Self-recording with zoom in lecture halls or seminar rooms

Self-recording can also be used to provide recordings where automated recording is not available or where the instructor's camera image is to be recorded in addition to the beamer signal.

In these cases, a Zoom meeting is created and recorded. Afterwards, you upload this recording to ILIAS and make it available (see Phase 3 Provide recordings).

In all lecture halls where a lecture is available as a live stream with Zoom (cf. Scenario: Streaming Lecture (Beamer/Visualizer) with Chat), Zoom can also be used to create a recording of the lecture. This is also possible in seminar rooms. The prerequisite for this is that a stable Internet access is available. If possible, the internet access should be wired via LTA access. Where such access does not exist, a restriction in the reliability of the Internet connection must be accepted and the KIT WLAN must be used.

Students may not be recorded for privacy reasons. This applies to video and audio. This would require written consent and administration for subsequent, targeted handling of individual deletion requests. Therefore, it is not possible to record parts in which students can be seen or heard. Split into a lecture portion and discussion portion and record only the lecture portion. In Zoom, the recording can also be paused for several discussion parts in between. The individual sections recorded in this way are available in one piece at the end.

Why no blackboard?

Instead of the blackboard, the Visualizer is used. This means you can write on paper and show this on the beamer and in the livestream in Zoom. A blackboard image would have to be filmed manually with a camera. There is a separate scenario for this.

Your own laptop as media control!

Unlike before, the control is primarily no longer done with the media control of the lecture hall, but on your laptop. There you create the desired display from the Visualizer image, your own content such as a presentation and elements from the Zoom return channel such as the chat. You output this presentation once to the beamer in the lecture hall and release it in Zoom as a stream. To make this possible, you get the Visualizer signal, the webcam and the microphone via USB cable. The output to the beamer is done via HDMI cable. Switching between different contents in the event is then done during the event on your end device in Zoom.

What content is possible?

Basically, you can use anything that can be displayed on your end device. This can be e.g. PowerPoint presentations or other screen contents. The image of the Visualizer is made available to you via USB as a second webcam. You can select this as a second webcam in Zoom in the screen sharing and thus show it in the Livestream as well as on the beamer in the room. At the same time, you can show yourself in the stream using the webcam.

Is it also possible to record?

In principle, this is technically possible without further hurdles. However, the requirements of data protection must be observed. Students must not be recorded. This would require written consent and administration for the later, targeted handling of individual deletion requests. Therefore, it is not possible to record parts in which students can be seen or heard. Alternatively, you can record the lecture section and pause the recording in Zoom for several discussion sections in between. The individual sections recorded in this way are available at the end as a video file in one piece without postprocessing.

Lecture halls without suitable microphones

In a few lecture halls without a microphone system, you will need a suitable wireless microphone of your own so that students participating online can hear you. There are recommendations for this in the documents on technical implementation and device recommendations.

Notepad Zoom enable

Microphone icon (bottom left): One to several USB devices appear here. Select them one by one and check for which one you see a green color in the microphone icon when you tap on the microphone with mute removed.

Also select the HDMI output of your laptop as the loudspeaker, so that contributions from students connected online can also be heard in the room.

Camera icon (bottom left): Select the webcam built into your laptop or the additional USB webcam you want to show. The camera device for the Visualizer also appears here, but is not selected here.

Share Screen (bottom center): Here you share different content to be shown in the Livestream, or switch between them. For example, you can share your entire screen, a window of an application or documents under the Visualizer as content of the second camera. The sound and the screen sharing are recorded in each case.

HDMI output to the projector: The projector is connected via HDMI. Depending on your system and requirements, you can decide whether it should display the contents of your screen 1:1 or be used as a second screen.

Tip Displaying a PowerPoint presentation in a window instead of full screen mode

A PowerPoint presentation can also be played back in a window if, for example, other content such as the chat history from Zoom is to be displayed on the beamer in addition to the presentation. To do this, select the setting "View through an individual (window)" under "Set up slide show" for "Type of presentation". The presentation will then be displayed in a separate window when it is started and will no longer fill the entire display in full screen.
