Arri has recently released a new Software Update Packet (SUP) for ALEXA XT cameras and ALEXA classic cameras with the XR Module Upgrade. SUP 9.0 brings with it a number of new features such as new recording capabilities and codec options. It also provides the basis for the use of new recording media and accessories. Another important thing to take note of is that this SUP includes software update 1.37 for the ALEXA electronic viewfinder, which fixes an issue that was found in the previous version of the EVF software. The full list of new features included in SUP 9.0 follows.
• ProRes 4444 16:9 high-speed recording up to 120 fps
ProRes 4444 recording up to 120fps is now possible when using an XR Capture Drive or CFast 2.0 card.
• Pre-recording for ProRes (loop recording)
This feature allows you to roll the camera before pressing the REC button. With pre-recording enabled, the camera will continuously pre-record frames into a ring buffer. When you press the REC button again, the actual take is started, but the camera keeps the content of the ring buffer and appends frames into a single clip. This is also referred to as cache recording.
To download SUP 9.0, ALEXA owners must log in after completing a one-time registration on the ARRI website. The file can then be downloaded to an SD card for uploading into the camera. In addition to the release notes for SUP v9.0, ARRI has also included an updated user manual.
Please note: There are two separate SUP 9.0 files for the ALEXA XT/XR Module Upgrade and for the ALEXA Classic – make sure that you download and install the correct one. Arri warns not to attempt installation of this SUP on ALEXA Classic cameras with the SxS Module, ALEXA HD, ALEXA HD Plus, ALEXA Fiber Remote or ALEXA Fiber Remote Plus; doing so can cause the camera to malfunction and become inaccessible.
