Many, but not all, graphics from the Web had to be scaled or cropped before they made effective presentation materials. Although there are a number of ways that this can be accomplished, the most satisfactory in terms of quality was to use Adobe Photoshop 4.0. The quality of scaled images was much higher than was possible with other methods. The most difficult part about using Web-based multimedia in classroom presentations is finding the images in the first place. Having enough RAM to open Netscape, Astound, and Photoshop, plus a number of smaller programs at the same time made things much easier than they otherwise would have been.
Digital video requires a great deal of storage space.
Either a high capacity removable drive, or a CD writer will be needed if digital video is used. Iomega's Zip drive was found to be an excellent, reliable storage medium. Digital video compression was very time consuming, and generally must be done in batches overnight. Movie Cleaner Pro was excellent in this regard, but had one flaw. If a minor error occurred in one part of a batch process, the entire process was halted unnecessarily for user input.
