They are subject to the GDPR in so far as they might record students, who might then need to give consent, which could then be withdrawn. In so far as the lecturers are concerned, the lawful basis is likely not to be consent, but rather a contractual obligation, where different rules apply. If for instance, paid actors in films could arbitrarily exercise their right to be forgotten, that would not be a tenable situation. The solution is clearly to not record students in any identifiable way, but there’s no need to avoid recording the lecture altogether. In fact, if the student were not identifiable, I expect it would be perfectly legitimate to record them without any explicit consent. Disclaimer: I am not a lawyer, this isn’t legal advice
