Because the poster frame and the movie have the same <height> and <width> attributes, the movie will seamlessly appear where the poster frame used to be. Tip: As with any graphic on any Web page, you or your Web design software should remember to upload the newly created poster-frame graphic. You can use Captain FTP for this purpose, for example. Posting a Movie on Your Own Web Site Optimizing Online Movies This chapter covers the fundamentals of putting your iMovie on the Web, but there's a lot more to online video. The next step is tweaking the movie fles themselves to optimize them for online viewing. When you put your movie on the Web, millions of people can see it, which is won- derful. Unfortunately, some of those people connect to the Internet using dial-up modems, some use high-speed broadband connections like cable modems and DSL, while the luckiest connect through such ultrafast pipes as T1 lines. If you had the time, hard drive space, and inclination, you could actually create different versions of your movie, one for each of these connection speeds. For instance, a cable modem owner would see a high-resolution, 320 x 240 movie playing at ffteen frames per second. His neighbor, dialing in on a 56 K modem, would see a 240 x 180 version (an alternate version) playing ten frames per second. Each person would see an appro- priately sized rendition that would be as large and beautiful as that kind of Internet connection would permit. (How does a Web page know which version of the movie to transmit? The answer lies in the QuickTime panel of System Preferences. If you click the Connection tab, you'll see the list of different connection methods--modem, DSL/Cable, and so on. You're supposed to choose the one that connects you to the Internet. When you click a movie on a Web page, the Web page computer actually asks your Mac what kind of connection speed you've got. Your Mac responds with whatever setting you've made in System Preferences.) Performing this kind of optimization is an elaborate feld of study that, as you can imagine, gets massively complicated. It requires, among other things, a program like Cleaner 6 ( The company's Web site is worth visiting if you're interested in pursuing this degree of customization. It's absolutely teeming with information about producing online video. Furthermore, Apple's own QuickTime Authoring Web site ( quicktime/authoring) has some excellent tutorials on these more advanced strategies. chapter13:moviesontheweb--andonthephone 331
