Overlay image with iMovie

I know this is not what you want but this is really easy in Final Cut Express which was upgraded to Universal today!

There are a couple of different shareware/demos that could allow you to do this: cfx (under Matting/Compositing), eZedia, or Stupendous Software. Most of these allow limited usability. I have tried some of them out before, and they work ok, but there is a better method (in my opinion) if you have purchased Quicktime Pro. I know it's not free, but it really does come in handy if you haven't bought it yet, and in my opinion it is definitely worth the $30.

To do it in QT Pro, just export the final product from QT Pro to a full quality dv file, open it up in QT Pro, and then go File>Open File, choose your picture, and open it. Then use the sliders at the bottom to select the whole track of the picture and copy that. Then go back to the movie and select the whole track. Then go Edit>Add to Selection and Scale. To get it in the bottom-right hand corner, go Window>Show Movie Properties, select Video Track 2, and then Resources, and you can change the size, position, or overlay mode there.

No problem. Glad I could help!

For the iMovie challenged.

I'm desperately trying to put ukulele chord graphics [block chord diagrams] into a video. I have QuickTime pro, but am missing the basics of how to do this. The previous answer went over my head.

I sincerely appreciate your response and patience.

The above instructions for QT Pro are literally as simple as they get ... it wasn't meant to be easy, as QT is not a video editor.

Your best bet will be to get Final Cut Express, especially if you will be making several movies or the graphic will change throughout the video.
