Back in 2012, social video-sharing app Viddy was riding high, signing up tens of millions of users, raising big funding rounds and pitching itself as the ‘Instagram for video’ – with prominent musicians enticed by the buzz too. Then came a fall as Facebook clamped down on some of the viral sharing that had fuelled Viddy’s growth. Now in late 2013, Viddy has rebranded as Supernova, and although it’s continuing development of the Viddy app (for now), it’s also working on some new mobile apps. One is called Epic, and focuses on slow-motion video, capturing two-second videos and stretching them out to up to eight-seconds while looping them. It’s like a slo-mo Vine, in other words. The second app will be a Snapchat-style visual messaging app called Clique, where people ping images back and forth while adding stickers and text. Both seem a bit like fast-follows, but Supernova is hoping they’ll be a hit with younger smartphone users.
