This is essentially why 3P LAY 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 more to the matter of
making sure everyone is on the left or right foot at the same time (Phase adjustment is not
required for HD sessions, so it is not shown in that case).
Thus, the Vert Position, Horiz Position and Phase settings allow you to adjust synchronization to
arrive at an optimal match between devices. (Typically, these settings are tweaked with the aid of
downstream Vectorscope and Waveform monitors.)
A discussion of these adjustments goes beyond the scope of this manual, but a quick online search
for the keywords “genlock” and “adjust’ turns up a number of excellent references.
REFERENCE TYPE
For standard definition 3P LAY sessions, only the traditional “bi-level” reference signal is supported,
so the Reference Type selector is not shown. However, 3P LAY supports both bi-level and the newer
tri-level reference signals for HD sessions.
Use the Reference Type selector to identify the signal supplied to Genlock input. Note that for HD
(Tri-level), the reference signal must conform to the Video Standard and Resolution selected for
the session in the Administration Panel.
NOTE: FOR NTSC SESSIONS, THE REFERENCE SIGNAL MUST BE EITHER 29.97 OR 59.94 FRAMES
PER SECOND.
