Anon,
At my university, you have to swipe your student ID card as you enter the lecture or seminar room. This is how they track attendance.
Recorded lectures are normally a a great resource if students commute and there's been a train strike or delay, as they can access the material later. They can also be useful if you are unwell, as it makes it easier to catch up but they are not a substitute for being there!
I had Covid and missed an important lecture/seminar in the second term and even though it was recorded, you really had to be there to get the most out it. The lecturer had brought items in for students to look at and evaluate and there were lots of explanations done on a board which was not visible in the recording : (
Rather than missing lecture, I would suggest using recorded lectures for revision as you are able to stop the recording, make notes, or go over a particular area that you might be unclear on. By attending lectures, you can ask questions in-person rather than having to send an email later. They are helpful to attend as you can get to know the people in your year.
Hope that helps,
