FPS Currently set frame rate of sensor, adjustable from
0.750-60.000 fps in Regular Speed Mode, and from
60.000-120.000 fps in High Speed Mode.
Note: High Speed Mode can only be activated with
valid High Speed license key installed in camera.
AUDIO Shows current level of audio. If Audio is set to Off, the
audio input is switched off, no audio is embedded to
HD-SDI outputs, and no audio tracks are recorded on
the SxS PRO cards. The same applies if audio is
disabled, which is the case if the sensor frame rate is
not equal to the project fps setting (=over- or
undercranking).
SHUTTER Currently set shutter angle of sensor, adjustable from
5.0-358.0°. Shutter Angle and sensor fps determine
exposure time of the sensor in seconds by the
following equation: Angle/(360*Fps).
EI Currently set exposure index rated in ASA. ALEXA
has a base sensitivity of 800 ASA, the camera rating
can be adjusted from 160-3200 ASA.
Note: ASA rating is identical to ISO rating.
Note: Exposure Index is not applied to ARRIRAW
signals.
COLOR Opens color screen, where gamma and look settings
for SxS , REC OUT, MON OUT and EVF can be
changed .
WB Camera white balance. This is the color temperature
of the light source the camera is currently adjusted
for. Can be adjusted from 2000-11000 Kelvin in steps
of 100K. In addition to the red/blue correction of the
white balance, ALEXA can also compensate for a
green/magenta tint. This value, called CC (after color
compensation), is shown as an exponent of the WB
value. Positive values are marked with a "+" and
negative values with a "-".
The camera can also perfom an automatic white
balance upon a button press.

is shown in small digits.
