The CCC video crew has its fair share of geeks from broadcasting corporations and studio houses. Their combined institutional knowledge about live events and streaming distribution is probably in the same ballpark as that of giant global TV networks.
They also have the benefit of having practiced their craft at the CCC events for more than a decade. Twice a year. (Their summer event is smaller but still fairly well known. Links to talks show up on HN every now and then.)
Funky anecdote: the video crew at Assembly have more broadcasting and live AV gear for their annual event than most medium-sized studios.
