Body: <p>I was re-watching for the upteenth time <a href="https://www.youtube.com/watch?v=UGJV6cJkFcc" rel="nofollow noreferrer">this video</a>.</p>
  
  <p>10 seconds in, when they start performing, the effect I would like to talk about is evident: the band members seem to move as if the video was sped up, yet their movements are in sync with the song (look at the drummer and most noticeably the singer lips).</p>
  
  <p>It does not seem to me that they where filmed at a lower speed (i.e. also the song was being played slowly), so I am wondering, how can such an effect be obtained? Am I mistaken and the method is indeed the one I am discarding, or is there some more clever video editing process at play here?</p>
