The Codex workflow is an end-to-end, camera-to-post system that makes production easier and more efficient than ever before.
The Codex workflow is made up of three types of product – Recorders, Transfer, and Final Delivery systems. You can use them alone or together, depending on your application.
Recorders
Our versatile range of Codex recorders cover all digital production applications – from broadcast studio work to ultimate cinema-quality recording. The Portable or Recorder systems provide hours of continuous recording and revolutionary ways of using the results.
Transfer Stations
These units allow you to make everything from simple backup copies to full production deliverables, right on set or from a location office. As with all Codex products, the Transfer Stations deliver results much faster than real time.

Final delivery
The Transfer Stations integrate seamlessly with the Codex Lab. The Lab is comprised from a series of powerful transcoding and voluminous storage modules, which provide all the deliverables and capacity that any production might need – from rushes to archiving, in a wide variety of formats. They can use many third-party RAID systems.
