Screen capture of Hopin Stage

Hello

I am currently making preparations for an event using the online platform Hopin as per my clients request. We are using Hopin's built in studio feature as there are too many speakers to use Rendezvous. My client has requested that the event be costreamed to Facebook.

My current strategy for this is using Wirecast's screen capture feature to capture the Hopin browser, and then stream to Facebook from Wirecast.

In my testing I am experiencing quite a lot of dropped frames and video freezing. So I was wondering if anyone had tried something similar and had any tips? Alternatively, if there is another way to do it that I haven't thought of?

Thanks in advance
