Digital video appears in most multimedia applications, particularly on the Web. Like audio, websites can also stream digital video to raise the speed of the playback. Flash, MPEG, AVI, WMV and QuickTime are some of the common digital video formats. By the way, most digital video is supported by browser plug-ins to play within Web pages. All the same, some user’s browser would have already had the plug-ins installed.
Within Web and desktop multimedia applications, animated components are common. By using mouse and keyboard, interactive effects allow users to engage with the animation action. However, the most widely used tool for creating animations on the Web is Adobe Flash. Desktop applications are also aided by Adobe Flash. By using Flash, designers can create FLV files and exporting them as SWF movies for users to operate. Further Flash also uses ActionScript code to achieve animated and interactive effects.
