Reference Input (video card):
• This BNC connector allows you to synchronize outputs to your house reference video signal (or black
burst). If you have a sync generator or central piece of video equipment to use for synchronizing other
video equipment in your studio, then connect its composite output here. When Xena outputs video it uses
this reference signal to lock to.For 1080i and 720p modes only, you may also use analog 525 or 625
