An Event in Opencast refers to a single lecture, training, or meeting that is automatically recorded or uploaded.

How to Edit Events

Metadata and Access Policies are being saved automatically when the cursor leaves the field or an option is selected.

How to delete Events
From the Event page you have the capability to delete a single or multiple events.

When events are deleted from the asset management layer of Opencast, their link to various publication channels will be lost, i. e. there will no longer be an easy way to un-publish them. It is therefore recommended to first un-publish the events in question. See the Processing section on how to start a task on an Event.

If processing is Paused, use the warning icon ( ) to open the Event's details workflow tab, where you can Retry ( ) or Resume (without retrying) ( ) processing.
How to stop Event processing

The comments allows you create, reply and resolve comments on a per event basis.

Comments indicators are displayed in the Actions column as follow:
- At least one unresolved comment on the Event

Use the Filters to find flagged events.
