The first section is B-Roll.

The second half is VuMan in the lower right playing with the switcher.  , and the big picture the results of the buttons he’s hitting. 

We had some light in the sanctuary that night for the cameras, as we had just finished wiring up the switcher for use on June 1st. 

This was all shot on the last Friday of May.

VuMan is hearing the music, and affecting the video in time with it.  Cool, right?
