S_WarpRepeat Transforms the source input multiple times and averages the results. The From and To parameters do not refer to time. They describe the two transformations in space that determine the sequence of repeated warps applied to each frame. In the Sapphire Distort effects submenu. Inputs: Source:  The current layer.   The input clip to be warped. 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:

Steps:   Integer,  Default: 3,  Range: 2 to 100.
The number of times the input image is sampled along the path between the From and To transformations. More steps require more processing time.

Center:   X & Y,   Default: [360 243],  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.

From Z Dist:   Default: 1.5,  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.

From Rotate:   Default: 0,  Range: any.
The rotation angle of the From transformation, in degrees, about the center.

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.

To Z Dist:   Default: 1,  Range: 0.001 or greater.
The 'distance' of the To transformation. Increase to zoom out, or decrease to zoom in.

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.

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.

Exposure Bias:   Default: 0.5,  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.

Wrap:   X & Y,  Popup menu,  Default: [No 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.

Filter:   Check-box,  Default: off.
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 From Transfm: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the From Z Dist and From Rotate parameters.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show To Transform: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the To Z Dist and To Rotate parameters.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

Show From Shift: 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 To Shift: 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.
