Methods and systems of processing multi-media editing projects are described. In one embodiment, a software-implemented matrix switch is programmable to route multiple switch inputs to multiple switch outputs and to produce a single output that provides a data stream defined by a multi-media editing project. A request for one or more multi-media files for use in the multi-media editing project is generated by a user computer comprising part of a network where multi-media files are maintained in a network-accessible location. The request is intercepted and a determination is made as to whether a requested multi-media file is located on the user computer. The multi-media file is retrieved if the file is located on the user computer. If the file is not on the user computer, the requested file is sought from the network-accessible location. A multi-media editing project is then produced using the software-implemented matrix switch.
