Blurs the video from the center outwards, like the sun’s rays, and uses a zoom effect.

Figure 10.83: For clarity of presentation only 3 fields are shown

X,Y
  center of the origin field.
Radius
  Zoom on the fields.
Steps
  number of blur steps to be used in the calculation. Increasing the number takes more CPU.
Clear
  With the Clear buttons we can bring the slider to default values without affecting the other parameters.
Reset

You can use sliders or, for maximum precision, you can use the input box. Figure 10.83 shows the parameters: Radius=21 and Steps=3.
