Genlock (continued) 

 

 
 

Delay (625/525) 

 
When these controls are used the output signal will 
appear after the input signal with a time delay. 
When not used the module will operate in the 
synchronize mode. 
 

Note that the H and V delay functions are only 
active when the Lock to Input mode is selected.

 

 
H(orizontal) Delay (625/525) 

 
This item allows the horizontal timing of the output 
signal relative to the input signal to be adjusted by 
up to 1 line in 1 pixel steps. The scrollbar will 
adjust this value.  
Selecting Preset returns the setting to the 
minimum horizontal delay. 

 

V(ertical) Delay 

 
This item allows the vertical timing of the output 
signal relative to the input signal to be adjusted, in 
TV lines. The scrollbar will adjust this value. Range 
is from 0 to 624 or 524 lines in 1 line steps. 
 
Selecting Preset returns the setting to the 
minimum vertical delay. 
 

Video Delay Frames 

 
The number of frames that the output signal will 
appear after the input signal may be set with this 
item. 

Note that this function is available in any genlock 
mode and will add to any other delay settings.
