The NewTek Control Surface for TriCaster 850 and 855 is for the NewTek TriCaster 850 and 855 live production systems, and offers you complete control over video sources and functions in your live production. Mapped directly to the 850/855 Live Desktop, the control surface allows you to conveniently produce live video with resolutions up to 1080p. A premium T-bar offers intuitive control over effects, transitions between sources and other functions, and a 3-axis joystick provides refined control of position, scale, crop and full 3D rotation functions. Transition controls can be done manually or set to automatic for 1-button transitioning between sources. Using Program and Preview Rows, you can select sources for your active and upcoming video output, and the selected sources can be recognized from lit-up buttons. Utility Bus Delegate provides refined control and delegation of the Utility Row, and supports for multiple concurrent selections. Back-lit buttons and twist knobs of the TCXD850 CS Control Surface offer enhanced ergonomics, and a Utility Row provides convenient access to live production utilities, so that you can assign the Effects bus source, select downstream key elements, and manage the AUX output, either individually or simultaneously. The control surface features 1-button video recording (for later use) and 1-button Internet streaming. With Virtual Input Controls, you can select 2 primary switcher sources to create a virtual mix/effect composition, and overlay an additional source as well.
