S_ScanLines Creates a version of the source clip with 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 current layer.   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.

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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Show Lines Angle: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
