Codex: Used to inspect

Codex provides high-resolution digital recording and workflow systems for elite motion picture production.

Codex is the industry standard for data management and image inspection on high-end film sets. Their hardware, including the Compact Drive and SXR Capture Drive, integrates directly with ARRI and Canon camera systems to handle massive RAW data rates. Production teams use the Codex High Density Encoding (HDE) to reduce file sizes by up to 40 percent without losing a single pixel of image quality. This technology ensures that every frame captured is verified and ready for post-production pipelines at 4K, 6K, or 8K resolutions.
