(…)Basically TMP had no “Digital Intermediate” as we know it. Shots were digitized as needed, altered and then printed back to film. So the “master negative” of phantom is a cut negative comprising entirely of digital filmouts (with one exception). The resolution of these scans is most definitely 2K and the visual effects rendered at 2K or possibly less depending on the complexity of the scene.
Indeed, the first movie with a full “Digital Intermediate” during its creation process was “O brother where art you” (2000), so one year after TPM.
