Once again, Google is testing video carousels in desktop search - we saw it a bit over a year ago, we saw it in knowledge panels 1.5 years ago and it is often seen in mobile results. But it seems like Google is testing showing these video thumbnails in a carousel format for top news and other search boxes on desktop again.
Eric Hedekar and Jon Henshaw both saw different variations of them yesterday.
Eric posted on Twitter this video carousel box:
