FX Tab Settings
The FX tab lets you preview geometric (visual) effects applied to the image and adjust
aspect ratio and keystone correction.
Visual Effects These selections are made from the pop-up menu. For a complete
description of visual effects, see Visual Effects on page 4.
FX Sliders These three numerical sliders vary in function with the effect selected.
Keystone Correction Keystone correction adjusts the image to compensate for geometric
or angular distortion in beam projections. The box displays the current shape of the
image, and the eight sliders (two for each corner) let you preview keystone corrections.
The inner box for each corner moves the shape of the image horizontally. Moving the
mouse up stretches the corner to the left; moving the mouse down stretches the corner to
the right. The outer box for each corner adjusts the image vertically. Moving the mouse up
stretches the corner up; moving it down stretches it down.
The keystone sliders also set the shape of shutters used in shutter effects, described in
Shutter Effects beginning on page 111.
Setting DMX Values in the Library Preset Tab
To adjust the parameter value from within the LIbrary Window Preset window, click and
hold on the value, moving the mouse either up or down to increase or decrease the value.
Another option is to click and hold the mouse on the value and use the cursor keys to
adjust the value.
