Videocue is the best way to create, record, and publish videos of you speaking directly to a camera.
Videocue marries a teleprompter (what a TV anchor uses to read the news), and your camera (iSight, DV camera, etc).
The result is professional movies or audio files you can use to podcast, videoblog, email, burn to CD, or put on your website.
Using Videocue means you never forget the words you want to use. When you make a mistake, you just stop, and re-record.
You can even include other movies or images as part of your presentation.
Once you are done, Videocue even has the ability to publish the result directly to your FTP server or to many weblogs website.
