A general term used to describe activities that occur within an Opencast system including Series and Events.


Events refer to a single episode or lecture that is recorded or uploaded. Typically they belong to a Series (see also Series section), however there can also be ad-hoc recordings that do not belong to a Series. You can access the Events page from the Main Menu > Recordings > Events.

Ad-hoc events

Ad-hoc events that occur spontaneously and may or may not belong to a Series. An example of an adhoc recording may be a recording of a dissertation practice or a recording of an unplanned meeting. Note: Not all capture agents support ad-hoc recordings. Refer to the capture agent’s manual to find out if it has this capability.


A Series is the equivalent of entire course and typically contains multiple Events (see also Events section) that occur across a defined period of time. You can access the Events page from the Main Menu > Recordings > Series.
