I feel a bit stupid. I have been trying to export text, but when i inport it in to fcp it just is not opaque? The background seems to be renderd along. I can not find any way to turn the background off? I am using motion 4.
Nope, much easier than that. Open Motion 5, from the Template Browser start with a "Final Cut Title" template. It'll save it there inside FCP X, give you everything you need, no render needed, way faster and easier.
