          <h2>Your FFmpeg Setup</h2>
          <p>FFmpeg is an incredible tool, but you need to know how your version of FFmpeg is configured and what you can do with it before you start using it. Typically each copy of FFmpeg is configured in different ways. Certain videos can't be encoded but they can be decoded and then encdoed into a different format.</p>
