I received a new camera that can output clean HDMI. It is a Canon EOS 250D. I have been experimenting with Open Broadcast Studio and Shotcut. On my Macbook Pro 2018 this seems to be the way to go. Still, on my M1 Mac mini, this does not work well with the video inputs, like the continuity camera from my iPhone. Maybe reinstall it? I don’t think it will fix it, as I am not alone in having these issues.
It’s fun learning these new tools, it works rather well at the moment. The only device I cannot integrate is my oscilloscope from Siglent. Although it has a LAN port, it has no webinterface, only the 4 port models have this feature enabled. It’s a little lame from Siglent to not enable this, as the main hardware of the 2 and 4 ports is the same, I think.
