POV-Ray is a rather flexible post-processing tool.  I've done fades, 
wipes, masking, and titling.

For instance, in a few of my IRTC animations I have a warp gate open up 
in space, revealing the yes-it-was-stolen-from-Babylon-5 hyperspace, and 
then ships use the gate to transit from one space to the other.  I have 
one rendering of the ship and the gate in normal space, another 
rendering of the ship and the gate in hyperspace, another rendering that 
is just a mask, and then a final rendering to transition from the normal 
space view where the mask is black to the hyperspace view where the mask 
is totally white.

You can see the two animations where I do this here:
