    • 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.
    • 在线视频编辑系统包括界面软件,其中包含优选文本文件格式的协议信息和用户可通过编辑器控制的外围设备的架构功能的映射。 该软件允许本发明容易地控制外围设备能够执行的所有功能,并且以外围设备的适当协议以同步的分布式方式发出命令。 该系统允许同时控制多达48个串行设备(所有这些设备可能是切换台)以及8个GPI受控设备,并允许多个用户或多个同时编辑。 此外,接口软件使得用户能够输入(优选地以文本文件形式)所需的编辑效果,于是系统将使用系统可用的设备进行设计决策并构建期望的效果。 申请人的硬件和EDL软件允许系统保持无限大小的虚拟分层历史记录,其中包含用系统进行的每个编辑的每一步,允许用户稍后重新创建或部分或完全不必要的视觉效果,包括分层效果。 除了传统的时间码数据之外,系统EDL可以以图形或视觉形式提供用户输出,并且将允许用户从期望的视频编辑点实际看到静止帧。 该系统包括一个电动控制,可自动反映视频源的状态,同时提供绝对或相对的位置控制。
