Okay, so, we are going to be filming a show. I will keep the cameras rolling throughout, whilst moving about with them, and will split the clips later on in production. At the start, before the audience arrive, we will line up all the cameras infront of the stage. There is a mic at the back, and a device plugged into the mic mixing board, which controls the on-stage mics. We will use a Clapperboard to get all the sound and cameras lined up. Is there a program that I can use in production that lets me watch all the cameras at the same time (and sound) and line them up? Thanks!
