Video Analytics
Full list of metrics https://mediawiki.viu.ca/wiki/VIUTube_Tracking_Analytics
ShortcomingsUtilities only available to KMC admins• Analytics • Uploading of captions• Clip trimming
Missed analytics • Metrics on access per device• Flavour served
Live streaming• Live streaming in flash only (in current version-CE 5.0 )
Mediaspace (KMS – VIUTube)• Not mobile friendly?
Lack of video annotations• Add text, links and hotspots over video in order to add information, interactivity
and engagement to videos
Currently investigating
Mobile Capture Cart• Cart system containing all
components necessary for capturing lecture
• Can be wheeled into any venue
Swivl• Motion tracking camera • For iOS and soon larger cameras

Video and copyright • Interesting questions arising over how we deal
with video found on publisher CDs• Many useful resources on old physical media
which could benefit from streaming
