Where did the people come from? I mean, I know you said they are from "the library", but there is also a new feature where additional assets may be downloaded.
Depending on what you have, it may be possible to achieve some rudimentary animation. But it would also likely require SnagIt. My thought here is that if the image of the person is just the person isolated on a transparent background, you may be able to use SnagIt to break it into segments, then use the segments in Camtasia along with Camtasia's animation features to make it appear the person is fully animated.
