Opencast

Opencast as an automated recording tool

The goal of the Opencast system at the University of Bremen is to provide an infrastructure for the automated recording of lectures and other events and their delivery in Stud.IP.

Currently many rooms at the University of Bremen are equipped with permanently installed recording technology for Opencast. The technology includes a camera with zoom and pan function, a recorder for simultaneous recording of video camera, beamer signal and sound, and a media control system.
 
 The media control touch panel is used to start, pause and stop recordings and to control the camera image via a selection of presets (lectern, panel 1, panel 2, stage, etc.).
 
 In the following, we will give you step-by-step instructions on how to plan and make recordings.

Opencast Aufzeichnungen planen

When you schedule your lecture recordings in Stud.IP, the event data (title, room, time of the session to be recorded, name of the organiser) are transmitted to the respective recorder in the lecture hall. This is the only way the recorder can know who you are and to which event in Stud.IP a recording belongs.

 

I.) First click on the "Opencast" tab. (1)

II.) Click on "Schedule Recordings" on the left. (2)

An overview of your lecture dates will appear.

On the right side of the overview, you will see the status of each appointment and available actions in the form of the following icons:

  • A recording is scheduled. (3)
  • No recording is scheduled yet. (4)
  • The date is in the past - recording is no longer possible or recording is completed. (5)
  • Schedule the recording of a single date. (6)

III.) Click on the blue camera icon (6) to schedule a recording.

IMPORTANT: Complete scheduling at least half an hour before the start of a lecture appointment. The recorder will not record otherwise. This also applies to cancellations.

You will receive the success message "Recording has been scheduled". (7)

Two new icons will appear next to your scheduled recording.

IV.) Via the circular arrow (8) you can update the metadata. Via the trash can icon (8) you can cancel the recording scheduling.

As the organizer, you are responsible for the content and information recorded during a recording. 
For this reason, we provide you below with the basic legal requirements that must be observed.

I.) If you have scheduled your recordings in Stud.IP in Opencast, the recorder belonging to your event will be set to standby mode at the start time of the session (e.g. at 10:00) in the respective lecture hall. The media control will only indicate the recorder's readiness to start the scheduled recording via a green light.(1)

II.) To start the actual recording, select the Recording tab on the media control.(2) Authorize the recording by entering your PIN (you will receive this from ZMML after logging in). The lamp above the media control now lights up red, signaling an active recording.(3)

III.) Use the pause button to pause the recording.(4) Click on record to resume the original recording.(5)

IV.) Use the stop button to end a recording (prematurely).(6) ATTENTION: Stopped recordings can no longer be continued. In this case you have to start a new recording, which cannot be assigned to your event automatically. In this case, please contact the ZMML.

If you do not stop the recording manually, your recording will automatically stop after 120 minutes.

V.) If you ever forget to schedule a recording in Stud.IP, you can also perform ad-hoc recordings. Enter your PIN and start a recording. The lamp will now light up red. In order for the recording to be assigned to you and your course in Stud.IP, please write an e-mail to the ZMML. Ad-hoc recordings are not automatically published to prevent misuse by third parties.

VI.) Click on the preview images to select a possible camera perspective.(7) The lecture hall camera will automatically zoom and pan to the specified position. In the HS-2010 lecture hall, you also have a live preview image of the camera.

Depending on the length of the recording, it takes several hours to process the video materials and make them available in Stud.IP.

I.) As soon as your recordings have been processed by the system, they will be available for preview in your course in Stud.IP in the Opencast tab.(1) 

II.) You can:

  • Use the Feedback button to send an email to technical support specifying a video. (2)
  • Make your recordings visible / invisible. (3)
  • Open the editor to edit your recordings afterwards. (You can find a tutorial about the editor here) (4)
  • Delete your recordings. (5)

ATTENTION: permanently deleted recordings cannot be restored.

Note: The live streaming and recording functions are coordinated to be usable simultaneously.

Livestreams

What do you need to do if you want to stream your event with Opencast?

II.)  Automatic streaming with Opencast is not available in all rooms of the university. Currently the following rooms are equipped with recording technology: see right side.

For further information on equipment in rooms at the University of Bremen, see the website of the of the media office.

In order to start an automatic livestream for your event, the room must be booked for the corresponding period for the event in Stud.IP.

 

I.) You start the live stream by selecting the tab Recording on the media control within the time booked for you. Authorize yourself by entering your PIN (you will receive this from ZMML after logging in). The lamp above the media control now lights up red, indicating an active live stream.

II.) You can pause the livestream by clicking Pause. Click Record to continue the livestream.

III.) Stop the livestream (and the eventually scheduled Opencast recording) at the end of your event by tapping "Stop recording" on the touch panel.

Note: Livestreams only work in the period booked on Stud.IP. Example: If you have booked the large lecture hall from 10:00 - 12:00, you can start the livestream at 10:00 at the earliest and it can only be viewed on Stud.IP until 12:00 at the latest.

We have now implemented the possibility for you to activate a live chat in the livestream plugin of your Stud.IP course. If you want to use the live chat for questions from the students, please keep in mind that the livestream has a time delay of about 7-11 seconds for the viewers.

In the Livestream window of your course, select Enable Livechat to use this feature.

 

 

The diversity of Opencast

Opencast is a free, open source software-based application that maps the complete lifecycle of lecture recordings. The process chain of Opencast includes the recording of video and audio in the lecture hall, the further processing and management of the data and the delivery of videos on media platforms and the learning management system Stud.IP.

More information about Opencast can be found on the official project page.

The modular structure of Opencast allows you to use individual components in other contexts.
 

  1.  Opencast as a complete process chain for automated recording in event rooms technically equipped for this purpose.
  2.  Opencast Studio as a stand-alone application for recording screen, webcam and microphone (screencast)
  3.  Opencast Plugin in Stud.IP for uploading and managing lecture recordings and any other video sources.


 The differences and similarities between Opencast, Opencast Studio and the Opencast Stud.IP plug-in are explained below.

Opencast Studio

Opencast Studio a simple, web-based application for screen, microphone and webcam recording.  With Opencast Studio you can produce individual screencasts in your home office or record entire lectures in the lecture hall. A microphone with good sound quality is essential for a successful recording. For face-to-face recordings in the lecture hall, we recommend the use of a Bluetooth headset so that you are not restricted in your freedom of movement.
 
 You can access Opencast Studio via cast.zmml.uni-bremen.de or directly in Stud.IP in your course in the plug-in Opencast under the item "Record video".  [More Informations]

Opencast Plugin in Stud.IP

The Opencast plugin in Stud.IP is the central interface for uploading and making your videos available. Here you can find your automated lecture hall recordings and deposit the screencasts created with Opencast Studio. [More Informations]
