Fast Zoom Effect to New Camera
On the outgoing footage add a qucick zoom at the end, on the incoming
footage add a quick zoom at the beginning (animate the scale of the
clips using whatever tools your NLE has for this). If the outgoing
zoom is a zoom in, then zoom out, and vice-versa.
Add a dissolve between the two clips that is the same length as the
zoom. The whole thing needs to be very quick, 12 frames or so tops.
A radial blur can help as well to simulate motion blur.


I wrote a FCP (version 7 or lower) plugin that did this as a transition effect. I can dig it out if you want it.
