Help broadcasting to Youtube using NDI plugin

[DanLit]

Hi, when I'm doing streams, while broadcasting, my participants' images (NDI Sources) change its size automatically and mess up my layout and I can't do anything to avoid it. My guess is: the NDI source changes its size according to the quality of the image im receiving. But I'm not sure that's the problem. Do you have any idea how to fix it?

Thanks!!
