Output comprises instructions for producing videos optimized to achieve at least one performance objective. Some embodiments predict performance of existing video, such as predicting winning Super Bowl ads before they air. The system comprises one or more processors and a memory configured to receive at least one data stream of audiovisual content in at least one public and/or a private domain; analyze said data streams to determine one or more attributes associated with said data streams; analyze said data streams to determine one or more performance scores associated with said data streams; attribute at least a portion of one said performance score to at least a portion of one said attribute associated with said data streams, and output, to a memory, any or all combinations thereof.
