Twitter has announced Vine, a new video app for the iPhone and iPod Touch that could spell trouble for other apps that describe themselves as the "Twitter of video."
Vine allows users to create six-second videos that play in an endless loop similar to GIFs. You can see examples on Twitter's blog.
"Like tweets, the brevity of videos on Vine (6 seconds or less) inspires creativity," Twitter said.
Users can download the Vine app from the Apple App Store. It's not necessary to have a Twitter account in order to use Vine, but Twitter says having one speeds up the process of signing up.
