NUVision Media Library and Upload Service

NUVision Media Library and Upload Service NUVision provides an easy method of streaming your media files within the VLE and from web sites. The system converts files that you upload, converting them to MP4 files that are of a suitable size and format to stream over the web. It also generates embed code that you can use to publish files in web pages. NUVision can only be used by University staff.

NUVision Overview NUVision provides a simple method of uploading and streaming existing video content. The main benefits are: Files are held on university file store Media files are converted to standard formats that can be played on most devices Files are streamed from the server they do not have to be downloaded Once files are uploaded and converted they can be made accessible to users by adding embed code to web pages and Blackboard items. The content is viewed in an embedded player. Uploaded files are placed into categories in an associated Media Library. Staff can view and search for content in their own categories. A wide variety of file types can be uploaded (Appendix 4), once uploaded they are converted into mp4 files. Up to 3 different qualities of mp4s are created to handle playback on mobile, standard playback and high definition. At present the system cannot handle videos that have been created without a soundtrack. Students only have access to a small number of Public categories. NUVision User Guide V2.6 2 July 2013
