Do I need Multi-Viewer?
See my studio setup above.
I'm currently using another program but have been looking at Wirecast for a few things ... production is done on the main iMac, with additional work on Monitor 2.
The "floor monitors" are linked to a HDMI splitter - they exist in OS/X as one monitor. They show the show output, and in effect act as stage floor monitors for me.
Do I need Wirecast Pro to support these? That's a big lift for a pretty basic feature.
