Some more capability in terms of custom design here would be a nice feature to add in the future.
I loved the pre-made animation and graphic templates. But we had zero connectivity issues and great results with 5 feeds on a Ubiquiti HD Access point dedicated to the task. Your going to need a good Access Point that isn’t bogged down with other devices for this to work well. I’m suspicious that those who report connectivity issues or unreliable connections are working with inadequately provisioned WiFi environment/AP. Just used the trial version to use 5 feeds to stream high quality video of our school’s Xmas music concert to Facebook.
