How to fix live view (nikon d610) that turns off automatically?

Question

Video broadcast

Good time!

Friends tell me what can be done. In short, there is a nikon d610, I connect it to the avermedia capture card, then I turn on live view and output it to the OBS - everything is buzzing. Further, after about 30 minutes, live view automatically turns off and the signal disappears accordingly. I read the instructions about Nikon. They write next.


Of course, I tried to connect the camera as a webcam via a DSLR, but the picture quality cannot be compared.

How to be? And of course, advise something if this problem cannot be solved about video cameras and so on. For example, what do you use?
