S_DistortWarps the source input clip using the gradient of the Lens input clip. This can generate optical glass-like effects as if the source clip were being viewed through an arbitrarily shaped lens. It is best demonstrated when the lens image contains just a few bold shapes or a simple texture.In the Sapphire Distort category.

-
Combine Masks:
Popup menu, ย Default: Union
.
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
-

Uses the area covered by both masks together.
- Intersect: Uses the area that overlaps between the two masks.
- Mocha Only: Ignore the Input Mask and only use the Mocha Mask.
- Intersect: Uses the area that overlaps between the two masks.
-
Union:
Uses the area covered by both masks together.
-
Apply Mask:

.
Control where in the effect the mask is applied - this affects both the input mask and the mocha mask.
-

Check-box, ย Default:
off.
If enabled, apply the mask to the Lens input in addition to the Source input.
-
Fine:
Check-box, ย Default:
off.
If enabled, the warping amount is reduced by a factor of 100. This mode is meant to allow subtle expansion or contraction of the source image near the edges of its matte given as the Lens input.
-
Amount:
Default:
1,
Range:
any.
The severity of the lens distortions. Make negative to invert the direction of the distortions.
-
Amount Rel:
X & Y, ย Default:
[1 1],
Range:
0 or greater.
The relative amounts of horizontal and vertical distortion. This has no effect unless Amount is positive.
-
Blur Lens:
Default:
0.5,
Range:
0 or greater.
Smooths out the edges in the lens image by this amount before using it.
-
Rotate Warp Dir:
Default:
0,
Range:
any.
Rotates the warping direction by this many degrees. If non-zero, this can add some unusual twisting effects to the lens distortion.
-
Wrap:
X & Y, ย Popup menu, ย 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, ย 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:
