The S_Crosshatch filter comes from the Emmy award winning Boris FX Sapphire filter set.

Stylize.

To select a preset, pick one from the Presets window.

Selects pencil or chalk modes.

Simulates dark pencil or pen strokes on white paper.

Simulates white chalk strokes on dark paper.

Increase for smaller, finer strokes; decrease for broader strokes.

Average length of the strokes, compared to their width.

Overall size and strength; decrease for fewer, smaller strokes. At 0, strokes will vanish. Increase for bolder, more overlapping strokes. At 1, there will be strokes everywhere, so you won't see the stroke pattern.

Softness of the edges of each stroke. Decrease for hard edged pen strokes; increase for a softer chalk like look.

Angle of the strokes in degrees; zero makes strokes horizontal and vertical.

The darkest areas get double overlapping strokes (or pure black in chalk mode). Source areas with luma darker than this threshold are considered in the darkest band and get those double strokes. Increasing this, or any threshold, will darken the overall result since more of the image will fall into the darkest band.

Midtones are divided into darker−mids and brighter−mids. This threshold sets the luma value that separates those two bands. The darker mids get darker and denser strokes.

The brightest areas get the lightest strokes--normally just white, unless you are in chalk mode. Areas brighter than this threshold are considered brights.

Adds or subtracts from all the thresholds. Increase to darken the overall result or decrease to lighten the overall result.

Softens the borders between the dark/mid/light luma bands.

Increase to use more of the source color to color the strokes. 0 means use the stroke color, while 1 means use the color of the underlying image. In between strokes, the background color shows through. If you have Back Style set to Source, the strokes will disappear when set to 1.

The color to use for the strokes. In Pencil mode, this defaults to black. In Chalk mode, it defaults to white.

Posterizes the source, giving a more cartoony look with areas of solid color. This only has an effect when using the source to colorize the strokes or when using the source as the background.

When posterizing, smooth the edges of the solid−color areas. This avoids aliasing and usually looks better.

Adjusts the phase of the posterization. Use this to position the areas of flat color and avoid edges in the middle of areas you'd like to keep flat.

Adds cartoon like edges to the look.

Adjusts the width of the edge strokes. Increasing this value also softens the edges.

Increase to remove minor, insignificant edge strokes, giving a bolder look.

Sets the color for the edge strokes.

Increase to suppress small, minor edges.

Sharpens the edge strokes.

What to use as the background, underneath the pen strokes.

Use the source as the background. This gives a much more colorful look, as if the strokes are drawn over the original clip. You may want to adjust Stroke Color when using this.

Use the specified Solid Color background.

The color to use for the background when in Solid Color mode.

Blur the source before using it as background or to color the strokes. This can help reduce sparkling due to a noisy or grainy source.

At 1, the effect appears only in the white areas of the alpha channel. At 0, the effect appears everywhere in the frame.

Increase or decrease the overall saturation of the output.

Scales the brightness of the result by this amount.

Add a gray value to the darker regions of the source. This can be negative to increase contrast.

Scales the result by this color, thus tinting the lighter regions.

Adds this color to the darker regions of the result.

Interpolates between the result (when set to 0) and the original source (when set to 1). 0.7 can give a nice effect by blending some of the source in with the strokes.

Initialize the random number generator for the strokes. Different values produce different random stroke patterns.
