The popular photo-sharing smartphone app now also will  handle 15-second videos, and include an image stabilization feature for iPhones that “will change video forever,” Instagram CEO Kevin Systrom says. In a brief demonstration at the announcement today, he showed how the process, called Cinema, can eliminate the shakiness that characterizes videos made from hand-held smartphones. In addition, Instagram will have 13 filters designed to help users enhance and edit images. “We’re still committed to making sure you have control over all of your content,” he says in a blog post. “Only the people who you let see your photos will be able to see your videos. And as with photos, you own your videos.” The initiative will help Instagram compete with Twitter‘s Vine video sharing. Some 130M people use Instagram. The new apps for iPhones and Android powered phones are available today. Facebook paid $1B last year to acquire Instagram.
