Why is video important?

How important are the following course resources to you?
Lecture recordings are highly valued by students.
Lecture recordings are a safety-net for students: a second chance to go over difficult material, or catch up on missed lectures.
Video provides an important way of engaging learners in online and blended e-learning courses.
But video can also be complex to produce, manage and preserve.
Opencast Matterhorn...
… is a free, flexible, open-source platform to support the management of educational audio and video content.
Institutions use Matterhorn to produce lecture recordings, manage existing video, serve designated distribution channels, and provide user interfaces to engage students with educational videos.
Matterhorn is not itself a video portal (“mytube”).
Where is Opencast Matterhorn used?

ProcessingMatterhorn video processing is defined by flexible and powerful workflows which determine how the media is processed, and encoding profiles which define the formats (container and codec). You can write your own workflow to suit your needs.
Matterhorn uses ffmpeg and other open source tools to analyse and transcode audio and video.
For example a lecture capture workflow at the University of Cape Town:
1. ingest recording (audio, presenter/camera track, presentation/slide track)2. create working versions (mix in audio)3. hold for review and trimming4. normalize audio (adjust to reasonable loudness)5. create download MP4 versions at 360p (H264)6. create FLV streaming versions7. archive high-quality versions (720p/1080p)
DistributeYou can choose how to distribute (publish) recordings from Matterhorn (defined in workflows and encoding profiles)
