Wikimedia is kind of different from other websites to upload videos. Wikimedia accepts and encourages uploading video files on Commons. As an example the image that we going to use must be freely licensed. We can’t just download the image from Google or other sources and just upload it. On the other hand, the video that we should format is better to be WebM or also OGV could work as well.
User Generated Content (UGC) is re-shaping the way people watch video and TV, with millions of video producers and consumers. In particular, UGC sites are creating new viewing patterns and social interactions, empowering users to be more creative, and developing new business opportunities. To better understand the impact of UGC systems, we have analyzed YouTube, the world’s largest UGC VoD system.
