Hypervideos, consisting of media enriched and linked video scenes, have proven useful in many scenarios. Software solutions exist that help authors make hypervideos from media files. However, recording and editing video scenes for hypervideos is a tedious and time consuming job. Huge video databases like YouTube exist that can provide rich sources of video material. Yet it is often illegal to download and re-purpose videos from these sites, requiring a solution that links whole videos or parts of videos and plays them in an embedded player. This work presents the SIVA Web Producer, a Chrome extension for the creation of hypervideos consisting of scenes from YouTube videos. After creating a project, the SIVA Web Producer embeds YouTube videos or parts thereof as video clips. These can then be linked in a scene graph and extended with annotations. The plug-in provides a preview space for testing the hypervideo. Finalized videos can be published on the SIVA Web Portal or embedded in a Web page.

The growing number of elderly people combined with financial cuts in the health care sector lead to an increased demand for computer supported medical services. New standards like HTML5 allow the creation of hypervideo training applications that run on a variety of end user devices. In this paper, we evaluate an HTML5 player running an e-health hypervideo for the support of pelvic floor exercises. In an experimental test setting we compared the hypervideo to a primarily linear version regarding usability and utilization for self-controlled training. Our results show the hypervideo version leads to slightly more usability problems but facilitated a more active and individual training.

Due to their structure, hypervideos are well suited for different scenarios. Compared to traditional linear videos, they have advantages especially in e-learning and training, where the study matter can be fitted to the needs of the viewer. In this paper we present the SIVA Suite, an open source framework for the creation, playback, and administration of hypervideos. The SIVA Suite consists of an authoring tool, an HTML5 hypervideo player, and a Web server for user and video management. This framework has been successfully used for the creation of hypervideos in different use cases, e.g. a medical hypervideo training. It was evaluated in several usability tests and improved step-by-step since 2008.
