files are created for the DVD production, or the material is copied directly to a transmission server and broadcast from there.
