To darken or lift the pedestal, drag the control left or right. Holding the command key on a Mac,
or the Control key on Windows, allows only pedestal adjustments.
The iris/pedestal control illuminates red when its respective camera is on air
Zoom Control
When using compatible lenses with an electronic zoom feature, you can zoom your lens in and
out using the zoom control. The controller works just like the zoom rocker on a lens, with
telephoto on one end, and wide angle on the other. Click on the zoom control, located above
the coarse slider, and drag up to zoom in, or drag down to zoom out.
If your lens does not have active lens control or your camera does not support zoom control via
the SDI camera control protocol then these settings will have no effect. For example, EF lenses
do not have built in servos that can zoom the lens electronically so will not be zoomable with
ATEM camera control.
NOTE Analogue B4 lenses do not support ATEM zoom control. For more information
on analogue B4 lenses refer to the 'using servo zoom lenses' section
Coarse Setting
The coarse setting is located to the left of the iris/pedestal control and is used to limit the iris
range. This feature helps you prevent over exposed images from going to air.
To set your coarse threshold, completely open the iris using the iris control, then drag the
coarse setting up or down to set optimum exposure. Now when you adjust the iris, the coarse
threshold will prevent it from going above optimum exposure.
Iris Indicator
The iris indicator is located to the left of the iris/pedestal control and displays a visual reference
so you can easily see how open or closed the lens aperture is. The iris indicator is affected by
the coarse setting.
