S_Sketch Generates a version of the input with a hand drawn sketched look. The results of this effect can depend on the image resolution, so it is recommended to test your final resolution before processing a clip. In the Sapphire Stylize effects submenu. Inputs: Source:  The current layer.   The clip to be processed.

Parameters:

Style:   Popup menu,  Default: Sketch.
Selects the style of the sketched strokes.

Sketch:  the stroke directions align with the edges found within the image.

Bumpy Sketch:  the strokes are perpendicular to the edges within the image.

Frequency:   Default: 50,  Range: 1 or greater.
The density of brush strokes in the frame. Increase for smaller strokes.

Stroke Length:   Default: 2,  Range: any.
Determines the length of the strokes along the directions of edges in the source clip. If this is negative you can switch between Sketch and BumpySketch styles and vice versa.

Stroke Align:   Default: 0.2,  Range: 0 or greater.
Increase to smooth out the directions of the strokes so nearby strokes are more parallel.

Smooth Colors:   Default: 0,  Range: 0 or greater.
Blurs the source by this amount before generating the brush strokes. Increase to cause the colors of nearby strokes to be more consistent.

Seed:   Default: 0,  Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Jitter Frames:   Integer,  Default: 0,  Range: 0 or greater.
If this is 0, the locations of the strokes will remain the same for every frame processed. If it is 1, the locations of the stokes are re-randomized for each frame. If it is 2, they are re-randomized every second frame, and so on.

Background Color:   Default rgb: [0.8 0.8 0.8].
The color of the background over which the sketched lines are applied.

Line Thickness:   Default: 0.04,  Range: 0 or greater.
The thickness of the sketched lines.

Line Strength:   Default: 0.3,  Range: 0 or greater.
The strength of the sketched lines. Increase for brighter lines, decrease for softer lines.

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.
