Arri are gifting even more features to their ALEXA camera range with the release of ‘SUP 9.0′ Software Update Packet 9.0 for ARRI ALEXA XT cameras and ALEXA Classic cameras.

DNxHD 444 recording will be of great interest to the many corporations and production companies that work with MXF files and the SMPTE-standardised DNxHD codec, which offers high quality at low bandwidths.

With an absence of subsampling or averaging of chroma information, the 10 bit 4:4:4 RGB codec provides an basis for creative grading, colour keying and multi-generational finishing and mastering.

DNxHD 444 clips can be recorded at up to 30 fps on 32 GB SxS Pro cards and up to 60 fps on 64GB SxS Pro cards, CFast 2.0 cards or XR Capture Drives.

Other new features include improved ProRes Recording. ARRI has increased the maximum frame rate of the highest quality ProRes codec (ProRes 4444) to 120 fps in 16:9 HD mode. This requires ALEXA XT cameras or ALEXA Classic cameras with the XR Module upgrade and the use of XR Capture Drives or CFast 2.0 cards. It is now possible to keep shooting ProRes 4444, no matter what the frame rate.
