I've uploaded all of the videos (nine videos total from five program items, as I split bids by year and divided the future SMOFCons panel into seated and bids). The longer videos are still processing as I type this, but they'll presumably be all online at the SMOFCon 37¼ YouTube Channel soon.
Note that the order in which the videos appear on the YouTube channel defaults to newest first. To see them in the order they happened, sort the videos "Date added (oldest)." If you want to see the bids for future Worldcons in the order in which they were presented, view them though the Worldcon Bids playlist.
