Abstract: Methods and systems of processing multi-media editing projects are described. In one embodiment, a request for one or more multi-media files is generated on a user computer that comprises part of a network where multi-media files are maintained in a network-accessible location. The file or files are intended for use in a multi-media editing project. The request is intercepted and software executing on the user computer ascertains whether one or more of the requested multi-media files are located on the user computer. If the file or files are located on the user computer, they are retrieved and used. If a file or files are not locally available, the file or files are retrieved from the network-accessible location. In one embodiment, a multi-media file locator object is configured to intercept network-bound requests for multi-media files and determine whether requested files are locally maintained on a user computer.

Abstract: In one embodiment, a network-bound request for a multi-media file is intercepted to determine whether the file is located locally on a user computer. If the file is located on the user computer, it is retrieved. If the file is unavailable locally, the file is retrieved from a network-accessible location. In another embodiment, a file locator is configured to intercept network-bound requests for multi-media files and determine whether the files are available locally using a list that includes local file directories where files may be stored. When a user retrieves a file from a network and saves it in a directory, if the list does not include the directory, the list is updated to include the directory. If the file locator cannot find the file locally, the user is prompted to select a directory where the file is stored, and the list updated to include the directory.

Abstract: A timeline source is described. In an implementation, a method includes examining a plurality of nodes within a media timeline, where at least two of the nodes reference respective media. The media timeline is for exposure over an API. The media timeline is divided into one or more presentations. Each presentation describes rendering of the media for a particular interval of time.

Abstract: A method comprising generating a source chain for use in a development project, generating an identifier which is uniquely assigned to the source chain, and caching the source chain when it is not currently required in the development project. As execution of the development project continues, or during a subsequent project, if the source processing chain is required, it is retrieved from cache.

Abstract: Systems for processing multi-media editing projects are described. In one embodiment, a computing system comprises input means for generating a request for one or more multi-media files for use in a multi-media editing project, one or more processors, one or more computer-readable media having computer-readable instructions thereon which, when executed by the one or more processors, perform a method comprising: intercepting the request; ascertaining whether a requested multi-media file is located on the user computer by checking one or more user-designated directories for the multi-media file; retrieving the multi-media file if the file is located on the user computer; and seeking the requested file from the network-accessible location if the multi-media file is not located on the user computer.

Abstract: 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.

Abstract: A method of generating a filter graph of a development project is presented comprising identifying a plurality of source clips comprising the development project, wherein each source clip represents an access to a source, and combining two or more accesses for two or more source clips into a single access if the two or more source clips satisfy one or more criteria.

Abstract: A method of representing a development project is presented comprising identifying a plurality of sources comprising the development project, determining whether any of the sources are required simultaneously and, if not, dynamically generating a filter graph representation of the development project utilizing a segment filter to couple a source to multiple processing threads.

Abstract: Systems and methods for resolving a partial topology are disclosed. In one embodiment a media engine includes a topology loader module that receives a partial topology from another module associated with the media engine. The topology loader implements logic operations that convert a partial topology into a full topology, which may be returned to the media engine for presentation of the media stream(s) to a user.

Abstract: Methods and systems are described that permit efficient processing of user-defined multi-media editing projects that combine multiple different source data streams into a single compressed data stream that represents the project. The described approaches are directed to ensuring that those compressed source data stream portions that need to be uncompressed for processing are uncompressed and processed, while those compressed source data stream portions that do not need to be uncompressed are not uncompressed. In one embodiment, a unique switch assembly is provided comprising one or more switches each of which being configured to process data streams. The switch assembly is configured to process both compressed and uncompressed data streams to provide the single compressed output data stream.

Abstract: Systems and methods load one or more source processing chains to support execution of a development project and determine whether each of the one or more processing chains will be subsequently required during execution of this or another development project.

Media is processed using the source processing chain(s) and the matrix switch to produce at least one development project.
