Vine is a completely free video sharing service available for iPhone and many other mobile platforms that lets you take short six second videos to share with the world. Much like Instagram, Vine videos are in a square format and can be made from multiple clips. Many celebrities and comedians have found interesting and unique ways to share moments with Vine all over the world.
The point of Vine is to share moments as they happen, so that means you can't import existing video from your iPhone to create a Vine. Instead, you have to record Vines while you're in that specific moment. You can however save Vines that you want to complete later or add pieces to. This feature has made it possible for many Viners to get extremely creative. For instance, some Vine videos can take viewers across the world in a mere six seconds.
Vine videos can be shared instantly on both Twitter and Facebook. You can also embed Vines on other sites if you'd like. By default Vine videos are created to loop over and over, which is what they will do in the Vine timeline and when viewed on many social media sites.
After Vine was initially released, many competing services such as Instagram made it possible to upload short videos. Instagram tried to set the bar slightly higher by allowing users to upload a full 15 seconds of video instead of the shorter 6 seconds that Vine allows. However, part of the draw to Vine is how creative people can be in such a short expanse of time. Because of that, many people still prefer to share short videos on Vine than other competing services.
