Essentially, the numeric controls in this group allow you to define independent margins for the frame. Drag
left or right on the number fields to adjust the values interactively, or double-click a field to type a value using
the keyboard. The region defined by these controls will be completely cropped. Use the Feather setting
(TriCaster 8000 only) to soften the edges.
Hint: For added convenience, similar cropping tools are available separately in the Position panels of DSK channels
and M/Es.
8.2.5 PTZ
FIGURE 71
PTZ (pan-tilt-zoom), or ‘robotic’ cameras can play important roles in certain types of productions. These
systems range widely in price, from a few hundred dollars to those in the ‘six figure’ range, with an equally
diverse range of quality and features.
Generally, remote control of PTZ cameras involves sending instructions to the camera across either serial
(RS232. RS422, orRS485) or network connections. TriCaster support for both types (see note below).
connection settings shown in the PTZ tab (Input Settings tab) update depending on which Camera type you
select.
Choose your camera protocol (or one similar to it) using the drop-down menu, and then enter (or select)
appropriate settings for the unit. The Flip Camera switch inverts the image, helpful when the camera is
mounted in an upside-down orientation. It also affects the pan and tilt controls, when possible (this support
varies by camera).
