Sapphire Plug-ins for Autodesk: WarpCornerPinMask

WarpCornerPinMask

In the S_WarpsMask Plugin.

Performs a 3D perspective warp of the source image to align the corners with the four indicated points. This can be useful for positioning the source over an object in another clip, such as a billboard or computer screen.

Inputs:

Source: The input clip to be warped.

Mask: 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. Only the red channel of this input is used. This input can optionally be blurred or inverted using the Blur Mask or Invert Mask parameters.

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.

Top Left: X & Y,   Default: [-0.556 0.423], Range: any.
Location of the upper-left corner of the source. This parameter can be adjusted using the Top Left Widget.

Bottom Left: X & Y,   Default: [-0.806 -0.133], Range: any.
Location of the lower-left corner of the source. This parameter can be adjusted using the Bottom Left Widget.

Top Right: X & Y,   Default: [0.611 0.485], Range: any.
Location of the upper-right corner of the source. This parameter can be adjusted using the Top Right Widget.

Bottom Right: X & Y,   Default: [0.389 -0.58], Range: any.
Location of the lower-right corner of the source. This parameter can be adjusted using the Bottom Right Widget.

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.

Bulge: X & Y,   Default: [0 0], Range: -1 to 1.
Distorts the perspective of the warped image, so that it appears to bulge in one direction. A value of 1 gives no distortion. A value of less than one causes the image to stretch toward the upper/right corner, while a value of greater than one causes it to stretch to the lower/left corner.

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.

Blur Mask: Default: 0, Range: 0 or greater, Shared .
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas.

Invert Mask: Check-box,  Default: off, Shared .
If enabled, inverts the mask input so the effect is applied to areas where the Mask is black instead of white.

Params2:

Shutter Angle: Default: 0, Range: 0 or greater, Shared .
Adjusts the shutter angle for motion blur. This controls the amount of time that the simulated shutter is open, and thus the overall amount of motion blur. A value of 0 disables motion blur. A value of 360 degrees will blur over an entire frame, which is the maximum amount of motion blur possible with a real camera. Values above 360 degrees will produce unrealistic results in which the motion of adjacent frames overlaps.

Samples: Integer,  Default: 16, Range: 2 or greater, Shared .
Controls the number of individual renders that are averaged together when applying motion blur. Increasing the number of samples will give smoother results, but will also increase render times. If too few samples are used, there can be visible aliasing or ghosting artifacts. Faster motion will require more samples to avoid artifacts.
