VIRTUAL INPUTS 

 

 

Virtual  Inputs  are  a  wonderful  TriCaster  innovation,  opening  up 
whole new levels of convenience and production value. 
 
You  can  pre-configure  Virtual  Inputs  as  multi-source  compositions 
(with  or  without  an  overlay)  and  introduce  them  into  your 
productions like any single Switcher source. 
 
Virtual  Inputs  also  provide  TriCaster’s  connection  to  LiveSet, 
NewTek’s  astonishing  realtime  virtual  set  technology,  investing  it 
with great new capabilities. 
 

We illustrated the value of Virtual Inputs back in Section 4.10 of the Live Production Walkthrough 
chapter.  Now we’ll look into this powerful tool in depth.

 buttons in the 

Program

 and 

Preview

 rows (there 

are no Virtual Input buttons in the Switcher’s 

Utility
