I'm looking for a few examples of *video* files contributed to Commons recording a lecture, performance, or other *non-Wikimedia* event at (ideally) a library, or a museum or archive. There are several recordings of Wikimedia workshops and talks given at GLAMs, but I'm interested in an example of a non-Wikimedia event held at a GLAM, whose recording was released under a free license and contributed to Commons.
I spent a good half an hour trying various category maneuvers to find something like that, but failed. Do you maybe have an example you are aware of that you could point to?
Imagine a world in which every single human being can freely share in the sum of all knowledge. Help us make it a reality!
