Tips for live video streaming DJ sets?

Thinking about starting a regular-ish streams of me (and guests) DJ’ing. I have a cool looking studio and access to some pro level lights. Still need to buy a camera, thinking about a Logitech C922 as it was recommended by a friend who does similar streams I intend to.

Any good tips on the subject? It doesn’t need to look super pro as I’m no pro DJ anyway. Just good enough as the main intention is to have fun and learn some new skills, and to keep the DJ flame alive by not being stuck in a loop and trying something unfamiliar to me.

Tips about how to perform on camera are especially helpful. I’m not a young 'un and being filmed is something I’m not accustomed of. My main fear I’ll just look like an old man standing there and pressing some buttons occasionally. Ie. not very exciting! Then again, I want it to be about the music anyway, not a dance-off.

How about speaking? Since it’s a live stream, probably on Twitch, you can interact with the viewers a bit. If it’s only music I’m not sure if it would be better just to record the mixes offline and then upload to youtube. Live streams are a bit more social.
