I am trying to add a drop shadow effect to text in iMovie. The problem I'm encountering is that there doesn't appear to be a drop shadow setting and the effect is applied seemingly at random. All the sites I have found online refer to this as the outline effect, but it is a separate effect entirely. I have yet to find reference to how to manipulate the drop shadow on text in iMovie.
For example, here is what text looks like when using the "lower third" text template. It appears without a drop shadow, with no means of adding it. This is the type of text I want to add drop shadow to.

And here is text created using the "scrolling credits" text template. It appears with drop shadow, but if you edit the preset text it may or may not retain the drop shadow.

Where is the control for drop shadow?
