ScanLines In the S_ScanLines Plugin. 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. Inputs: Source:  The clip to be processed.

Parameters:

Lines Frequency:   Default: 50,  Range: 0 or greater,  Shared.
The frequency of scan lines on the screen. Increase for more lines, decrease for fewer.

Lines Sharpness:   Default: 1,  Range: 0 or greater,  Shared.
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,  Shared.
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.

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

Offset:   Default: 0,  Range: any,  Shared.
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 or greater,  Shared.
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.

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

Lines Shift:   Default: 0,  Range: any,  Shared.
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.

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

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

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.

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

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

Noise Freq Rel:   Default: 1,  Range: 0 or greater,  Shared.
The frequency of the noise, relative to the frequency of lines. This has no effect unless the Add Noise parameter above is positive.
