Sapphire Plug-ins for Autodesk: WarpPerspectiveComp


In the S_WarpsComp Plugin.

Transforms the source clip onto a 3D plane with perspective. Adjust the Latitude, Swing, and Roll parameters to rotate the image on various axes, and adjust Shift and Z Dist to translate and zoom. Turn off the Wrap options to give a single non-repeated copy of the image.


Front: The clip to use as foreground.

Back: Optional. The clip to use as background.

Matte: Optional. Specifies the opacities of the Front clip.


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.

Shift: X & Y,   Default: [0 0], Range: any.
Translates the image in its initial frame.

Latitude: Default: 35, Range: any.
Tilts the image up or down in 3D. Positive latitude tilts the image down and negative tilts it up.

Swing: Default: 0, Range: any.
Rotation of the image in degrees in its initial frame.

Roll: Default: 0, Range: any.
Tilts the result from side to side, in counter-clockwise degrees.

Wrap Above Horizon: Check-box,  Default: off.
When the image is sufficiently tilted using the Latitude parameter, a horizon can be seen. When Wrap Above Horizon is check, the image is repeated on both sides of the horizon.

Z Dist: Default: 3, Range: any.
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.

Tele Lens Width: Default: 1, Range: 0.2 or greater.
The amount of lens telescoping. Increase to zoom in with less perspective, decrease for a wider viewing angle with more perspective.

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.

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

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.


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.


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.
