Zodiac was shot with the Viper camera in "FilmStream" mode. The 1:2.37 picture was captured at 1920x1080 pixels. A dual HD-SDI link transfers the image information to the 'dfr' ('dfr' stands for digital field recorder, essentially a linux computer with an HD IO card.) Dual HD-SDI is necessary to transfer the full color information (10bit 4:4:4) from the camera.
Image information and metadata (camera, scene, setup, take, timecode, gps, etc.) are stored as DPX files. At this point, the image is already in it's final (non-color corrected) format and can be played back in it's native resolution. The dfr stores data on a shuttle disk system called "d.mag". Each of these units contains roughly 400 Gigabytes or 34 minutes of 1920x1080x10bit @ 24fps.
