Preparing Movies for HTTP Streaming

In preparing a movie for HTTP streaming, it’s important to get the movie’s data rate relatively close to the bandwidth of the network connection you expect users to have. If the movie’s data rate is higher than the available bandwidth, users will have to wait until a certain amount of the file has downloaded before it starts playing (Figures 16.1 and 16.2). If a movie’s data rate is only slightly higher, this wait may be quite short—perhaps no more than a few seconds, which for all purposes is streaming.

Figure 16.1. When an HTTP movie is being downloaded for viewing on a Web page, the shaded portion of the slider represents the amount of the movie that has been downloaded. The higher the data rate and the longer the movie, the more data that needs to be downloaded before the movie will play.
