Hi, I added that video at https://sling.apache.org/documentation/the-sling-engine/servlets.html#registering-a-servlet-using-java-annotations - we have some good recordings from adaptTo, I think it's worth adding them when they are specific enough.
I haven't looked if there are other talks that would deserve the same treatment but there's probably a few. Or maybe we create a specific "videos" page and point to that where it makes sense. -Bertrand
