8.2 Items Associated with the Adjust outputs group
This menu group allows adjustments to be made that specifically affect the output 
of the unit, including output resolution and locking/overlaying onto a computer or 
video source.
This menu item allows the lock mode to be selected and the lock source to be 
defined. The top line of the display shows the current detected resolution of the 
selected lock source (RGB1 in this example). The lock mode can be either Off, 
Genlock or Lock & Mix, with the operation of these shown in the following table:
Lock mode Description
Off The output resolution of the Output is defined by the setting 
for Output Resolution and there will be no background 
source visible.
Genlock The output video will be “Genlocked” to the selected lock 
source. The output signal will be synchronous to the input 
sync and adjustable but there will still be no lock source 
visible.
Lock & Mix The output video will be locked to the selected source, the 
syncs will be locked (but with an additional internal video 
processing delay) and the background for the output will be 
that of the Lock source (unless foreground and background 
are swapped).
Frm.lock* The frame rate of the output will be locked to the frame rate 
of the input. This can only work if the output resolution 
frame rate matches that of the lock source frame rate. 
‘Frm.lock’ will flash until a highly stable lock has been 
achieved.
*Only certain models support this.
In both Genlock and Lock & Mix modes the source selected for the lock input 
determines the resolution of the Output image.  The output resolution for the entire 
image can be no different than the resolution of the lock source. All synchronization 
signals are re-generated within the unit so they may look slightly different when 
compared on an oscilloscope to the original source.
In Frame-lock mode, the output resolution is independent of the lock source, but the 
frame-rate must match that of the source (e.g. 1280x1024 60Hz can be frame-
locked to 640x480 60Hz). Frame-lock is very useful for synchronizing a HD-SDI 
output (e.g. 1080i 59.94Hz) to a composite video source (e.g. NTSC), or for scaling 
one resolution to another while avoiding any potential frame-rate conversion 
artifacts.
'H/V shift' can be used to align the output to the input more accurately, but this may 
cause instability until the lock is re-acquired ('Frm.lock' will flash).
