Web Site Development: Additional Website Components: Digital Video |
Digital Video is nothing more than translating
existing "analog" video [video stored on VHS tapes, 8mm tapes, etc] into a digital
format. The resulting file may then be used in a variety of applications. Usually one imports digital
video files into a presentation package such as PowerPoint or onto a web site.
There are basically two different "types" of digital video in
existence. The first type, called "file-based video", is of very
high quality. This type of video is mainly used when working with a
graphical presentation package like Microsoft PowerPoint. The limiting
factor of this type of video is its' file size -- anything clip longer than a
few seconds of video will not fit on a conventional floppy diskette. Thus,
to use this type of video, you would have to use a high-capacity storage device,
like a CD-ROM, to transport your video from place to place. This type of
video is not well suited for web delivery.

The second type of video is called "streaming video". Streaming video acts much like a TV broadcast -- when you wish to watch your video, a program called a "video server" breaks up your video file into little pieces called "packets". These packets race across the Internet one at a time and get reassembled on your computer in order. This type of video will appear to begin playing instantly, and the file size is generally small. Unfortunately, quality is sacrificed when using this type of video. The main use for streaming video is web delivery - this type of video is not suited for local presentations.

Both types of video may be generated through our new Video Digitization station at Instructional Technology Services. If you are interested in using this type of technology, please visit the Instructional Technology Services Center during normal operating hours (click here to look up our location and availability), or contact the Instructional Technology Coordinator (Craig Kapp, kapp@tcnj.edu) for more information.
Complete instructions on how to use our video digitization facilities can be found by clicking the icon below.
