Offline editing is part of the post-production process of filmmaking and television production in which raw footage is copied and edited, without affecting the camera original film stock or video tape.
Once the project has been completely offline edited, the original media will be assembled in the online editing stage.
The term offline originated in the computing and telecommunications industries, meaning “not under the direct control of another device” (automation).
Modern offline video editing is conducted in a non-linear editing (NLE) suite.
The digital revolution has made the offline editing workflow process immeasurably quicker, as practitioners moved from time-consuming (video tape to tape) linear video editing online editing suites, to computer hardware and video editing software such as Adobe Premiere, Final Cut Pro, Avid, Sony Vegas and Light works. Typically, all the original footage (often tens or hundreds of hours) is digitized into the suite at a low resolution. The editor and director are then free to work with all the options to create the final cut.
