Sapphire Plug-ins for Autodesk: Streaks

Streaks

Motion blurs the bright areas of the source into streaks between the From and To transformations. This can be used to create an extended film exposure effect, or simulate soft beams of light. From and To parameters do not refer to time. They describe the two transformations in space that determine the style of blur applied to each frame.

Inputs:

Source: The clip to be processed.

Parameters:

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.

From Z Dist: Default: 1, Range: 0.001 or greater.
The 'distance' of the From transformation. This zooms about the Center location when Shift is 0. Increase to zoom out, decrease to zoom in. This parameter can be adjusted using the From Transfm Widget.

From Rotate: Default: 0, Range: any.
The rotation angle of the From transformation, in degrees, about the center. This parameter can be adjusted using the From Transfm Widget.

From Shift: X & Y,   Default: [0 0], Range: any.
The horizontal and vertical translations of the From transformation. This can be used for directional motion. If it is non-zero the center location becomes less meaningful. This parameter can be adjusted using the From Transfm Widget.

Center: X & Y,   Default: [0 0], Range: any.
The center of rotation and zooming, in screen coordinates relative to the center of the frame. The shift values should be zero for this location to make sense. This parameter can be adjusted using the Center Widget.

Exposure Bias: Default: 0, Range: 0 to 1.
Determines the variable amount of exposure along the path between the From and To transformations. A value of 0 causes more exposure at the From end, 0.5 causes equal exposure along the path, and 1.0 causes more exposure at the To end. If you have bright spots on a dark background, a 0 value would cause the processed spots to be brighter at the From end and dark at the To end, and a 1.0 value would cause the opposite.

To Z Dist: Default: 0.8, Range: 0.001 or greater.
The 'distance' of the To transformation. Increase to zoom out, or decrease to zoom in. This parameter can be adjusted using the To Transform Widget.

To Rotate: Default: 0, Range: any.
The rotation angle of the To transformation, in degrees, about the center. Note that if the From and To Rotate angles are very different, the interpolation between them will become less accurate. This parameter can be adjusted using the To Transform Widget.

To Shift: X & Y,   Default: [0 0], Range: any.
The horizontal and vertical translations of the To transformation. This can be used for directional motion. If it is non-zero the center location becomes less meaningful. This parameter can be adjusted using the To Transform Widget.

Mix Src Darks: Default: 1, Range: 0 or greater.
The dark non-streaked components of the Source are scaled by this amount and added to the result. This allows combining the streaked and non-streaked versions of the source clip.

Mix Src Brights: Default: 0, Range: 0 or greater.
The original bright components of the Source that were used to generate the streaks are scaled by this amount and added to the result. This allows combining some non-streaked bright areas of the source clip with the output.

Scale Streaks: Default: 1, Range: 0 or greater.
Scales the brightness of the streaks.

Scale Result: Default: 1, Range: 0 or greater.
Scales the brightness of the result.

Threshold: Default: 0.5, Range: 0 or greater.
Streaks are generated from locations in the source clip that are brighter than this value. A value of 0.9 causes streaks at only the brightest spots. A value of 0 causes streaks for every non-black area.

Threshold Add Color: Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the streaks generated on areas of the source clip containing that color.

Wrap: Popup menu,  Default: No .
Determines the method for accessing outside the borders of the source image.
No: gives black beyond the borders.
Tile: repeats a copy of the image.
Reflect: repeats a mirrored copy. Edges are often less visible with this method.

Subpixel: Check-box,  Default: on.
If enabled, uses a better quality but slightly slower method for rendering the streaks.

Streaks Res: Popup menu,  Default: Full .
Selects the resolution factor for the streaks. This is similar to the general 'Res' factor parameter, but it only affects the streaks: the original mixed with the streaks remains at full resolution. Higher resolutions give better quality, lower resolutions give faster processing.
Full: Full resolution is used.
Half: The streaks are calculated at half resolution.
Quarter: The streaks are calculated at quarter resolution.

Combine: Popup menu,  Default: Add .
Determines how the streaks are combined with the background.
Add: causes the streaks to be added to the background.
Screen: performs a blend function which can help prevent overly bright results.

Params2:

Params3:

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

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
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, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

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

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

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