Video, sound, and SWF movies
Adding video and sound effects can turn an otherwise dull site into something engaging and memorable. Flash Catalyst supports video files with the .flv and .f4v filename extensions and audio files with the .mp3 filename extension. Flash Catalyst does an excellent job creating fades and movement, but you can also produce more complex animation using other Adobe Creative Suite tools and then publish the movie as a SWF file. The SWF file is imported as an asset in your Flash Catalyst project. You can then use interactions to control the playback of your SWF content, including playing and stopping at a specific frame in the movie’s main timeline.
