Light Iron Uses Quantel Pablo to Grade The Social Network

London, UK – Quantel’s Pablo 4K was used to perform final color grading and editorial finishing for David Fincher’s The Social Network, the first film originating on the RED One Mysterium-X sensor. Light Iron Digital, Los Angeles, helped design and customize a 4K to 2K workflow for the project spanning digital intermediate through digital distribution with Pablo as its focal point. The Social Network was released 1 October by Columbia Pictures.
The production of The Social Network entailed a seamless workflow that incorporated the strengths of both 4K and 2K and was both tapeless and nearly “film-less.” (The only use of film was at the very end when 35mm prints were made for theaters not equipped with digital projectors.) Fincher and cinematographer Jeff Cronenweth shot the film in 4K with Red ONE digital cinema cameras. The original camera files were processed by 1st assistant editor Tyler Nelson using RED Rocket acceleration cards in near real-time to Apple ProRes for creative editorial (conducted by Rock Paper Scissors’ Angus Wall and Kirk Baxter). Files were conformed from 4K to 2K DPX then delivered to Light Iron colorist Ian Vertovec for final grading and editorial finishing.

“We experimented with the elimination of a traditional laboratory infrastructure on this digital intermediate,” says Light Iron CEO Michael Cioni. Final post work was accomplished in a “temporary” DI theater set up by Light Iron on a soundstage at Red Studios Hollywood. The theater included a Pablo 4K, made mobile from Light Iron’s Los Angeles facility, along with a Sony T420 4K digital projector and a 40-foot wide screen. The unusual set up allowed Vertovec and Fincher to grade the film in an environment whose size was roughly comparable to a large public movie theater.

Setting up a DI theater on a soundstage was made possible by the small size of the Pablo 4K, its low power requirements, and its physically small, yet efficient (dillion) disk array. All iterations of the film, including multiple versions of 1000 visual effects shots, were stored locally on the Pablo in a 4-foot-tall mobile cart.

The temporary DI theater not only provided an ideal environment for viewing and grading media, it also provided maximum efficiency. Cioni pointed out that because Pablo has the ability to read R3D files natively, some projects can avoid the transcoding process altogether. The system also has the unique ability to read creative editorial AAF Files natively. “That means complex decisions made by the editors are better preserved and not lost as what happens with systems that can only read an EDL,” he says.
