Processing Matterhorn 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).

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 trimming 4. normalize audio (adjust to reasonable loudness) 5. create download MP4 versions at 360p (H264) 6. create FLV streaming versions 7. archive high-quality versions (720p/1080p)
