Lecture recording & Live streaming
Record and broadcast lectures
Over 50 lecture halls at the University of Bern are equipped with a podcast infrastructure. This infrastructure and the Opencast software make it easy to record, process and publish lectures, conference talks and other events, and now also to broadcast them live. The words spoken and the image projected by the beamer (e.g. PowerPoint or Visualizer slides, websites, videos) are recorded or live streamed as standard, but not the person speaking. The recording can be post-processed before publication and finally made available in ILIAS or on the video platform «Tobira» with or without a download option, or integrated into a website. Live streaming takes place via ILIAS or Tobira (YouTube only in exceptional cases).
Subtitles & slide recognition (NEW)
Automatic subtitling for podcasts and videos
Since August 2024, subtitles get automatically created for all podcast recordings and videos uploaded manually to Opencast. We use the open-source AI application “Whisper” which is running on our own servers. Therefore and like the videos themselves, the subtitles are processed and stored on the university's own servers.
The subtitles in the following video were created automatically with Whisper and were not corrected afterwards:
Very accurate and editable
Our own extensive tests with recordings in German, English and French confirmed previous study results: The automatically recognized subtitles are generally very good, have low word error rates (e.g. Radford et al., 2022) and even Swiss German videos are translated well into German (Dolev, Lutz & Aepli, 2024). However, technical terms in particular are sometimes transcribed incorrectly. Such errors can be easily corrected using the video editor (manual in ILIAS).
Can be deactivated, but essential for people with hearing impairments
The automatically generated subtitles can be deactivated during publication so that they do not appear in the published video. This may be desirable if, for example, the subtitles contain too many errors. To guarantee accessibility and ensure that people with hearing impairments receive all informations, we recommend that you add subtitles to all your podcasts and videos.
Also new: text recognition of slides
Also since August, the texts of the slides gets automatically recognized. The associated search, which is also offered for subtitles, and the associated direct access to the video passages found makes it easier for students to rewatch those parts of a lecture that they did not understand.
Why Podcasts?
Reasons for podcasts
More and more students of the University of Bern are expressing the wish to have their lectures recorded. In its position paper on Good Teaching, the SUB (Student Representation) also advocates increased availability of podcast recordings. So, what are the advantages of creating and offering podcasts in university teaching? Below, you find a list with eight sound arguments.
1. Podcasts enable effective follow-up and self-directed learning
The learners can listen selectively to those parts of an event that they did not understand for the first time. In this way, podcasts enable self-directed learning at students' own pace. Owing to the rewind and pause functions, students have time to reflect, research, and take notes. Thus, they are able to process the content much more thoroughly than in the classroom lecture. This particularly applies to all students whose native language is not German.
2. Podcasts improve learning success if they are used in a sensible way and as supplements to lecture attendance
Many students value the opportunity to prepare for their exams with the help of podcasts. However, as the first surveys show, this method alone does not lead to improved learning success: only if the podcasts are used as supplements—and not as substitutes—to lecture attendance, an improvement of the examination performance appears to be taking place (see Spaeth-Hilbert, Seufert & Wesner, 2013; study at the University of Manchester, available here from minute 5:30). Therefore, it seems that only the combination of lecture attendance and the use of podcasts for post-session and exam preparation can lead to higher learning success. This fact should be pointed out to the students at the beginning of their lectures.
3. Podcasts fill the gap when either the lecturers or the students are absent
If the lecturer is absent, no lectures are cancelled, as the content of podcasts from previous semesters can still be accessed. Alternatively, these podcasts can also be pre-produced. In this way, the planned content is being processed despite the “missed lecture”, and the learning objectives are achieved. By linking these podcasts to tasks, self-tests, or exercises (e.g. on ILIAS), students are encouraged to become involved in effective learning activities.
Podcasts enable students to take part in lectures even when they cannot attend them due to family or professional obligations, illness, military service, or lack of space in the lecture halls.
4. Owing to the integration in ILIAS, podcasts hardly require any additional effort and can be edited before publication
If you would like to record your lecture, you can apply for a podcast-capable room and activate the option «Podcast» or «Podcast & Live stream» in CTS when registering your lecture. You will then find an Opencast series with the dates of your lecture in your ILAS course short time later. The recording and any live streaming will then occur fully automatically. After the lecture you can edit the recording in your ILIAS course (e.g. cut out breaks) and publish it. The final product is therefore under your control.
5. Podcasts enable interactive event formats in the following semester
Podcasts that have been recorded once and are still up-to-date in terms of content can be used effectively in later semesters. This can be done, for example, by instructing students to use these podcasts to prepare for the attendance phase of the course. As the knowledge transfer now takes place in self-study, theory may be deepened and put into practice in the classroom course. Further questions can be discussed in plenary sessions. Exercises with immediate feedback or cases may be dealt with in smaller groups. What used to happen at home (and often) in isolated individual work is now taking place through social exchange with fellow students and in contact with the lecturers. Detailed information about the teaching scenario "Inverted Classroom" can be found here.
6. Podcasts enable lecturers to enrich and supplement face-to-face events
Contents that cannot be discussed in depth in the classroom may be made available in the form of podcasts. These podcasts can be used, for instance, to ensure that all students have the same level of knowledge before the event begins.
7. Podcasts facilitate the didactic and content-related development of one's teaching activities
Podcasts display and reflect a teaching situation and the lecturer's teaching methods. Consequently, self-evaluation and feedback measures can take place, possibly accompanied by didactic counselling. The team of the Learning and Development Unit will be pleased to support you.
8. Podcasts allow more flexible study models and the integration of people studying at a distance
Owing to the podcasts, knowledge transfer can take place regardless of time and place. As a result, students can decide for themselves when and where they want to listen to a lecture. In addition, it is now possible to involve students living far away in events.
Live-Streaming
Live streaming option
Since September 2021, live streams can be broadcasted from all podcast lecture halls. The transmission of projector screen, lecture hall audio, and any potential camera feed occurs with a delay of approximately 20 seconds, either via ILIAS (standard for lectures) or Tobira. Broadcasting to YouTube is only possible in exceptional cases. In ILIAS, communication with external participants is possible through an integrated chat.
Features of the live stream service
- Live streams can be ordered identically to lecture recordings (via KSL or using the provided form, see Procedure).
- A live streamed event is always also recorded. The recording can be edited and published afterwards as usual.
- Live streams transmitted on Tobira can get embedded on your website. The subsequently published recording appears in the same embedding window.
- There is no monitoring of the live stream. If the live stream is interrupted, the focus is on securing the parallel recording. A restart of the live stream is not possible.
Further notes
- In the case of events or conferences, a declaration of consent must be obtained from all speakers. This declaration must not only include the live stream but also the recording and any publication (e.g. on the institute or conference website).
- In case of breaks, a break slide with reference to the later continuation of the live stream may be useful. Templates for this can be found below.
- Whenever the spoken word is not suitable for live streaming (e.g., before the event, during breaks), turn off the microphones or set them to «mute».
- Don't forget to turn the microphones back on after such brakes.
- If you want to open the live stream on the presentation computer (e.g., to use the integrated chat) make sure to mute the audio of the live stream. Otherwise you risk unpleasant audio feedback.
Procedure
Way to your lecture recording or live stream
In order to record or live stream a lecture, the room must be equipped with the necessary infrastructure (see «Equipped Rooms»). You should therefore ask for a suitable room when making your room reservation. Alternatively, two sets of mobile podcast equipment can be borrowed for the purpose of recording one-off podcasts.
1. Reservation
You can reserve a podcast-capable room either directly in CTS/KSL when registering your lecture or at one of the decentralized reservation offices.
2. Order a recording / live stream
Two options are provided here. If your event is registered in CTS and you would also like to have an ILIAS course, then activate the option «Podcast» or «Podcast & Live stream» in CTS when registering your lecture. You will then find a «Opencast Series» in your ILIAS course shortly afterwards. In all other cases, please fill out the order form at an early stage. The processing time is 2 working days for a single recording, 5 working days for multiple or repeated recordings.
3. Recording / Live streaming
The recording and an eventual live streaming takes place automatically. When presenting please use the microphone and, if possible, the HDMI port of your notebook for your presentation. Alternatively, we recommend that you take your own adapter to HDMI with you. Live streams will be broadcasted via ILIAS or Tobira (via YouTube only in exceptional cases).
4. Editing
After the recording the videos need to be edited and published (also possible with live streams). You can do this in ILIAS or Tobira a few hours after the end of the lecture. You can cut the recording, remove breaks and add information. The effective publication takes place only after this step and again can take up to several hours.
5. Location of publication
The recordings are published either in your ILIAS course or in Tobira. You specify the location of publication either when ordering the recording or at a later time in ILIAS or Opencast. If you wish to live stream using YouTube, the publication will be on YouTube.
Detailed instructions for the most important steps can be found below.
Order
Ordering process
There are two ways to order a recording or live stream. These depend on whether your lecture is registered in CTS/KSL and whether you would also like an ILIAS course.
Option 1: "Lecture is registered in CTS/KSL, an ILIAS course is desired"
When registering the lecture in CTS, activate the option "Podcast" or "Podcast & Streaming". Before the semester, you will find a Opencast series in your ILIAS course. Here students can access your live streams and/or recordings.
If your course has already been registered in CTS, you can also set the options for podcast or live stream in hindsight. The best way to do this is to send an email to: podcast@unibe.ch
Option 2: "Lecture NOT registered in CTS/KSL or an ILIAS course not desired"
Fill out the appropriate order form for the lecture series or single lectures. The processing time is 2 working days for a single recording, 5 working days for multiple or repeated recordings.
Online form: Lecture series (only in German)
Online form: Single recording (incl. conferences) (only in German)
Report date adjustments
If the date, time or room of your lecture has changed, please let us know by sending an email to podcast@unibe.ch. In order to process your request correctly, we need the full title of your Opencast series.
Cancel
Cancelling recordings and live streams
If you do not wish to have a recording or live streaming for individual sessions of an event for which a podcast or live stream has been scheduled, please proceed as follows:
- Faculty of Medicine: Lectures of the study programme Human Medicine which do not get recorded are already marked with (oP) in the title («ohne Podcast»). If other lectures are not to be recorded, please report them to studium@meddek.unibe.ch, at the latest five days before the lecture. By default, all lectures in the academic years 3-6 are recorded.
- All other faculties:
- Cancellation of recording series: By switching the option «Podcast & Live stream» in the CTS/KSL course settings to «No» (under «Room Requests») you cancel all recording and live stream dates of a course. After receiving the confirmation e-mail, the scheduled dates can also be deleted in the Opencast series in ILIAS. If you delete only the series, the scheduled dates will remain and will be recorded.
- Cancellation of individual recordings: No active measures are necessary. Just forgo post-processing and publication, and delete the recording afterwards. Alternatively, you can also delete the unwanted appointment shortly beforehand.
