This tutorial shows how to make a basic video wall using the Track-Level Track Motion function and its numeric key pad in Vegas Pro. There are many ways to make video walls and animate them, but I feel the method shown here is one of the most simple and effective. Once you know how to make this basic wall, it is relatively easy to move up to bigger walls with more complex animations.
