 Montage was reincarnated as Montage II in 1987, and Montage III appeared at NAB in 1991, using digital disk technology, which should prove to be considerably less cumbersome than the Betamax system.All of these original systems were slow, cumbersome, and had problems with the limited computer horsepower of the time, but the mid-to-late-1980s saw a trend towards non-linear editing, moving away from film editing on Moviolas and the linear videotape method using U-matic VCRs.Computer processing advanced sufficiently by the end of the '80s to enable true digital imagery, and has progressed today to provide this capability in personal desktop computers.
