Strassner Editing Systems (SES) was a line of PC-based linear "CMX style" keyboard video editing controllers invented in 1988 by Norman H. Strassner in Los Angeles, California. Over 400 systems were sold up to the time, in 1995, that Strassner sold the company to a San Jose-based company - Videomedia, Inc., makers of the "V-LAN" hardware he used to physically control video tape machines (VTRs), video and audio switchers and special effects devices.
Strassner Editing Systems were used to edit many popular television shows and motion pictures, including MTV's "Real World", The Muppets and the first Muppet Movie.
The success of Strassner Editing Systems was due to Strassner's own expertise as both an off-line and on-line video tape editor. His "wish list" of features were incorporated into his systems, which made him a local hero for editors in Hollywood.
