Taking video is a good first step because you are right then at a minimum the 100+ people that got wait listed can see but also the 1,000s if not 10,000s of people who didn't even know that was a talk they could go to it can now see it. The trick is making it findable- and as with all things digital how to transmit their information faster without the uhs, ahs, ums, laughter, pauses, too detailed explanations etc can be culled to speed up how quickly the critical information can be transmitted. Good work on capturing these talks, probably a thankless job that has helped make the world a more informed place.
