Footage from 2 of my 3 my Sparks looks like this. When I access the config page, the stills that it pulls look normal. But pulling the footage up on the Tricaster or NDI Studio Monitor, and it looks like this. Lots of colored artifacting. We can see movement of the camera, it just delivers this.
The spark that does work also does this for a few seconds at a time every few minutes. It happens both on Wifi and when plugged in directly.
The sparks have Static IPs/dedicated APs on a dedicated VLAN. The Tricaster and the Sparks' firmware are up to date.
