A method for analyzing media assets such as video and audio files. The method includes providing access to all the frames of a digital media asset. The method includes, with a microprocessor, running a raw analyzer modules to analyze the asset frames to produce sets of raw analyzer result data that are stored in a data cache in a file associated with the asset. The sets of raw analyzer results are linked to the raw analyzer modules with unique identifiers. The digital media asset is played for the raw analyzer modules, which concurrently analyze the temporally-related frames. The raw analyzer results are stored as data tracks that include metadata for the asset such as immutable parameters including histograms. The method includes using a feature algorithm module to generate an analysis result, such as face identification, for the digital media asset based on the raw analyzer results accessed by the identifiers.
