Ark Media Incorporates Archival Footage with Teranex 2D Processor

A world premiere at the 2017 Sundance Film Festival, the documentary Oklahoma City from director Barak Goodman explores how a series of deadly encounters between American citizens and federal law enforcement—including the standoffs at Ruby Ridge and Waco—led to the bombing of the Alfred P. Murrah Federal Building in Oklahoma City in April 1995.

Oklahoma City provided a bigger challenge than usual for Brooklyn-based Ark Media. The film was finished at 23.98 fps, requiring the team to up-res and convert more than 400 archival clips. Post supervisor Stephen Altobello explains how Blackmagic Design’s Teranex 2D Processor proved essential: “Oklahoma City takes place in the 1990s, and everything was shot on video, which has generally not aged well. Our producer, Emily Chapman, found footage from archives, local TV stations and personal collections: Beta SP, VHS, DVDs—you name it—all shapes and sizes, all at varying quality. A lot of it had been dubbed or questionably converted at some point in its history, which meant that our post team needed to analyze every clip thoroughly before running it through the Teranex. We purchased Teranex four years ago and have used it regularly ever since. As many of our films have a lot of archival material, we constantly need to up-res something, and Teranex has been our very reliable go-to.”

Allie Corcoran, up-res editor for Oklahoma City, adds, “Teranex takes on issues, especially frame rate conversions that are out of the ordinary, and handles them really well. Teranex doesn’t take away from the quality of the clip. It gives us as close to what we need frame rate-wise as possible.”
