Sorry...blush...We have only one scene and all our Sources are set up under that one scene. You are surprised by that? Maybe I'm missing something about scenes. I am pretty new to all this, so the chances are highly likely I'm causing more work than needs to be done. This is our set up....We have three cameras that feed into a Blackmagic TV STudio HD ATEM. The ATEM feeds the program signal into a capture card. The capture card feeds into the computer for broadcast. We also have a Behringer 1204 USB mixer that feeds two broadcasters into the computer. We will soon be adding another monitor so we can use our Live Score Scoreboard. Right now, we have three graphics that we have to change the properties to for Scores, Inning Number, and Top/Bottom of Inning. With the Live Score, we can combine all three of those into one that will also add more info, but can be controlled very easily on the extended monitor. We have a static opening graphic, an opening video, a couple lower third graphics, a series of commercial videos, plus the mics, Blackmagic properties, the capture card properties, and maybe a few other items...all on the same scene, all in the same Sources panel. We feed the BM Program feed into OBS. When we are ready to change the score, inning, top/bottom, we click on the source and change the properties (now, soon going away to Live Score). When we come to the end of the inning, we click on the commercial we are going to run, then transition to the commercial. As soon as the commercial video starts playing, we click the "eye" to close in the transition window. That brings our live feed back to the preview window. As soon as the commercial ends, it transitions back to the live feed.s And on and on we go through the entire game. Whew...long winded, but I am sure there are lots and lots of suggestions for improvements on this work flow. Oh, during the inning play, we will throw up some bottom thirds, for when a batter is coming to the plate for one of our sponsors. Sigh.... Added: Oh, and we do that with one person in the control room, one camera operator, and two commentators. Forget going to the bathroom during the game.
