How can I make a small colored rectangle which is the background of my text? I can make one with the solid color and get it to the correct size but, then cannot move it to where I desire.
I used Pan/Crop screen to resize with the solid color on the lower track of course.
You might also want to try playing with the cookie cutter instead of using pan/crop and track motion. You can choose a variety of shapes and sizes and feathering and move it around at will, all in one tool.
