Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:
1,
Range:
0 to 2.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:
0 to 2.
The relative vertical size of the Mocha Mask.
-
Shift Mocha:
X & Y, Default:
screen center.
Offsets the position of the Mocha Mask.
-

Lines Frequency:
Default:
50,
Range:
1 or greater.
The frequency of scan lines on the screen. Increase for more lines, decrease for fewer.
-
Lines Sharpness:
Default:
1,
Range:

Range:
any.
The angle in degrees of the scan lines. Set to 90 for vertical lines instead of horizontal. This parameter can be adjusted using the Lines Angle Widget.
-
Lines Shift:
Default:
0,
Range:
any.
Offsets the position of the pattern of lines. A value of 1.0 shifts one entire scan line over, giving the same result as 0.
-
Shift Red:
Default:
0,
Range:
any.
Shifts the red scan lines by this amount, relative to the other lines. Set the red, green, and blue shifts to -.33, .0, and .33 for an out-of-alignment television set look.

-
Gamma:
Default:
1.5,
