Can you put text over already recorded video? The titles seem to only be added in between segments.

A quick search revealed this: iMovie '11: Add titles over video

In the future you might also use descriptive thread titles, increasing your chances to get an answer.

Also from iMovie Help:

Add titles over video
You can add title text to any video in your project using one of the many title styles available in iMovie.

You can place titles directly over your video, over a solid-color background clip, or over an Apple-designed graphic background or animated background clip.

Do a search in iMovie Help for "titles", and it's the 3rd subject down. Lot of useful stuff in there.
