How simple or difficult is it to create Flash video? I have MX2004, Educational

What’s the process like? Is it something where you create actionscript codes that calls up an mpeg to a Flash interface and then allows the movie to be played within a Flash animation? What are some good websites (tutorial or gallery) to visit that focus on Flash and online streaming video?

thanks so much! I can imagine taking an mpeg file from my music performance DVD and streaming it on my Flash website for self promotion. Or taking the mpeg of a client’s music video and fixing it so that the intro to his/her Flash site is the mpeg movie, controlled (somehow) by Flash Player
