Vine did more than just fix some bugs in the latest Windows Phone update, they have finally added the ability to upload videos from your camera roll. Previously the only way to upload a video from the app would be to record a new one, but that has changed.
The capture screen will now have a new button for your camera roll in the lower left corner so you can select a video you want to use. Once a video is selected you will be able to pick which six seconds of the video you want to post. In addition you will be able to mix and match videos if you want to get a little more creative. The update is now live in the Windows Phone Store, so get to sharing your favorite six second clips.
This is the first update to Vine on Windows Phone since December, 2013.
