Sapphire Plug-ins for Autodesk: TrailsMatte

Feedback: TrailsMatte

In the S_FeedbackMatte Plugin.

Similar to the Trails effect, but the current frame is composited over the previous frames using a Matte input, to give a variety of 'time trails' effects. The output of each processed frame is stored and then combined with the next frame. The trails are reinitialized whenever any non-consecutive frame is processed, either the first frame, reprocessing a given frame, or jumping to another frame. You must process multiple frames of a clip in a row to observe the effect.

Inputs:

Source: The clip to be processed.

Matte: The opacity values for the Source clip. Areas of the new Source frames are composited over the previous frames where this Matte input is white.

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.

Fade: Default: 0.8, Range: 0 or greater, Shared .
For each frame, the previous output is scaled by this amount before it is combined with the new input frame. Normally this value should be less than 1.0 which causes previous frames to fade out over time. A value of 1.0 causes no fading, and values greater than 1.0 cause previous frames to become brighter over time.

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

Blur Amount: Default: 0, Range: 0 or greater.
The previous frames are blurred by this amount for each new frame. This has no effect unless it is positive.

Blur Rel: X & Y,   Default: [1 1], Range: 0 or greater.
The relative horizontal and vertical amounts of the blurring. This has no effect unless Blur Amount is positive.

Comp Premult: Check-box,  Default: off, Shared .
Enable this for a better composite if the Foreground pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.

Fade Color: Default rgb: [1 1 1], Shared .
For each frame, the previous output is scaled by this color before it is combined with the new input frame. This is similar to Fade but affects the colors of the previous frames instead of just the brightness.

Color: Default rgb: [1 1 1], Shared .
Scales the color of all frames. Set this color to the complement of Fade Color to offset overly colored trails.

Hue Shift: Default: 0, Range: any, Shared .
Shifts the hue of the previous frames' colors, for each new frame.

Output Matte: Check-box,  Default: off, Shared .
If enabled, the processed Matte channel is output instead of the regular output, for potential use in future composites onto other backgrounds.

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.

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.
