Lecture recording

What are your preferred ways of recording lectures for online courses? I am working on an open educational resource course right now and want to do a series of mini lectures. My organization uses kaltura capture hosted on mediaspace, but I don’t know if it’s a good idea to have everything on that platform should I ever choose to work somewhere else etc. What does everyone use here? Looking for something as inexpensive (ideally free lol) and user-friendly as possible. Thanks in advance!
