Adobe® Visual Communicator® 3 offers hundreds of customizable graphics, music and special effects to create video presentations that look like a television newscast. When presenting in front of a backdrop, users can digitally replace the background with an image or video. The teleprompter allows users to speak confidently without missing key points or memorizing lines. Video presentations can be delivered via email, the Internet, CD, DVD, or live over a Channel One Closed-Circuit System. Visual Communicator will be available for Windows platforms this summer, but you can download a free preview of the software now. Note: The Visual Communicator 3 preview is available for use for a limited time and will expire on August 31, 2007. This is not a final release and for this reason official technical support is not provided.
