Add Graphics To A Movie?

Is it possible to superimpose graphics over existing video footage in an iMovie project? What I want to do is to add arrows and text to point out certain things on screen but can't work out how I would do this.

I have iMovie 8 and iMovie HD 6

I've never done it in iMove, the only thing I could think of would be to try to use an image with a transparent background, and place it into / ontop of the video clip. You may have to just use still frames of the video and put the arrows in that way.

I know you can do it in FCP, and I think you can do it in FCE. I haven't ever tried to do anything like that in iMovie.

FCP will do it, and you can use Motion as well to spice things up even more. But for the basics, you could actually accomplish it with Quicktime Pro.

Start by dragging the image overlay that you want onto the video. Then open up the Movie Properties with "Command-J".

Select the video layer that is your image, and use the visual settings to adjust it's size, position, and opacity as needed, and mark it's in and out points.

Then, export, and viola! You have your graphical overlay!

(PNG files with transparencies work best, in my experience)
