Definitions for "Non-linear editing"
Editing video on computer hard disk. Disks are non-linear format - they store the data in a random order and allow virtual instant access to any part of it Non-linear editing may be carried out with a home computer, such as a Mac or PC. The video from the camcorder passes through a digitiser and is stored on the computer's hard disk (a lot of hard disk space is required gigabytes, rather than megabytes). Appropriate software allows you to review shots, create an edit decision list, add titles and special effects, then preview the edited movie, before copying it to tape.
The computer-assisted editing of video without the need to assemble it in linear sequence. The video-editing equivalent of word processing.
Frequently this means a system of editing on a desktop computer that uses digitized video which is stored on a series of hard drives. The editing software allows the operator to make any number of editing decisions, and allows them to change those edits, even durations of individual pieces, in a non-destructive fashion. Any changes are merely rippled throughout the project, as individual clips slip and slide to compensate for the changes. This is contrasted with traditional editing which is linear, where editing started at the beginning of the program, with material added sequentially to the project, with the end eventually reached at the end of the session. Any changes in duration in the middle of a project required reassembling the subsequent edits to the end.
