High Speed mode allows recording 60 to 120 fps in 16:9 and 60 to 90 fps in 4:3 (if 4:3 is supported by the camera model). High Speed mode uses the same Super 35 sensor area as Regular Speed mode (same depth of field, same angle of view). Requirements: ALEXA camera with Software Update Packet 5.0 or higher. Always included in ALEXA M, ALEXA Plus 4:3, ALEXA Studio and all ALEXA XT, SXT, SXT W and LF cameras.
