The position of the arrow tracks the selection, the rotation and scale of the arrow indicate the selection's velocity. Note that the arrow is updated continuously and automatically, because its transform values are given by expressions that are based on the source layer.

The name of each new layer is the name of the original layer, with the suffix "_v" appended. The original layer name will be truncated if it is more than 29 letters long, so that the total name fits within the maximum of 31 letters.

Overall Scale:
The arrow will scale up and down in proportion to the magnitude of the velocity. The overall scale of the arrow can be changed via the effects slider in the velocity arrow's layer.

A short but useful script.
Comes in Scripts/(demos) folder with After Effects.
