Answers.Body: <p>It's worth noting in addition to @mcont's excellent answer, royalties for h.264 (the most popular encoder on the internet) are only applicable if you are charging viewers to watch, and then only when the viewer numbers go over a certain volume, or if you're charging per view only when the video is over a certain length. If your content is free to view then you won't need to pay royalties.</p>
