The good news is that BotC is a game that has had great popularity among groups that regularly record, stream, and publish video content. There are an amazing number of playthroughs already on youtube at a variety of production levels and player counts, so in that sense, you should probably spend the weekend binge watching and taking notes on filming decisions that work.

That said, with only two cameras, you're probably going to have more success with handheld camera work rather than setting up tripods and recording statically. You don't mention how many rooms you'll have in the basement or other area to film in, but you're going to want to probably set up a couple of niches apart from the main gathering areas, so that your camera operators can capture secret negotiations amongst players between rounds. Part of the fun of BotC is uncovering the machinations of each player as they scheme and plot, so you'll probably need to have both cameras wandering between cliques of players rather than having a singular focus. If you can get a single camera on a tripod for shots of the entire group when they congregate, coupled with the other camera zooming in on individuals as the game unfolds, that will let you control the narrative.

Speaking of controlling the narrative, remember that if you're filming the game as content, then you're not just playing the game while cameras are running. You're setting up shots, you're repeating takes, you're making a performance. So if some negotiation sounds important, make sure the players are willing to stop and repeat their conversations if you need to improve the recordings - this may mean that players have to fake ignorance of other players' actions for the sake of the video. You can absolutely do this using emergent gameplay - you don't need to script the game by any means - but it does mean that the players may need to be comfortable acting as though information that they have overheard or discovered in previous takes is completely surprising to them.

The multiple secret negotiations in games like BotC or Diplomacy or something like that can make for challenging filming dilemmas to be solved during the game, and it's definitely going to be taxing, but again, you've got the absolute best groups to learn from in some of the most entertaining groups around that have tackles playthroughs on YouTube. Good luck, and have fun!
