For lecture presentations and to make details visible, the video window can be expanded to full screen. While video is being played, a set of control buttons allow stopping, backing up, slow motion, and replaying. If an IBM M-Motion video adapter is not present, the video button will not appear. For most elements the visual database includes a view of the element itself and videos of common products or materials that contain the element. For most elements that react with air, water, acids, or base, video sequences showing those reactions are available on the disc.
Video is available either through the video button or via hot word in the hypertext.
