Hey Guys! how are you? I really hope some of you could help me....I saw this post about using ATEM Studio + Propresenter together.... I really new to this and I am helping my local church to set up the screens and live broadcasting. We are trying to make the set up as you can see on the picture above... A) ATEM will control the cameras, apple tv signal and propresenter images and videos to broadcast it live B) Propresenter will control the screens and sometimes show the apple tv presentations controlled by the speaker, also the lyrics and bible verses... My questions are: 1) How to make that conection between ATEM AND PROPRESENTER 2) What to use for that set up? What equipment/interfaces? Thank you in advance
