Updating the Black Magic ATEM software to the last version. We were having issues with the computer recognizing the ATEM switcher.
The laptops were not seeing the ATEM control, we thought it had to do with the IP addresses. But everything looked correct.
Although, the update was needed it didn't resolve the problem. We realize that we couldn't have the Wi-Fi able after selecting the ATEM network.
We also practice recording piano and editing it the several takes into one "correct flawless take". We were all super tired so we stopped and decided to continue another day.
