ARRI Announces ProRes Ultra-HD Output for Amira


LR-AMIRA right frontARRI announced that a new software upgrade for its documentary-style Amira camera will allow it to record ProRes Ultra-HD (4K) files. The upgrade is expected to be available by the end of the year.

For those productions that need to generate Ultra-HD deliverables, AMIRA will now offer the ability to record all ProRes codecs in at 3840 x 2160 resolution directly onto the in-camera CFast 2.0 cards, at up to 60 fps. This feature, activated through a separate software license and a sensor calibration for existing Amiras, comes in response to feedback from customers that have been quizzed about 4K deliverables by clients.

Amira’s Ultra-HD output will utilize the same 1.2x up-sample filter that allows Alexa’s Open Gate mode to optimize the camera’s image performance for 4K distribution, as well as the same sensor pixels. The up-sample to Ultra-HD happens in camera, and in real time.

The 14+-stop dynamic range remains unaltered, as does the colorimetry. By making that high-quality image data coming out of the sensor compatible with higher spatial resolution formats, the Ultra-HD upgrade answers the concerns about a 4K future.

Wildlife cinematographer Rolf Steinmann, who was nominated for an Emmy Award this year in recognition of his work with Alexa on the BBC’s Wild Arabia series, is currently using his Amira on a movie for Disney Nature. “For cameramen like me who own their gear, the Ultra-HD upgrade is a great way to stay future proof,” he said. “From now on when there’s pressure from the production side to deliver Ultra-HD, I can continue to work with Amira and won’t have to compromise on image quality or on the camera’s robustness and reliability.”
