Taking stock of video and audio: look to clip media for the perfect sound bite or video segment for your presentation

Article Abstract:

Clip media, both audio and video, is now widely available through desktop publishing firms and is a useful tool in creating compelling business and training presentations. Many organizations now offer prepackaged clip-video and audio collections priced from $50 to $399. The Publishing Factory offers four two-hour video collections at $89 each, and seven 30-minute audio for $15 each. Clip-audio collections cover a wide range of musical types from country to classical, and also contain isolated sound effects such as drumrolls and heartbeats. The video collections usually include a variety of nature and business scenes, people, animals, cities and sporting events. In the past, this type of footage was only available through stock agencies at much higher cost. Alternatively, users could develop their own, but it requires special equipment and a certain degree of talent to be able to do so successfully.

Displays of wealth

Article Abstract:

High-end color monitors, which can cost between $10,000 and $20,000, may be a wise investment decision, but only if users know what criteria to seek in a monitor. Red, green, blue (RGB) monitors contain three electron guns, each of which produces one color. Potential monitor buyers should examine monitors' convergence, which is how well the three guns are lined up. Misconvergence creates a fuzzy, shadowed image. Better quality monitors also tend to have better quality phosphors. Also, monitors usually have one of three color temperatures: 5,000 Kelvin, 6,500 Kelvin and 9,200 Kelvin. The choice of a temperature is largely up to individual preference. In addition, calibrators are available to measure accuracy of monitors. Basically, users would do well to choose the monitor that gives them as much flexibility as possible in their price range.

Distinguished panels: LCD panels make it easy to project your on-screen presentation to a large audience

Article Abstract:

Liquid crystal display (LCD) panels for overhead projectors enable users to project images from their computer screen in a way that is reliable and affordable. LCD panels employ the technology found in laptop monitors. They are easy to connect to a Macintosh or IBM PC or compatible, come with the necessary cables and let users view images on the monitor while they are being projected from the panel; in addition, their controls for contrast, tint and brightness are simple to use. LCD panels are distinguished by the number of colors they can display. For example, Apollo's Vision 16.7 generates 16.7 million colors, while most others range from 24,000 to 614,000. Users can choose to display fewer colors than the maximum number to improve speed and crispness, and most systems offer multiple display formats.
