AnnoVid allows you to review and annotate videos on any web page. You can share your annotations with your friends and colleagues. The extension integrates into web page workflows. It lists available video elements of a page within the browser's sidebar and allows you to select a video for annotation. AnnoVid does not only work with a limited set of platforms like YouTube but it works with any platform and web page containing videos as HTML5 video elements. This can be a public platform or your company's intranet. Flash videos are not supported.
