Open Source software for 2D graphic animation like this:

Can someone suggest me a good software of graphic 2D animation, for animating images, and also a software for insert some more or less static text during a video? I'll post an example of my animation what should looks like, it start at 1:05 minutes in the video; while the text is for example the name of the people who are speaking :)
