Timing settings for DigiSuite LE without the digital
module
If you don’t have the optional digital module, the following timing controls
are provided when you click the
Adjust Timing
button in the
DigiSuite LE
Video Out dialog box:
q H Phase
and
Fine-tune H Phase
Use these controls to advance or
delay the horizontal timing of the DigiSuite LE video and key outputs
with respect to your video genlock source. This lets you compensate
for cable delays within your system. Select
Fine-tune H Phase
and
use the corresponding control only if you need to fine-tune the
H Phase
adjustment by subpixels.
Important After adjusting the
H Phase
, make sure you also make an
appropriate adjustment to the
SC Phase
(explained below).
q SC Phase Use this control to advance or delay the video output’s
subcarrier phase with respect to your video genlock source.
Because of the method used to perform the SC Phase adjustment, not
all values between –180 and 180 degrees are supported. If needed, the
value you enter will be clipped to the nearest supported value.
q Key H Phase
Use this control to advance or delay the horizontal
timing of the DigiSuite LE key output and sync signals with respect to
the video output signal. You may need to do this to align your key
images with their underlying images when routing the key output to a
downstream switcher.
To check the external key alignment, set the display source in the
DigiSuite LE Video Out dialog box to Graphic (external key) , then
select Graphic for Key H Phase Adjustment from the Test Pattern list.
