To say the least, I used to get confused and frustrated whenever I tried to use AvidFX to add a preset text effect to a clip.
It seemed that black backgrounds could crop up at anytime.

This tutorial is my attempt at clarifying the situation.
After you have watched it you will:either;

1. Understand much more about what is going on, or

2. Be even more confused than you were before you saw the tutorial!

Let's hope it will be number 1.
