  VP9 is a **video format**. Another example is H.264.
  
  WebM is a **container format** that VP9 goes into. It is equivalent to the MP4 container format for the H.264 video format.
  
  libvpx is a **video encoder** (or **codec**) which outputs the VP8 or VP9 video formats. Another encoder example is x264 which outputs the H.264 video format.
