MON OUT 1/2/3
MON OUT 1, 2 and 3 are 422 1.5G single link HD-SDI outputs. The output range is
fixed at legal range. MON OUT 1, 2 and 3 offer the same set of parameters, hence
only MON OUT 1 is described in detail.
Frame rate Select to set the MON OUT frame rate to 23.976, 24, 25,
29.97 or 30 fps. The frame rate should, if possible, match
the sensor frame rate to avoid dropped frames or duplicate
frames on the output, which would result in jittery images
during camera movement or when image subjects are mov-
ing.
MON OUT 3 frame rate cannot be set individually, but inher-
its MON OUT 2 frame rate.
Scan format Select to set the type of scan. Which type you use depends
on the downstream equipment the MON OUT is connected
to. Some monitors, video transmitters or switchers are hap-
pier with the p, others with the psf setting.
•
p: Progessive. Images are transmitted line by line from left
to right, starting at the top-left pixel.
•
psf: Progressive segmented frame. Images are first split in-
to fields, which are then transmitted line by line from left to
right.
Surround view Select to set Surround view on the MON OUT On or Off.
When set to on, the additional pixels outside the recorded
image area on the ALEXA’s ALEV III sensor are displayed,
allowing the operator to see outside the recorded image and
keep unwanted objects, such as microphone booms, out
of the shot. To view only the recorded image, set Surround
view to off.
Frame lines +
status info
Select to set frame lines, surround mask, center mark and
status info overlays to On or Off on the MON OUT.
Peaking Select to set peaking on the MON OUT to On or Off, and the
strength of peaking to low, medium or high.
False color Select to activate the false color display on the MON OUT.
The false color display is an exposure tool that overlays the
image with color coding to highlight areas with significant lu-
minance values.
