Video is the most challenging multimedia content to deliver via the Web. One second of uncompressed NTSC (National Television Standards Committee) video, the international standard for television and video, requires approximately 27 megabytes of disk storage space. The amount of scaling and compression required to turn this quantity of data into something that can be used on a network is significant, sometimes so much so as to render the material useless. If at all possible, tailor your video content for the Web.
