My talk from Advancing Bitcoin in March on "sigma protocols and why they matter .." was put up on vimeo a while back (just found out):
They did a pretty good job with the edit imo since they focused on the slides.
Bit of a risky topic, since it's so academic but tried to point out the use cases and use analogies in the first half. The maths lost a lot of people in the second half, understandably.
Casting my mind back on the event: I was impressed with the quality of Elle Mouton's talk on invoices in LN: https://vimeo.com/703262308 , also Tadge's talk was good if you're not too au fait with DLC: https://vimeo.com/703271912 (has some overlap with mine).
