Arri's Alexa supports ProRes 4444 XQ

Arri has become the first camera maker to support Apple’s new ProRes 4444 XQ codec, the highest-quality version of ProRes to date, which is designed to preserve all the detail in higher-dynamic range imagery through post production.

“Working with ProRes has been great for our customers,” said Marc Shipman-Mueller, Arri’s product manager for Camera Systems. “Up until now, the ProRes 4444 330Mbps version has been the workhorse of professional filmmakers using the Alexa. ProRes 4444 XQ has a higher target data rate of 500Mbps that makes it the ideal choice for post production that requires visual effects processing or extreme colour grading.”

“ProRes 4444 XQ is a fantastic choice for high-end mastering and archiving,” added Henning Rädlein, Arri’s head of Digital Workflow Solutions. “ProRes 4444 XQ offers 12-bit RGB encoding with a low compression ratio of 1:4.5 that maintains the superior tonal range of Log C, while providing the speed, ease of use and familiarity of ProRes.”

Final Cut Pro X 10.1.2 fully supports ProRes 4444 XQ for editing, compositing, rendering, and exporting. Arri Alexa XT cameras and Alexa Classic cameras with the XR Module gain ProRes 4444 XQ capability in both HD and 2K via Arri’s Software Update Packet SUP 10, to become the first cameras capable of encoding ProRes 4444 XQ.

SUP 10 is due to be released in August.
