Avid offline editor code#
A time code reader device translated this signal into hours, minutes, seconds and frames, originally displayed on a Nixie tube display, and later with LED readouts. Time code introduced frame precision, by recording a machine readable signal on an audio channel. An announcer reciting the seconds was recorded onto an audio channel on the tape. Early attempts to rectify this were primitive to say the least. Only video, audio, and a control pulse were recorded.
Whereas film negative had numbers printed optically along the side of the film, so that every frame could be identified exactly, video tape had no such system. The first was the invention of time code. Three developments of the late sixties and early seventies revolutionized video editing, and made it possible for television to have its own version of the film workprint/conform process. Even such fast-paced shows as Rowan & Martin's Laugh-In continued to use the razor blade technique. This was the way things were for television shows shot on tape for the first 15 years. This technique of re-recording from source to edit master came to be known as linear video editing. Beyond not being very precise, recorders of this era cost much more than a house, making this process an expensive use of the machines. Each machine was rolled forward simultaneously, and a punch in recording, similar to punch in / out of early audio multitrack recordings was made at the appropriate moment. The original tapes were pre-rolled, manually cued to a few seconds prior to the start of a shot on the player, while the recorder was set to record. The second option for video editing was to use two tape machines, one playing back the original tapes, and the other recording that playback. Generally this process was used to assemble scenes together, not for creative editing. This process was not always exact, and if imperfectly performed would lead to picture breakup when the cut was played. Since there was no visible frame line on the 2-inch-wide (51 mm) tape, a special ferrofluid developing solution was applied to the tape, allowing the editor to view the recorded control track pulse under a microscope, and thus determine where one frame ended and the next began. One error-prone method option was to cut the tape with a razor blade. When two-inch quadraplex video tape recording was first introduced by Ampex in 1956, it could not be physically cut and spliced simply and cleanly as film negatives could be. Film editors worked with a workprint of the original film negative to protect the negative from handling damage. History From film to tape įilm editing used an offline approach almost from the beginning. This is when it then moves onto the following stages of post production known as online editing, colour grading and audio mixing. Many versions and revisions are done at this stage until the edit gets to a stage known as picture lock. Therefore, the offline editing stage is the creative storytelling stage that defines the structure, mood, pacing and story of the final show.

The editor and director are then free to work with all the options to create the final cut. Typically, all the original footage (often tens or hundreds of hours) is digitized into the suite at a low resolution.

The availability of more powerful digital editing systems has made the offline editing workflow process much 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 Media Composer, Sony Vegas, Lightworks and VideoPad.
Modern offline video editing is conducted in a non-linear editing (NLE) suite. The term offline originated in the computing and telecommunications industries, meaning " not under the direct control of another device" ( automation). Once the project has been completely offline edited, the original media will be assembled in the online editing stage. Offline editing is part of the post-production process of film making and television production in which raw footage is copied and the copy only is then edited, thereby not affecting the camera original film stock or video tape.
