Whenever your query brings up a video, Google will now show you a silent six-second clip to help you decide if it’s actually a video you want to see. >This will work for the vast majority of videos on the web today — including, but not limited to, YouTube. Indeed, as Emily Moxley, Google’s director of product management for this project, told me, any video on the web is eligible for inclusion, though Google may not have a preview for some of the newest videos available yet because it takes the servers a bit of time to build the previews.
