S_WarpWaves Warps the source clip by a wave pattern. You can make the waves move over time by increasing the Phase Speed parameter, or by animating the value of Phase Start. In the Sapphire Distort effects submenu. Inputs: Source:  The input clip to be warped. Mask:  Optional.   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 mask edges and more detailed control over the warping amounts. This input can be affected using the Blur Mask, Invert Mask, or Mask Use parameters.

Parameters:

Amplitude:   Default: 0.1,  Range: any.
Scales the amount of warping distortion. Increase for more severe distortion.

Frequency:   Default: 8,  Range: 0.1 or greater.
The frequency of the waves. Increase for more waves, decrease for fewer.

Angle:   Default: -45,  Range: any.
The rotation angle of the wave pattern in counter-clockwise degrees. If angle is 0, the waves move to the right and are aligned vertically.

Displace Angle:   Default: 90,  Range: any.
The warping direction in degrees relative to the angle of the waves. 0 gives compression-expansion waves, and 90 gives side to side waves.

Phase Start:   Default: 0,  Range: any.
The phase shift of the waves. The wave pattern is translated in the direction of Angle by this amount.

Phase Speed:   Default: 0,  Range: any.
The phase speed of the waves. If this is non-zero the wave pattern automatically travels at this rate.

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 Mask:   Default: 0,  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.

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.

Crop Input Parameters:   Default: 0,  Range: 0 or greater.
These 4 parameters, Crop Top, Crop Bottom, Crop Left, and Crop Right, allow selecting a rectangular subsection of the input image to be processed. If the Wrap parameters are set to "No" the exposed borders will be transparent. If the Wrap is "Tile" or "Reflect" the source image is wrapped on the new cropped borders to fill the frame. This can make it easier to avoid artifacts due to distorting an image with bad edges.
