 - Very fast DPaint method deleted -

Rather slower method follows:

  Another idea I've used is to create "soft edged " wipes using
Imagine/Essence. 'Fracturb' set to add a black texture with a wide transition
on a white plane, and animated over whatever the length of the transition will
be, gives a nice "soft edge" effect when composited with FRED/ADPro. Just
create a plane, turn it perpendicular to the camera and render the frames at
the correct size for compositing with your final images. (You might make the
plane object "bright" so there is even lighting.)

  You could probably use some of the pattern textures, such as Hexagon, to
create a transition that closes up on itself (hexagons get smaller). The
new Essence textures that support alpha channels may yield some interesting
new results. Of course, the native Impulse textures could be used also, its
just that Essence allows for transitions between areas of color (black &
white in this case). I can't recall if you will have to process the resulting
Imagine frames to 8-bit grayscale, I think with ADPro 2.5 you might be able
to load an image as an alpha channel.

  I've done this using DCTV and it was okay as a wipe but a bit slow. With
a PAR it should work great, Digital Broadcaster too!
