Setting the Reference Genlock
The Reference Genlock dialog box sets the genlock parameters for VITC reader
settings and internal reference timing. At the top of the dialog box, the status
indicators display the current status of the genlock input: Locked to External
Reference, Internal Clock Locked and VITC Present. A green light indicates
that a particular status is on. These indicators cannot be edited.
To change the reference genlock settings:
1. Click or double-click Genlock from the configuration tree and the Reference
Genlock dialog box appears (see Figure 9).
Figure 9. Reference Genlock dialog box
2. Click Automatic VITC Detect to have the Profile disk recorder use the range
set in the From and To lines to look for the VITC (vertical interval timecode)
signal. If the VITC signal is found, the VITC Present indicator is turned on.
Otherwise, when you do not use Automatic VITC Detect, the disk recorder
expects to find the VITC signals on VITC Reader Line 1 (default 10) or Line
2 (default 12).
