Social network brings its current total of photography and video apps up to six in battle with Twitter’s Vine and Periscope

Facebook has launched another video camera app. Riff for the iPhone and Android allows collaborative looping video creation – a bit like Twitter’s Vine on steroids.

The free app allows one user to record a short clip similar to a Vine or Instagram video and publish it within the app or Facebook. Other users can then find and add to that clip with their own short clip, building a longer video that loops through.
