The #Wikimedia Foundation’s multimedia team seeks community guidance on whether or not to support the #MP4 video file format on Wikimedia projects. “However, MP4 is a #patent-encumbered format, and using a proprietary format would be a departure from our current practice of only supporting #open formats on our sites – even though the licenses appear to have acceptable legal terms, with only a small #fee required.” https://commons.wikimedia.org/wiki/Commons:Requests_for_comment/MP4_Video
