Following the recent debut of Instagram video, Twitter has updated Vine to version 1.3, adding a number of new organizational features that are designed to aid in content discovery. Vine now includes 15 channels in the Explore section plus popular and rising Vine videos. The app has also been updated with new camera tools, offering a grid view, a focus button to allow users to select the area of the video to focus on, and a ghost button that saves transparent frames from the previous shot. Vine posts can now be "revined" with a single tap, and protected accounts are also available. Vine can be downloaded from the App Store for free.
