We have tried to include video on Flickr gently. Videos will show up anywhere photos do (in search results, photostreams, Explore, RSS feeds, etc) but they won’t play automatically. On the page that displays a video, it’s set to play automatically by default, but there’s a setting available in Your Account if you’d rather start it playing yourself. So, the only difference is that you will also be able to click play on some of the images you see.
