S_WarpBubbleWarps the source clip by a smooth noise function. This can be used to create heat diffusion or under water types of effects. The Shift Speed parameters cause the noise pattern to automatically translate over time. Adjust the Amplitude and Frequency parameters to give different types of distortions.In the Sapphire Distort effects submenu.

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.
-
Mocha Project:
Default:
0,
Range:
0 or greater.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
0 or greater.
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.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
-
Invert Mocha:
Check-box, Default:
off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.
-
Resize Mocha:
Default:
1,
Range:
0 to 2.
Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:
1,
Range:
0 to 2.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:
0 to 2.
The relative vertical size of the Mocha Mask.
-
Shift Mocha:
X & Y, Default:
[0 0],
Range:
any.
Offsets the position of the Mocha Mask.
-
Bypass Mocha:
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.
-
Amplitude:
Default:
0.25,
Range:
any.
Scales the amount of warping distortion. Increase for more severe distortion.
-
Frequency:
Default:
16,
Range:
0.01 or greater.
The frequency of the noise pattern. Increase for more and smaller bubbles, decrease for fewer and larger bubbles.
-
Frequency Rel X:
Default:
1,
Range:
0.01 or greater.
The relative horizontal frequency of the bubble pattern. Increase for taller bubbles, decrease for wider ones.
-
Octaves:
Integer, Default:
1,
Range:
1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the amplitude of the previous. A single octave gives a smooth texture. Adding octaves makes the result approach a fractal (1/f) noise texture.
-
Seed:
Default:
0.23,
Range:
0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.
-
Rotate Warp Dir:
Default:
0,
Range:
any.
Rotation angle of the warping directions in counter-clockwise degrees.
-
Shift Start:
X & Y, Default:
[0 0],
Range:
any.
The translation of the bubble pattern.
-
Shift Speed:
X & Y, Default:
[0.1 0],
Range:
any.
If non-zero, the bubble pattern is automatically animated to shift at this speed. The result of animated Speed values may not be intuitive, so for variable speed motion it is usually best to set this to 0 and animate the Shift Start values instead.
-
Z Dist:
Default:
1,
Range:
0.001 or greater.
Scales the 'distance' of the image. Values greater than 1.0 move it farther away and make it smaller. Values less than 1.0 move the image closer and enlarge it. Zooming in slightly can sometimes be used to hide edge artifacts.
-
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.
-
Blur Mask:
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.
- Alpha: only the Alpha channel is used.
-
Luma:
the luminance of the RGB channels is used.
-
Crop Input Parameters:
Default:
0,
Range:
0 or greater.
These 4 parameters, Crop Top , Crop Bottom , Crop Left, and Crop Right , allow selecting a rectangular subsection of the input image to be processed. If the Wrap parameters are set to "No" the exposed borders will be transparent. If the Wrap is "Tile" or "Reflect" the source image is wrapped on the new cropped borders to fill the frame. This can make it easier to avoid artifacts due to distorting an image with bad edges.
