How did the Zoom summary work? BTW, i thought of another good use for this cheap video wall converter...PRACTICE! I have been looking for a way to practice and build my skills outside of actual paid gigs. It's impossible to get something worth recording and all the camera people together just for me to practice. HOWEVER, I have 6 channel iso records of a fashion show I recorded on the ATEM extreme. I can get a cheap ($50) 4k video player (or 2) and send ganged-4up videos through the video wall to the ATEM to practice live cutting as if it was a real show (except not able to direct cameras over headset).
