If your primary content is video's, then a carousel with thumbnails and no autorotation may be a very good UX element. You can't play multiple videos at the same time so showing extra full sized videos via scrolling is out of the question. Go to any video sites (i.e. YouTube, Vimeo) and you'll see that they all have what's effectively a carousel.
