Woohoo! To start a shoot, you have two options. You can select "New Shoot" in top Menu Bar or click the big green "Start Shoot" in the center of the page.You'll be taken to this screen where you can name your shoot, give a description, and select your output resolution.
Then you can select which platforms you'd like to stream to, or you can do a "Record only" shoot.
Invite your cameras, and start streaming!
