1. A system comprising:
- means for loading one or more source processing chains to support execution of a development project, the source processing chains comprising a series of filters to process and render media content, wherein means for loading of the one or more processing chains comprises;
means for identifying which source(s) will be required to support execution of the next M seconds of the development project, wherein M is at least as long as necessary to construct a processing chain;
means for searching one or more cache(s) to determine whether the source processing chain(s) associated with the source(s) are available within the one or more cache(s); and
means for retrieving the one or more processing chains from a memory location denoted by an associated one or more pointers in the cache for integration with the development project; and
means for determining whether each of the one or more processing chains will be subsequently required during execution of this or another development project and, if so, means for caching those filter chains which will be subsequently required.

8. One or more computer-readable having computer-readable instructions thereon which, when executed, implement a method comprising:
-
loading one or more source processing chains to support execution of a development project, the source processing chains comprising a series of filters to process and render media content, wherein loading of the one or more processing chains comprises;
identifying which source(s) will be required to support execution of the next M seconds of the development project, wherein M is at least as long as necessary to construct a processing chain;
searching one or more cache(s) to determine whether the source processing chain(s) associated with the source(s) are available within the one or more cache(s); and
retrieving the one or more processing chains from a memory location denoted by an associated one or more pointers in the cache for integration with the development project; and
determining whether each of the one or more processing chains will be subsequently required during execution of this or another development project and, if so, caching those filter chains which will be subsequently required, wherein determining whether a processing chain will subsequently be required comprises;
determining whether any future calls to a source coupled to the processing chain exist within this development project; and
determining whether any future calls to a source coupled to the processing chain may be received during execution of future development projects. - View Dependent Claims (9, 10, 11, 12, 13)
