Methods and systems for processing media content are described and in at
least some embodiments utilize a composite or composition, which can be
considered as a representation of an editing project as a single track.
Editing projects can have one or more tracks, and each track can be
associated with one or more data stream sources that can have effects or
transitions applied on them. Compositions can be nested inside one
another and provide an economical way for complex editing manipulations
to take place.
