5D.CrashZoom

PURPOSE
Simulates the effect of holding the shutter open in a camera with a zoom lens while swiftly changing the focal length of the lens. Similar effects would happen if a camera were dollied very quickly towards a target. Might also be called convergence blur.

INPUT CLIP
Clip to zoom.

XY Center ( Default: image center )
The convergence position on the image. The co-ordinates need not lie within the image. Represented as a white cross on the overlay, which you can click and drag to change the positional values.

Clear area Radius ( Default: 20.0 )
The radius of a circular region centred on the center position within which the image is unaffected. Represented as a yellow circle on the overlay, which you can click and drag to change the Clear Rad area.

Speed (Min: -2.0 Max: 2.0 Default: 0.1)
Moving out radially from the center, every pixel outside the clear center region moves over a distance that is proportional to its distance from the edge of the clear region during the 'exposure time' of the 'film'. 0.0 = no movement; > 0.0 zoom towards; <0.0 zoom away.
