INPUT CLIPS

 1: Input : Image to be blurred.
 2: Matte : Optionally controls where the blurring is done.



SpinBlur   CONTROL PAGE

Centre  (Position  Default: 0.5, 0.5)
     Centre of rotation.

Inner Radius  (Number  Min: 0.0, Max: 10.0, Default: 0.1)
     The start of the blurring.

Outer Radius  (Number  Min: 0.0, Max: 10.0, Default: 0.4)
     The end of the blurred region.

Soft Radius  (Number  Min: 0.0, Max: 0.5, Default: 0.1)
     Control for the way the blur is applied in the blurring region. A value of 0 blurs the entire blurring region with equal strength. Values greater than 0 provide varying degrees of softness of the transition through the blurring region so that circles closer to the middle of the blurring region receive more blur.

Speed  (Number  Min: -360.0, Max: 360.0, Default: 10.0)
     How much the selected region gets blurred. A higher value means more samples are used along the circle going through the current pixel.
Note: Large values are likely to slow down the processing speed quite significantly.

Blur Style  (List Box  Options: Linear | Fade | Twirl In | Twirl Out, Default: Linear)
Linear: the blurring steadily builds up from the centre.
Fade: the overlay indicates the extent of the burring. Building up from the Inner Radius to the maximum by the time it reaches the associated Soft Radius. Continuous till the outer Soft Radius is reached; then dropping off to the Outer Radius.
Twirl In: the blurring increases from the centre at the rate set by the Twirl value.
Twirl Out: the blurring increases towards the centre at the rate set by the Twirl value.
Use Matte  (Checkbox  Default: Off)
     The luminance of this clip is used to modulate the whole effect. Where white it is drawn at full intensity; black the effect will not be seen.

Invert Matte  (Checkbox  Default: Off)
     Reverse the application of Black to White in the Matte clip.

Skippy  (Number  Min: 1.0, Max: 100.0, Default: 5.0)
     To speed up rendering time every nth pixel is used. 1 gives the highest quality but you can get away with higher values if the effect you desire is fast and furious.

Twirl  (Number  Min: 0.0, Max: 100.0, Default: 2.0)
     This is the rate of build up of the blurring. 0.0 is equivalent to Linear.

Edge Duplicate  (Checkbox  Default: On)
     Fills outside with black or duplicates the edges as necessary.

Trim  (Number  Min: 0, Max: 100, Default: 1)
     If the extremes of the input contain dross - e.g. missing 1/2 scan lines of video input - the edges of the input can be trimmed back to give a clean line for duplication.
