Setting the System Timing
A new, factory-default PDR200 is configured so that:
• All zero-timed inputs are auto-timed correctly with no adjustments.
• All outputs are zero-timed to the external reference (house black).
• Each input can lock to and record any stable video input, whether or not the
source is genlocked to an external reference.
• Each input is auto-timed to allow precise switching between inputs, provided
the input signals are within the auto-time window. (See “Auto-time Mode”
for each input.)
NOTE: Serial digital inputs (525 lines) without embedded audio must
be timed manually.
To adjust system timing:
1. Choose Options | System Timing or click the System Timing button on the
toolbar. The System Timing dialog box appears (see Figure 10 which shows
an example of how the dialog box looks when the outputs are zero-timed by
default).
- The red line represents the external reference, and the yellow line
represents reference genlock.
- A hashed box represents a timing window or, in other words, the range of
lines within which the timing is adjusted.
- The external reference, represented at the top of the dialog box, shows a
range from –16 to +16 lines. You can scroll past this range by dragging
the pointer on this line in either direction with the mouse.
2. Click any button to the left of the internal reference (genlock) or video output
signal name and the timing edit box appears in the bottom left of the System
Timing dialog box (see Figure 11 which shows the dialog box when the
outputs are E to E timed).
3. In the timing edit box, you can adjust the number of fields (genlock only) or
lines, and also tune these settings with course or fine adjustments. You can
enter a number directly or click an arrow to adjust a setting. The adjustments
and ranges available vary, depending on which input/output you change.
