Freelance film editor and FX artist, Alan Edward Bell shares some Hollywood secrets in this discussion of his recent job for 20th Century Fox and New Regency Pictures -- "Little Manhattan." One tool he came back to again and again was GenArts' Sapphire Plug-ins -- both during the editing stage to create effects within Final Cut Pro, and during the finishing stage to finalize the effects at film resolution within Autodesk combustion.

To get a radial (zoom or crash) blur, make the From Z Dist and To Z Dist different from each other. The more different they are, the longer the blur.
To get a rotational blur, make the From and To Rotate different from each other. To get a directional (straight) blur, make the From and To Shifts different from each other. You can combine any or all of these to get any look you want.
Basically the Z Dist, Rotate, and Shift define a transform for the image; the blur happens between the From transform and the To transform.
