S_WarpDrops

Warps the source clip by multiple patterns of concentric waves emanating from multiple center locations. Each area in the Centers input clip brighter than the value of Threshold Cntrs, generates an independent pattern of concentric waves, and the total brightness of each area scales the warping magnitude of those waves. If the Centers image is complex, the number and locations of resulting centers can be fairly sensitive to the threshold value. Try using just solid black with a few white dots for the Centers input. If you only need a single set of waves, you can use the WarpPuddle effect instead.

In the Sapphire Distort effects submenu.


Inputs:

Source:  The current layer.   The input clip to be warped.

Centers:  Defaults to None.   Determines the centers of the wave patterns. Each area in this clip brighter than the value of Threshold Cntrs, generates an independent pattern of concentric waves. The total brightness of the area (brightness x area) scales the warping magnitude of those waves. This clip is often a painted image of dots of different sizes and brightnesses. If the painted centers move over time, the effect centers will move with them.

Matte:  Defaults to None.   If provided, the amplitude of warping is scaled by the values of this input clip. Gray values internally scale the warping amplitude rather than simply cross-fading between the effect and the original source to allow more continuous results at the matte edges and more detailed control over the warping amounts. This input can be affected using the Blur Matte, Invert Matte, or Matte Use parameters.
        

Parameters:

Amplitude:   Default: 1,  Range: any.
Scales the amount of warping distortion. Increase for more severe distortion.

Frequency:   Default: 8,  Range: 0.01 or greater.
The frequency of the waves. Increase for more waves, decrease for fewer.

Rel Height:   Default: 1,  Range: 0.01 or greater.
The relative height of the concentric wave pattern.

Rotate Rel H:   Default: 0,  Range: any.
Rotation in degrees of the wave patterns, about each center. This has no effect if the Rel Height parameter is 1.0.

Threshold Cntrs:   Default: 0.6,  Range: 0 to 1.
Areas brighter than this value are used as centers for the waves. A center is generated from the centroid of each set of connected pixels above this value.

Max Centers:   Integer,  Default: 20,  Range: 1 or greater.
The maximum total number of centers to use. This can be used for testing or to avoid overly large numbers of centers.

Phase Start:   Default: 0,  Range: any.
The phase shift of the waves.

Phase Speed:   Default: 0,  Range: any.
The speed of the waves. If this is positive the waves automatically travel outwards from the center at this rate.

Inner Radius:   Default: 0,  Range: any.
The distance from the puddle center where the wave distortion is phased in. No waves are generated inside this radius.

Inner Softness:   Default: 36,  Range: 1 or greater.
The width of the region at the Inner Radius over which the wave distortion is phased in.

Outer Radius:   Default: 180,  Range: 0 or greater.
The distance from the puddle center where the wave distortion is phased out. No waves are generated outside this radius.

Outer Softness:   Default: 180,  Range: 2 or greater.
The width of the region at the Outer Radius over which the wave distortion is phased out.

Z Dist:   Default: 1,  Range: 0.001 or greater.
Scales the 'distance' of the image. Values greater than 1.0 move it farther away and make it smaller. Values less then 1.0 move the image closer and enlarge it. Zooming in slightly can sometimes be used to hide edge artifacts.

Wrap:   X & Y,  Popup menu,  Default: [Reflect Reflect].
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.

Filter:   Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

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

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

Matte Use:   Popup menu,  Default: Luma.
Determines how the Matte input channels are used to make a monochrome matte.
Luma:  the luminance of the RGB channels is used.
Alpha:  only the Alpha channel is used.

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. If your image has sharp color changes where the matte channel also has sharp edges, you may get better results with Normal mode.

Show Frequency: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show Outer Radius: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show Inner Radius: Check-box, Default: off.
Turns on or off the screen interface parameter for adjusting the Inner Radius. The value of the Inner Radius parameter must first be positive for this widget to be visible.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show Rotate Rel H: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
