Sapphire Plug-ins for AVX2: 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 category.


Source: The current track. The clip to be processed.

Background: Optional. The clip to use as background. The output of the effect is composited over this clip.

Mask: Optional. Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source clip.


Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Mocha: Default: 0, Range: 0 or greater.
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

Bypass Mocha: Check-box,  Default: off.
Ignore the Mocha Mask and apply the effect to the entire source clip.

Show Mocha Only: Check-box,  Default: off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

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: 0.1 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.

Line Thickness: Default: 0.05, 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.

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

Mask Use: Popup menu,  Default: Luma .
Determines how the Mask input channels are used to make a monochrome mask.
Luma: the luminance of the RGB channels is used.
Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.

Blur Mask: Default: 0.05, Range: 0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.

Invert Mask: Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
