Final Cut Server was Apple's server-based backend for managing Final Cut Studio files (in particular Final Cut Pro) and workflow automation, based on Proximity's artbox package. Final Cut Server can catalogue any file type and allows for the addition of custom metadata to make those files searchable. Final Cut Server runs on Apple hardware but the server is accessed through a Java client that runs on PCs and Macs. In addition to Java, Final Cut Server makes heavy use of the QuickTime framework and requires its installation when used with PC clients.
