deploying kaltura at vancouver island university
DESCRIPTION
In this session, I share Vancouver Island University’s experience deploying a video streaming solution (Kaltura) locally on our campus. Kaltura is very similar in functionality to the popular video sharing site YouTube, however in our instance all of the content is stored locally on university servers and authentication is linked to local user accounts. We have also taken strides to integrate Kaltura with other online learning environments including Blackboard Collaborate, Desire2Learn, Mediawiki and WordPress. Kaltura allows both faculty and students to upload video content which is optimized for accessing in a web browser or on a mobile device. We are just starting to see some of the innovations coming through from our faculty as the service takes off. I will share some of the innovations and applications of video in education we have experienced thus far and reflect on some of the hardware, software and technical concerns our users are experiencing.TRANSCRIPT

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
