Now you need to prepare the movies to play when the buttons are depressed. You'll import one video file and encode it in FLV format; the other movies are already in FLV format for you. Then, use the FLV playback component controls to link the appropriate movie file with the frame for each button, and to turn autoplay on or off. Finally, you'll use ActionScript to move the Timeline to the appropriate frame when each button is clicked. About Importing Video When you import video, you can choose to embed it, which places the video in the Timeline so that it becomes part of the Flash document, or load it externally, so that it remains a separate file. Embedded video works best for smaller video clips without audio tracks; if you're using video clips longer than 10 seconds, load external video files and download the video progressively (so the viewer can watch it as it is downloading) or stream video using Flash Video Server. Importing Video Files You can import video files into Flash and convert them into FLV files at the same time. The Import Video wizard creates an FLV playback component, which contains the video file and the skin, or controls, that you've selected. 1. Select frame 1 on the Video Player layer. 2. Choose File > Import > Import Video. 3. In the Import Video wizard, select On Your Computer, and click Browse (Windows) or Choose (Mac OS). 4. In the dialog box, select Penguins.mov from the Lesson09/09Start folder, and click Open. Click Next or Continue in the wizard. 5. From the deployment options, select Progressive Download From A Web Server. Click Next or Continue. Note Progressive download lets the video file play as it downloads to the viewer's computer.
