Shwup is a new service for creating videos based on your images and audio files. At its most basic Shwup is a place for creating collaborative private photo albums. As the creator of an album you can select the best images and create a video for the group. You can choose to share your videos privately so that only those you invite can see them or you can share your videos on Facebook, Twitter, or embed them into your blog.
