This is a poster movie.
When you click it, it turns into a movie with a controller.
The movie autoplays. When it's done playing, it turns back into a poster.
You can repeat the process as often as you like. Try it...
You can use this technique to embed multiple movies in a Web page. The page loads quickly because the posters are small compared with the movies they link to. Memory requirements are reduced because only one movie is loaded at any time; when it's done playing, it turns back into a poster and frees memory.
The poster movie is embedded in the page with the attribute CONTROLLER="false". Here's the HTML: < EMBED SRC=poster.mov HEIGHT=256 WIDTH=320 CONTROLLER=false >
Note that the poster is 16 pixels taller than the movie, so it occupies the same space as the movie plus controller.
The poster turns into a movie when you click it because a Movie URL and a TARGET have been added using Plugin Helper:
Note that the poster also has CONTROLLER=false embedded using Plugin Helper.
The actual movie autoplays because AUTOPLAY=true has been added to it using Plugin Helper. It has a controller because that's the QuickTime default. (You don't need to specify CONTROLLER=true using Plugin Helper, and you shouldn't.)
The movie turns back into a poster because it has an HREF track with a single sample at the end of the movie: A<poster.mov> T<myself>
(Creating an HREF Track is described in Chapter 13, "Text! Text! Text!")
That's all there is to it...
