S_ShakeApplies a shaking motion to the source clip over time with translation, zooming, and/or rotation. The shaking is random but repeatable, so with the same parameters the same shaking motion is generated each time. Turn on Motion Blur and adjust the Mo Blur Length for different amounts of blur. Adjust the Amplitude and Frequency for different shaking speeds and amounts. The Rand parameters give detailed control of the random non-periodic shaking, and the Wave parameters adjust the regular periodic shaking. The X, Y, Z, and Tilt parameters control the horizontal, vertical, zoom, and rotation amounts of shaking respectively.In the Sapphire Distort effects submenu.

1,
Range:
0 or greater.
Scales the amplitude of the shaking motion.
-
Frequency:
Default:
8,
Range:
0 or greater.
Increase for faster shaking, decrease for slower shaking. (Be careful if you animate frequency values because the resulting shake frequency is also affected by the rate of change of the value.)
-
Phase:

0,
Range:
any.
Time shift of the shaking motions. (If you animate this value, its rate of change will also affect the apparent frequency.)
-
Stillness:

Range:
0 to 1.
In Jumpy mode, controls the speed of movement in between jumps.
-
Center Bias:
Default:
0,
Range:
0 or greater.
In Jumpy mode, adjusts the likelihood that each jump will reset the image to its original position. If set to zero, every jump is random. If set to one, every jump will go back to the center.
-
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.
-
Motion Blur:
Check-box, Default:
off.
Options for motion blur of the shaking motion.
-
Mo Blur Length:
Default:
1,
Range:
0 or greater.

-
Seed:
Default:
0,
Range:
0 or greater.

Channels Parameters:
-
Red Amplitude:
Default:
1,
Range:
0 or greater.
The relative amount of shaking in the red channel. Changing this value from the default will cause the red channel to move more or less than the other color channels, resulting in a color fringing or channel separation look.

Red Phase:

The relative phase of the red channel. Positive values will move the red channel ahead of the others in time, causing it to move first and the other channels to follow. Negative values have the opposite effect, causing the red channel to lag behind the others. Small values usually produce the best looks.

-
RGB Frequency:
Default:
2,
Range:
0 or greater.
The frequency of the random color channel shaking.
Other Parameters:
-
Opacity:
Popup menu, Default: Normal
.
Determines the method used for dealing with opacity/transparency.
-
All Opaque:
Use this option to render slightly faster when
the input image is fully opaque with no transparency (alpha=1).
- Normal: Process opacity normally.
- As Premult: Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.
- Normal: Process opacity normally.
-
All Opaque:
Use this option to render slightly faster when
the input image is fully opaque with no transparency (alpha=1).
-
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.
-
Blur Mask:
Default:
0.05,
Range:
0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.
-
Invert Mask:
Check-box, Default:
off.
If on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.
-
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.
