I support Anti-Bullying Week

With not much time available, and even less budget, we needed to produce some collateral that explained why we were supporting the Anti-Bullying Alliance's Anti-Bullying Week. Simple videos recorded on iPhone5, using VideoMicMe, enlivened by graphics from ABWeek, and a royalty free sounds track. Edited in iMovie. So how did I get the animated words superimposed on top of the video?
