Abstract:

One of the most exciting upgrades in Flash MX is the fact that you can now compress and playback video within Flash. In the previous version of Flash you could import but then could only export the video as a QuickTime movie. You did not have the ability to playback or compress the movie within Flash. If you want to incorporate video into your Flash movies, then Flash MX should be your tool of choice!
