What software is used to create the Animoto video on the home page?

I've been seeing a few videos like the Girl Effect on You Tube and the sales video on the Animoto homepage and wondered if anyone knew the software that was used to create them - are they just flash or is there a more user friendly software that someone can use to create a video like these.What software is used to create the Animoto video on the home page?Most likely after effects since it can do anything and is used in most professional visual effects production.
