摘要： An on-line video editing system includes interface software containing in preferably text file format protocol information and a mapping of the architectural functions of peripheral devices that a user can control via the editor. This software allows the present invention to readily control all functions of which a peripheral device is capable, and to issue commands in a synchronized, distributed manner in the proper protocol for the peripheral device. The system permits simultaneous control of up to 48 serial devices (all of which may be switchers) as well as 8 GPI controlled devices, and permits multiple users or multiple simultaneous edits. Further, the interface software enables a user to input (preferably in text file form) a desired edit effect, whereupon the system will make design decisions and construct the desired effect using such devices as are available to the system. Applicants' hardware and EDL software permit the system to maintain a virtual hierarchical historical record of unlimited size containing every step of every edit made with the system, allowing a user to later recreate or partially or completely undue visual effects, including layered effects. In addition to conventional timecode data, the system EDL can provide user output in graphic or visual form, and will allow a user to actually see a still frame from a desired video edit point. The system includes a motorized control that automatically reflects the state of a video source under control while providing absolute or relative positional control.
