controls for selecting preset ROI sizes and
setting zoom limits.

3840x2160.

HD-720: Sets the ROI to 1280x720.
SD: Sets the ROI to 720x405.

Zoom Limit: A drop-down menu that allows you to set a zoom size limit. Zoom sizes smaller than the
selected limit will be prohibited. A red horizontal line marks the limit on the slider.
Choose Unlimited Zoom for unrestricted zooming.
NOTE: Setting a zoom limit is very useful for ensuring that the operator does not zoom in further
than is acceptable for the quality of the output video. This limit may change according to
nature of the camera, lens, and lighting conditions.
CLEAR USER: Clears the current User zoom setting.
SET USER: Sets the current zoom size as a new User zoom setting.
Zoom Slider : Clicking or touching and dragging the vertical Zoom slider resizes the ROI. If a Zoom
Limit is set, sizes larger than that limit cannot be selected.
Virtual Cameras A Virtual Camera is a pre-defined ROI that
can be applied quickly. Up to 100 Virtual
Cameras can be created and stored
(Learned) by name. When recalled, that
virtual camera’s ROI can be instantly taken
with a cut, or can transition from the
current ROI at a defined rate or duration.
Name Field: Virtual Cameras can be given names. Type
the name into this field, using the
computer keyboard, before Learning that
Virtual Camera.
Bank: The currently selected Virtual Camera
register bank is displayed in this field.
After clicking on the Bank button, clicking a number on the numeric keypad to the right
immediately selects a new bank of registers, each of which stores up to 10 virtual
cameras (0-9).

immediately select a numbered virtual camera register. Keypad buttons are tallied
orange to indicate that the a virtual camera has been learned into that register.
