Configuring your video settings
✃
Apply Edge Filtering to Graphics
Select this option to help
eliminate distorted or “ringing” edges in your graphics. These can
result from abrupt changes in brightness at the edges of objects.
Because this option reduces the sharpness of your graphics, you
should select it only when needed. If your graphics have been created
using a program designed for video purposes, such as Inscriber/CG
Supreme or Speed Razor, do
not select this option.
✃
Apply Chroma Filtering to Graphics Select this option to reduce
the chroma bandwidth of RGB graphics, if needed. For most video
editing programs, it’s best that you
not select this option. If your
rendered images appear to be blurred, try clearing this option.
✃
Apply Edge Filtering to Key Select this option to help eliminate
distorted or “ringing” edges in your keyed images. This problem
typically occurs in hard-keyed images where you have abrupt changes
between opaque and completely transparent areas. Because edge
filtering reduces the sharpness of your images, you should apply it
only when needed. For most video editing programs, it’s best that you
not select this option.
Timing settings for DigiSuite LX 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 LX
Video Out
dialog box:
✃
H Phase
and
Fine-tune H Phase
Use these controls to advance or
delay the horizontal timing of the DigiSuite LX 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.
