Abstract: Information related to a request to generate a new media creative (NMC), which includes new user-specified attributes (NUSAs), is obtained. Historical user-specified attributes (HUSAs) associated with historical creatives (HCs) are obtained from a data structure linking the HUSAs, historical creative parameters (HCPs), and acceptance statuses to the HCs. The HUSAs are associated with HCPs specifying historical content characteristics of the HCs, which are in turn associated with acceptance statuses. Particular HCs having HUSAs that match the NUSAs are selected. Accepted HCs (AHCs) are identified based on acceptance statuses, and HCPs associated with the AHCs are identified. A set of HCPs most frequently associated with the AHCs is selected based on associations among the HUSAs, the HCPs, and the acceptance statuses. A set of new creative parameters (NCPs) specifying new content characteristics of the NMC is selected based on the set of HCPs.

Abstract: A script creation system obtains both current user-specified attributes to be used in generating a new media creative, and historical data including historical user-specified attributes associated with previously generated media creatives. The script creation system generates a set of creative parameters specifying content characteristics of the new media creative based on the user-specified attributes and the historical data. The set of creative parameters are transmitted from the script creation system to a media creative generation system. The script creation system receives the new media creative generated by the media creative generation system, and provides the new media creative to an end user system associated with an end user. The script creation system receives feedback associated with the new media creative, and stores the feedback, the set of creative parameters, and the current user-specified attributes as historical data.
