3 Click the Settings button The Flash Video Encoding Settings dialog box opens, as shown in Figure 11-10

Figure 11-9: The Flash video encoder is designed to convert video in nearly any format into the Flash video format

Figure 11-10: The Flash Video Encoder Settings dialog box includes five different tabs with video setting options

4 Click the Encoding Profiles tab and choose a Flash encoding profile The later the version of Flash, the better the encoding looks and the faster it plays, but here s the trade off: Not everyone has downloaded the latest version, so an earlier version may mean fewer visitors have to download the player to view your video Because Flash is such a fast and easy program to download, the latest version is generally the best choice though 5 Click the Video tab and specify additional video settings a Make sure Encode Video is checked The video codec (which controls the compression of the video) is set automatically based on the Flash version you selected in the Encoding Profiles Select Deinterlace only if you re encoding video that s interlaced, such as video captured from a television or VCR Video that s already been encoded in a format like Windows Media doesn t need to be Deinterlaced b Set Framerate to the lowest setting that will look good to achieve the fastest download time If you re encoding a video that has lots of action, you need a higher frame rate, ideally 24 or better, or your video will lose details and look fuzzy in places If you re converting a video, such as a Windows Media file that s already been encoded, your best option is to choose Same as Source to leave the framerate unchanged c Set the Quality to the lowest level that still looks good to get the fastest download times Use the slider under the preview window to move through the frames of the video to see the effects of your settings 6 Click the Audio tab to adjust audio settings Under the Audio tab, adjust the Data rate Again the lower the number, the lower the quality but the faster the download If your audio has only a single voice, you can set this quite low, and it ll still sound good If your audio file has music, special sound effects, or other multifaceted audio, set the Data rate to at least 96 kbps (kilobits per second) 7 Use the Cue Points tab and insert cues in the file that make it easier for someone using the file to jump to a particular section 8 Use the Crop and Resize tab to make the file physically smaller or larger Note that trying to increase the file size of a video can result in a severe loss of quality 9 After the settings are complete, press OK The Flash Video Encoder Settings dialog box closes, returning you to the Flash video encoder 10 Click Start Queue to begin the encoding process

This process can take several minutes, even for a very short file A small preview window in the bottom-right corner of the Flash video encoder enables you to watch the encoding process in action When the encoding process is complete, the Flash video encoder has created a copy of the video file in the FLV Flash video format

Java is a programming language, similar to Basic, C, or C++, that you can use to create programs that run on a computer What makes Java special is that it can run on any computer system and can display within a browser If you create a program in another programming language, you usually have to create one version for the Macintosh, another for the PC, and a third for Unix But Java, created by Sun Microsystems, is platform-independent, so developers can use it to create almost any kind of program even complex programs, such as a sophisticated game or even a word processing program that works on any type of computer without the user having to customize the code for each platform Another advantage of Java is that the program (dubbed an applet) can run within a Web browser, allowing the program to interact with different elements of the page or with other pages on the Web This capability has made Java popular on the Internet because it provides a way to add sophisticated capabilities to Web pages irrespective of the operating system the Web browser is running on You can embed Java applets in Web pages, you can use Java to generate entire Web pages, or you can run Java applications separately after they download
