s and release prints. The process of negative cutting has changed little since the beginning of cinema in the early 20th century. In the early 1980s computer software was first used to aid the cutting process. Kodak introduced barcode on motion picture negative in the mid 1990s. This enabled negative cutters to more easily track shots and identify film sections based on keykode

Traditionally a negative cutter would then fine cut the negative to match the Editor's final edit frame accurately. Negative would be spliced together to create rolls less than 2000 feet (609.6 m) which would then be sent to the film laboratory to print release prints.

Negative Cutting Software

There have been a number of dedicated software systems that have been developed for and by negative cutters to manage the process of cutting motion picture negative. A number of individual proprietary software systems have been developed starting in the early 1980s. Stan Sztaba developed a system for World Cinevision Services Inc (New York) in 1983 using Apple II DOS and then PRODOS
ProDOS
ProDOS was the name of two similar operating systems for the Apple II series of personal computers. The original ProDOS, renamed ProDOS 8 in version 1.2, was the last official operating system usable by all Apple II series computers, and was distributed from 1983 to 1993...

, this system is still used today. Elliott Gamson of Immaculate Matching (New York) developed a system using MS-DOS

 based systems developed and is still in use today in several countries.
The first commercially available software product was OSC/R , a DOS based application developed in Toronto, Canada by The Adelaide Works. OSC/R was very widely used and at the time was the only negative cutting software on the market until Adelaide Works ceased operation in 1993. OSC/R is still used today in some negative cutting facilities but has been mostly replaced by newer and more advanced systems. Excalibur was a later Windows 98 based product developed by FilmLab Engineering in Britain. Film Fusion is one of the most recent developments and is a Windows XP and Vista based system developed in Sydney, Australia by Popsoft IT.
