Abstract

A method, apparatus and computer program product provides for a proxy media editor to combine editing, rendering, and a plurality of output specifications via a unified platform. The proxy media editor accesses at least one output specification and an edit decision list stored on a server system. The proxy media editor receives a request for media output at the server system, the media output associated with an edit decision list stored on the server system. The proxy media editor renders, at the server system, the media output according to the output specification and the edit decision list. The proxy media editor delivers, from the server system, the media output via a media delivery channel compatible with the output specification. Thus, a user can create a single edited video composition in a hosted web-based environment which can dynamically meet the exact requirements of various delivery channels.
