Force Field Freeze
The Force Field Freeze option lets you specify whether you want MXPro to perform a
frame or field freeze. This option works in conjunction with the Freeze feature (see
“Freeze” on page 83).
Frame Freeze produces best quality, but it might produce a jittering effect when trying
to freeze objects in motion. In such cases, use a Field Freeze
Field Freeze – MXPro freezes only every other line of the image. This produces a fast
freeze, but image quality degrades somewhat. To use Field Freeze, set the Force Field
Freeze option to 1.
Frame Freeze – MXPro freezes every line in the image. The freeze takes slightly longer,
but the image quality matches the original because it uses all of the video signal. To
use Frame Freeze, set the Force Field Freeze option to 0 (zero).
GPI Out Mode
This setting determines whether MXPro provides a GPI output to an external device,
such as a character generator, thereby allowing you to trigger an external event based
on an action from the MXPro. Set the value to 0 (zero) to use MXPro with an edit con-
troller, such as the Videonics Edit Suite or Video ToolKit. Set the value to 1 to enable GPI
output to trigger a Character Generator, such as the Videonics TitleMaker.
CAUTION
MXPro also accepts values 2 through 4 for this option. However, using any of these
values might cause your equipment to malfunction and should not be used.
See “Using a GPI Device” beginning on page 126 for relevant information.
Comb Filter
This option can be used in some cases to affect the quality of the video coming from
and input source. Normally, you should leave this set at the default – 1 or On. Change
it only if asked to do so by a Videonics Customer Support Representative.
Black Level
Video equipment commonly uses one of two black level settings:
• 7.5 IRE – The traditional black, which is the MXPro default setting.
• 0 IRE – A darker black level favored by a variety of modern equipment.
To use the darker black (0 IRE) for the MXPro background and border colors, set Black
Level to 0 (zero).
If you are working with equipment that requires 7.5 IRE, set Black Level to 1.
Note
Black Level is not available on PAL versions of MXPro.
