BMD Desktop Video AJA version 1014.10 3 and higher is currently not compatible with our Playout Engine and therefore we recommend to use Desktop AJA Driver version 1014.92.12 1 until this issue is solved.
When using just:live/play with Blackmagic devices it is not possible to use the DSK-based (Live Key) method to switch from Live Video to Video Playout. Instead the non DSK-based method can be used. In addition, the playout or pass-through of closed captions does not work with Blackmagic devices. Refer to the chapters DSK-based Switch to Live Configuration and Non DSK-based Switch to Live Configuration.
Info
Always use the latest driver provided by the hardware vendor (unless otherwise stated).
Listed here are all UHD/4K devices we have tested with UHD playout up to 30 fps. However it is possible that other devices which also support UHD/4K will work as well
