S_ScanLines

Creates a version of the source clip with a scan line pattern resembling a color TV monitor. Increase the Add Noise parameter to also add a grainy effect to the result.

In the Sapphire Stylize effects submenu.


Inputs:

Source:  The clip to be processed.
        

Parameters:

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: 0 or greater.
Scales the severity of the lines. Increase for sharper edges, or decrease for a more subtle effect. A sharpness of zero reduces the scan line effect to nothing.

Lines Angle:   Default: 0,  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: -5 to 5.
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: -5 to 5.
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.

Shift Green:   Default: 0,  Range: -5 to 5.
Shifts the green scan lines by this amount.

Shift Blue:   Default: 0,  Range: -5 to 5.
Shifts the blur scan lines by this amount.

Add Noise:   Default: 0,  Range: 0 or greater.
If positive, this much color noise is added to the image.

Noise Freq Rel:   Default: 1,  Range: 0.01 or greater.
The frequency of the noise, relative to the frequency of lines. This has no effect unless the Add Noise parameter above is positive.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the result.

Scale Color:   Default rgb: [1 1 1].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.

Offset:   Default: 0,  Range: -8 to 2.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.

Gamma:   Default: 1.5,  Range: 0.1 to 10.
Scales the brightness of the image by a curve using this gamma value, allowing adjustment of the middle gray values in the scan lines. This can help make the average brightness of the output match the input.

Saturation:   Default: 1,  Range: 0 to 10.
Scales the color saturation. Increase for more intense colors. Set to 0 for monochrome.

Smooth Source:   Default: 0,  Range: 0 or greater.
If positive, the source clip is blurred by this amount before being processed.

Show Lines Angle: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Lines Angle parameter.
