As I explained in this forum post window capture is a very CPU intensive operation. In your screenshot you can see that Skype is running at 100+ CPU and the “Window Capture” Process eats another 80%+. Consider to switch to Screen-Capture if you have a big enough display (or can add a secondary display) to place your windows which you want to capture.
On the other hand: You can make your live much easier if you remove “Skype” from your workflow and use mimoCall instead: https://docs.mimo.live/docs/mimocall This eliminates the need for screen capturing/sound capturing.
We pretty much run MimoLive daily with sometimes 100+ layers and have learned a lot of lessons. Mainly that frame rates drop (and stay? bug?) at a lower FPS / CPU warnings will happen on a good spec mac if it’s doing anything other than just Mimo.
As a result we run NOTHING on the MimoLive mac other than Mimo itself. That includes the YouTube window (or anything involving a browser). Use another machine for any of that.
Also stream and record can be dodgy. NEVER use H264 recording when streaming.
I also find importing video and setting it to “absolute path” other than “import into document” helps.
Doing this was resulted in a fairly flawless broadcast to YouTube/Facebook/Twitter etc:
