3. Click VITC Generator Enable to place VITC on specified lines in the
vertical interval, as specified under VITC Generator Settings in analog
composite video input.
4. Click NTSC with Pedestal to set the video output to NTSC with pedestal.
5. Under Timing Adjustment , you can adjust the timing of the output signal to
compensate for any additional delays in your system. Any changes you make
in this group take place immediately. You can delay at the following levels,
to get the exact amount of delay required:
- ²Vertical Line level (from –2 to +148 lines)
- ²Coarse Horizontal level (from –100 to +100 ms)
- ²Fine Horizontal level (from –100 to +100 ms)
Use the Line , Course , or Fine boxes to set the timing adjustment amounts.
When the timing adjustments are done with a waveform monitor, you can
visually move the signal so that it matches the reference. Click
Default to
reset the values to 0, which is the point where the output signal timing is
aligned with the reference genlock signal.
6. Under Procamp Adjustment , you can modify the output signal to
compensate for any irregularities in the signal path. All changes take place
immediately.
- Enable Procamp must be checked before anything in this group can be
adjusted. This enables you to setup the Procamp and then disable it
without losing the setup.
- ²Luminance (enabled) specifies only the luminance portion of the signal
is output. The signal is black and white.
- ² Gaussian Chroma Filter determines the type of filter used on the
chrominance portion of the signal. If the Gaussian Chroma Filter is
selected, the filter has a long slow roll-off to prevent ringing. If it is not
selected, then a brickwall filter is used. Although this may introduce
ringing into the signal, it maintains the integrity of the signal for multiple
processing. Use the Gaussian Filter as a last step before transmission and
if ringing suppression is required. Do not use this filter if you are doing
multiple processes/passes on the signal or if the material is in component
form.
