When you record a lecture, you need to consider copyright issues. Some of these issues do not arise in the delivery of a lecture face-to-face, but do so when a recording is made.
In your lectures you might use materials produced by other people, or you might have a guest speaker. Once you include presentations and material by others who are not TUA staff, the copyright situation gets complicated.
In making an audio recording, you are making a reproduction of the words spoken and any audio material played in the lecture. In making a screencast or video recording, you are making a reproduction of the words spoken and any audio or visual material played or displayed in the lecture.
It is your responsibility to ensure that the material you use and include in the recording complies with copyright. Avoid recording classes where audio-visual materials are being shown or played. If you need to obtain permissions from copyright owners, you will be responsible for this.
If permission is obtained to use copyright materials, it should be lodged with the University Copyright Officer for recordkeeping, by email to firstname.lastname@example.org. Similarly, if you invite a guest lecturer to present, ensure that you have written permission from them to record the presentation.
