In response to feedback from end users and the rapid take-up of the ARRI ALEXA camera system on professional productions of all kinds, ARRI has created a High Speed mode that allows the ALEXA family of cameras to run from 60 to 120 fps with Apple ProRes codecs, using newly released Sony 64 GB SxS PRO cards that offer a write speed more than twice as fast as the current 32 GB cards.
The 120 fps feature will become available with the upcoming release of ALEXA Software Update Packet (SUP) 5.0 and the introduction of Sony’s new 64 GB SxS PRO cards. Like the ALEXA anamorphic de- squeeze feature, 120 fps functionality can be activated with the purchase of a license. Each license is coded to a particular camera and can be enabled by copying the license to an SD card and loading it into the camera. Licenses can also be disabled, allowing rental facilities control over which cameras are sent out with the High Speed mode.
