TriCaster, however, includes dynamic audio re-sampling for each input. Genlocking of SDI
audio/video sources is not a requirement. Still, genlocking sources and TriCaster to a
house reference signal, or genlocking the cameras directly to the TriCaster output is
encouraged (to genlock cameras, see your camera manual).

Locking all devices to house sync is important, but this alone does not actually ensure
a perfect downstream match. Consider an army marching along: each step the
soldiers take occurs at precisely the same moment, so we could say their timing is
synchronized. Even so – problems result if one soldier leads with the left foot while
everyone else is on the right. Or perhaps everyone is evenly spaced and perfectly
aligned but for one misfit who 'tailgates' the soldier ahead of him and keeps stepping
on his heels.
This is essentially why TriCaster provides several adjustments in its Genlock section.
The Horizontal and Vertical Position settings pin the image in the proper space in the
frame, and in doing so could be likened to making sure each marching soldier is in
position relative to his fellows (as viewed from above).

The Phase setting ensures proper color alignment, corresponding to making sure
everyone is on the left or right foot at the same time.
