From the 1970s onwards electronic editing advanced with more and more sophisticated edit control systems. 1960s style control was starting the machines together by countdown, off the hands of the clock or the high tech remote start cable. Follow the menu items below for the various systems.
The next phase would be true non-linear editing systems, but before that, in the late 1990s came a halfway house - Profile. Follow the link in the menu below for Ross Archer's description of its development and application.
