Here's a quick way: If the direction of the route is mainly in one direction, e.g. south or east, then have two graphics, one without the route drawn and one with.

A directional wipe transition from the "without" to the "with" will reveal the route at whatever speed you want.

The .wmv file is the finished output. Save the other three files (one .veg file and two .jpg files) to your drive and you can see how it was done. Track one is a generated solid color media, used as a mask. Track 2 is the map with the complete route line drawn in. Track three is the map without it. I used pan/crop on track one to move the mask across the screen. This works well for a simple route that is nearly straight. If the route is more complex, you can set more keyframes for the pan, or use track motion instead.

Thanks to both of you for the amazingly quick responses and great ideas.

Chienworks, can I ask you please to expand a bit on the use of track motion? I'm finding that using a mask doesn't work very well for M-shaped (or E-shaped) routes, because the upward (or sideways) moving mask will hit several points on the route at the same time. I'm new to VV and would really appreciate your insights into the use of track motion to avoid this issue.
Thank you.
