Modifying video input settings
You can modify the video input settings.
• You can select whether the input freezes or displays black when the video input
signal is lost.
• You can select which lines of the vertical blanking interval will be recorded
uncompressed.
• You can set up the VITC reader.
Setting up the VITC reader
NOTE: The VITC Setup page is only available when the system reference is
Reference Black, and the system has one or more SD input boards. Even when
present in the system, HD inputs do not appear on this page to prevent confusion.
All video inputs include VITC readers. A reader has two VITC detection modes:
Automatic and Manual. When you select automatic detection, you can set the range of
vertical interval lines scanned to find the VITC signal pair; lines 10 to 21 by default.
Manual allows you to choose specific line numbers to detect the VITC signals.
Automatic detection is the default setting. In manual VITC detection, you can specify
the lines used to read VITC. Use manual detection when two sets of VITC are embedded
in the video signal.
To set up the VITC reader:
1. Choose Video Input in the Configuration Manager window. The Video Input
dialog box appears.
2. Click Next to navigate to Video Input page 2 of 3.
