RED DIGITAL CINEMA DSMC2 BRAIN with HELIUM 8K S35 Sensor (2018 Unified DSMC2 Lineup) - Manual (Page 136)

HDRX MENU
NOTE: HDRX mode cannot be modified when test signals are enabled.
NOTE: You cannot change the exposure when HDRX is enabled.
In HDRx mode, the camera records two (2) exposures within the interval that it would usually record only one (1). The
primary exposure is normal, and uses the standard aperture and shutter settings (the “A track”). The secondary
exposure is typically for highlight protection, and uses an adjustable shutter speed that is 2 to 6 stops faster (the “X
track”). Since the camera captures twice the usual amount of frames, the maximum available recording frame rate is
halved and the REDCODE compression options are limited.
