Paramount Pictures, looking for new ways to turn its old movies into cash, especially as DVD sales continue to decline, is creating an online video clip service that will allow users to search hundreds of feature films on a frame-by-frame basis. Feeling “the need for speed,” as Tom Cruise put it in “Top Gun”? Log on to ParamountClips.com, search for the exact video snippet you want and press the checkout button. Within minutes — with the price depending on the type of licensing use you have in mind — Paramount will electronically deliver the selection in the format and resolution desired. Most scenes are available in multiple languages. The site, to be introduced on Tuesday, is powered by VideoSense, an automated indexing tool developed by the technology company Digitalsmiths. Using proprietary video interpretation systems, Digitalsmiths allows films to be quickly searched by specific actor, line of dialogue, location, genre or product, among other criteria. Paramount will initially restrict use to business customers — advertising agencies, mobile carriers, foreign broadcasters — that want to license pieces of films for commercial use. The plan is to ultimately open the site to consumers. People wanting to embed a specific scene from “The Godfather” on their blog could go to ParamountClips.com and buy it.
