Poor quality in zoom meting

I hosted a zoom meeting today with 50 participants.
I used the black magic atem as a webcam source. We had a wired line with 200 mbps down and 700 mbps up.
My problem is that the quality of the stream was very poor.
In the settings statistics tab i could see that our send resolution was 320x180 and fps 15 fps.
Overall cpu usage was often over 90%
On the bandwidth tab it says sending 374 kb/s

The meeting was hosted on a iMac 27 inch 2017.
3.4ghz fourcore intel core i5
8 gb ram 2400 mhz ddr4
radeon pro 570 4 gb graphics

Is this a problem with my computer, my network or with zoom?

Which version?
