It is strongly recommended that your video remain an external file and not
be embedded.

Progressive download versus streaming
One of the first questions you??™ll need to address when adding Flash video to your Web page is: How will
the video be delivered? The two core methods available are progressive download and streaming. Both
methods are alike in that they use external video files in .flv format in conjunction with a .swf file that
acts as a video player.
Progressive download begins playing as soon as the first segment has been received by the site visitor and
continues to download while the video is playing. Typically, the delay is relatively short, but there is often a
perceived delay. There is, however, a major plus for progressive download over streaming: you can host the
files on any kind of server. Because progressive download does not require a specialized server, such as
Flash Media Server (formerly Flash Communication Server), it is much less expensive to display.
You??™ll need to require at least Flash Player 7 if you use the progressive download method;
streaming video can use Flash Player 6 or better.
Streaming video, however, can definitely be worth the cost. Video begins playing almost immediately and is
more efficient for both the network in general and the viewer??™s computer specifically.
