Vine today announced new support for higher-resolution video. Since launch, the video-sharing service has uploaded videos with a maximum resolution of 480p. An update to its mobile application will record and upload videos in 720p HD. The update will hit the iOS version of Vine in the coming days, with the Android version to follow at some point down the road. Vine is owned by Twitter and lets people record 6-second videos that are then played back in loops. Earlier this week, Twitter released an app called Periscope, which lets people broadcast live video from their smartphones.
