I am running the ATEM TVS, all outputting 1080i 50. All works great, except when outputting '50herz' from my Macbook retina display to the ATEM TVS. The video clips or graphics etc, play out terrible, In example, you get frame-rate skipping, choppiness, a video productions nightmare. This however, does not occur when outputting 60herz to the ATEM TVS (59.94) but this means I am not able to use my cameras! What do I do?!?
