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.

    Default:
   
   0,
   
    Range:
   
   0 or greater.

    Default:
   
   1,

   [0 0],
   
    Range:
   
   any.
   
Offsets the position of the Mocha Mask. 
-

    Check-box,  Default:
   
   off.
   
Ignore the Mocha Mask and apply the effect to the entire source clip. 
- 
   
    Show Mocha Only:
   
   
    Check-box,  Default:
   
   off.
   
Bypass the effect and show the Mocha Mask itself. 
- 
   
    Combine Masks:
   
   
    Popup menu,  Default: Union
   
   .
   
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
- 
     
      
       Union:
      
     
     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.
     
 
- 
   
    Fine:
   
   
    Check-box,  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,   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,  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.
 
 - Tile: repeats a copy of the image.
 
 - 
     
      
       No:
      
     
     gives black beyond the borders.
     
 
- 
   
    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. 
-

    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, or if there is no valid Alpha channel the Red channel is used.
 
 - Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
