    f you were one of the subjects of research that involved live human subjects , here in the USA , you must fully consent to be researched and you will have the option of rescinding your authorization at any point in the research, but if you are the subject then I am in the dark about how you can also “assist” in the research unless this is an auto-ethnographic study. And if you are “assisting” then it is not clear that assisting implies the role of lead researcher. But all this says that I am unfamiliar with British research (I lived in Britain and completed some post grad research many years ago ) or with the role of research mentors or tutors. My ignorance.  
    regarding the use of video in a class. A good question. I have some concern about researchers using video in a classroom with K-12 students. I have less of a problem with the use of video when adults are involved (I am not sure that K-12 students can give the kind of consent I think might be necessary), but I guess I slightly less concerned if the person using the video “owns” the classroom  and the subjects are adults and are there in the classroom voluntarily and each has given explicit permission for the recording. More ambiguous and problematic might be where a recording was being taken say, for a publicly available webinar , where all participants volunteered to be present and the recording was used by the researchers because they could access it and it was in the public domain…I think my IRB would still require authorization but I don’t know that every institution would require this here in the USA and I have no idea what the rules of engagement are in the UK or in other countries.
    As to the fairness or otherwise of the policies and practices of your university , that I cannot speak to. Nor can I speak to the decisions that were made about your complaint. Sounds like you were treated poorly. Perhaps you should write up your story for possible publication in a journal like the Chronicle of Higher Education or the Times Higher Education,
