Mike, it is a massive undertaking to record one meeting, let alone three days’ worth of meetings. And that is just the recording of audio and video, putting microphones on speakers, along with capturing the slides, let alone the subsequent editing, matching of sound and video, labeling, electronically adjusting lighting and sound, and then uploading, plus checking nothing infringes copyright and seeking speaker permissions. It really is a massive job, and not an enjoyable one for a volunteer.
