A local church just purchased a few PTZ Optic Cameras to expand their current two camera setup. When connecting them via SDI to the ATEM Video Switcher there was no video.
This is a common issue encountered when integrating new camera equipment with a video switcher. For example, the very popular BlackMagic Designs range of ATEM switchers that accommodate HDMI, SDI, or both connection types, requires that all video inputs must share matching resolution and frame rates.
In this particular scenario, the ATEM switcher had been configured for a standard setting in the United States: 1080p at 59.94 frames per second. However, the problem lay in the fact that the new PTZ Optic Cameras were outputting a different resolution. While most settings can be adjusted through the software or web interface, the video output settings are actually controlled by a physical dial switch located on the back of the camera.
Consulting the camera’s manual, we identified the correct switch position for 1080p at 59.94 frames per second. We then powered down the camera, adjusted the switch to the correct position, and powered the camera back on. Within a short span of time, the camera appeared in the multiview output of the ATEM switcher.
