High Speed License Key

Arri Licenses » ALEXA License Options » High Speed License Key

The ALEXA High Speed license allows recording 120 fps for slow motion shots on ALEXA cameras with Apple ProRes codecs up to 422 HQ. High Speed mode preserves ALEXA´s renowned 14 stops of native dynamic range and exceptional image quality and uses the same Super 35 sensor area as Regular Speed mode; offering the same cinematic shallow depth of field and the same angle of view for all lenses. All outputs are in 4:2:2 in High Speed mode, so the REC OUT becomes another MON OUT and neither ARRIRAW nor ProRes 444 are available.

Recording in High Speed mode requires the purchase of the ALEXA High Speed license and the use of SONY's new SxS PRO 64 GB card (SBP-64A). They are built to the same tough reliability and environmental standards as the 32 GB cards, and the high end memory technology used assures a high number of read and write cycles for a long card life during which they maintain their high data rates. Even without the High Speed license the SxS PRO 64 GB cards allow recording of ProRes 4444 at 60 fps. Their high data rates, environmental robustness, high reliability and small size make SxS PRO 64 GB cards the perfect recording medium for the ALEXA family of cameras.
