From FD Times:
“ARRI has announced today that existing Alexa cameras can soon be upgraded with internal ARRIRAW.
ARRI and Codex worked together to develop a new XR Module (Xtended Recording) side cover for ARRIRAW uncompressed recording right where your SxS PRO card previously went.”
Gearhead plans to have this upgrade available for the Alexa ASAP.
