Now, it's usually not quite that bad. A typical mini-DV handheld camera shoots video in a compressed format closely related to the JPEG format used for still photography. And that compresses the data by a ratio of about 5:1, or about 140,000 bytes per frame.
But how many frames are there per second? For decent video, about 30 frames. And that works out to over four megabytes per second. Even on cable modem or DSL, most website visitors won't be able to handle that kind of speed and still play the video as they download it. What's worse, if you did have multiple users doing that, you would go way, way past your alloted bandwidth and be charged extra by your web hosting company. Ouch.
So what can you do about it? Get realistic about the video formats you use. See "How do I add video to my website?" for detailed information on how to convert your video to formats that are practical for use on the web. And consider free video hosting services and BitTorrent, both of which are covered in that article.
