Reference Video and Output Setup

„Set up V-Lock and Timing — Use the following steps to set the output V-Lock mode and SDI output timing, if desired.

Note

Remember that this mode can only be set when the Reference Input is set to External.

1.Press the {Output V-Lock}button to toggle the Output V-Lockmode on or off.

~When On, the {SDI Output Timing} button appears. All native inputs are forced to Frame Sync mode, and one frame of delay will be incurred on all native inputs. In addition, on the Input Setup Menu, the {Sync Mode} button is grayed out.

~When Off, you can not set H and V offsets, and the {Sync Mode} button is active on the Input Setup Menu. This mode provides the least amount of delay through the switcher.

Important	When {Output V-Lock}is On, the position of the DSK Cut
	and DSK Fill inputs on screen will change.
	• If the user preference “Black on Invalid Video” is
	turned on, the DSK turns off — because of the change
	in output timing.
	• If the user preference “Black on Invalid Video” is off,
	the DSK will be visible — but in a shifted position. In
	this condition, the video position can be adjusted by
	changing the output timing of the DSK source itself.
	Refer to the “User Preferences Setup” section on page 304
	for User Preference Setup instructions.

2.If {Output V-Lock} is On, press {SDI Output Timing} to set SDI H and V offsets. Use the {SDI H Offset} and {SDI V Offset} controls to set the offsets as desired.

„Set up reference output — Use the following steps to set the reference video output:

1.On the Reference and Output Setup Menu, press {Ref Output} to change the reference video signal that is currently available on the REF OUT connector.

2.Select either Tri-levelor Burst, as required.

Note

The {Ref Output} button is grayed out when certain output formats are selected, and a default signal is automatically provided on the REF OUT connector. In Chapter 5, refer to the “Reference and Output Setup Menu” section on page 197 for details.
