Streaming Basics: Shooting Video for Streamingby Tim Kennedy January 12, 2001
Youve spent days in scripting, shooting your video, and editing. Your short will be the piece that people will be talking about on the Web for weeks to come. So you encode for streaming and out comes the most amazing
What went wrong? One of the first misconceptions about streaming video is that it is just an add-on. By that, I mean that many people think that you can take any video short and just "add-on" streaming at the end of the process. The Ins and Outs In this article, I am going to focus on shooting good video. Other than a little introduction to how streaming works, most of this information will focus outside of the computer. Many of these techniques apply to any good video production. Understanding the Limitations of Streaming Streaming is all about compromises. Your raw video content, with all its color, detail, and sound, consumes a pretty good chunk of bandwidth (information space). Take a close look at your television screen. You'll see millions of pixels changing every second: images streaking by. Now imagine you had to turn each pixel into data (information) and keep track of all those changes. When you stream that information, a computer is going to have to do the math to make all that happen. A computer is going to have to take your video signal, break that file into chunks of data (packets), and feed those packets down the Internet pipeline. A computer on the receiving end is going to have to put all that data back together so the user can see it. Well, that is kind of like trying to land a Boeing 777 in your back yard. If your back yard is the size of mine, the end results are not going to be too pretty. If you stream raw video, there is too much data for limited computer and network systems to handle. There is too much data to shove down that Internet pipeline.
