Vision Operator’s Manual (v12.0 MD) Lighting & Preprocessor Effects • Ops 16–5
Preprocessor Effects
Preprocessor effects allow you to perform a number of static effects to a channel. These effects
are applied directly to the channels and are not associated with other Squeeze & Tease MD
effects, such as a wipe.
You can apply multiple Preprocessor effects to the same channel without affecting other channels,
or other Preprocessor effects. Multiple effects on the same channel are cumulative, producing a
combined effect.
Operating Tip — You can use the Channel button on the S&T MD Preprocessor Menu to
select the individual channel, or group of channels, that you want to apply a preprocessor effect
to.
Defocus
The Defocus effect adds a horizontal and vertical blur to the image on the channel.
Use the following procedure to apply a defocus effect to a channel:
1. Press the SEL button on the Keyers Module for the Keyer that you want to apply
preprocessor effect to the channel for. The S&T MD Position/Crop Menu 1-2 is
displayed. The key must already be flying.
2. Press the DVE quick navigation button to display the S&T MD Main Menu 1-2.
3. Press Preprocessor on the S&T MD Main Menu 1-2.
4. Toggle Defocus on the S&T MD Preprocessor Menu to On to apply this effect.

5. Use the Horiz. Defocus knob on the S&T MD Preprocessor Menu, or positioner, to
adjust the amount of horizontal defocus.
6. Use the Vert. Defocus knob on the S&T MD Preprocessor Menu, or positioner, to
adjust the amount of vertical defocus.
7. Use the Overall knob on the S&T MD Preprocessor Menu, or positioner, to adjust the
amount of horizontal and vertical defocus.
This completes the procedure for applying a defocus effect to a channel.
