We host synchronous educational events in Blackboard Collaborate, and we record them so we can share the events on our website after the fact. We can't always have them captioned in real-time (captioning is an important part of our organizational accessibility policy), so we'd like the option of captioning recordings after an event has concluded. Is it possible to caption recordings in BBC? I haven't been able to see anything indicating that it is possible, but I want to check with this community in case someone else knows something I don't. Thanks in advance!
