Twirl effect
The Twirl effect distorts an image by rotating a clip around its center. The image is distorted more sharply in its center than at the edges, causing a whirlpool result at extreme settings.
- Angle
- How far to twirl the image. Positive angles twirl the image clockwise; negative angles twirl it counterclockwise. For a whirlpool result, animate the angle.
- Twirl Radius
- How far the twirl extends from the twirl center. This value is a percentage of width or height of the clip, whichever is greater. A value of 50, for example, produces a twirl that extends to the edges of the clip.
