@Rakurri Good video! I also made one last month on the Recorder, but not yet published on my channel (I'm building a buffer of 3 or 4 video in advance).
It is a very difficult topic to explain, and you did it in a better way. So many options, settings, panel, dependency to FFmpeg and technical acronym. I truly realized while doing this video how Krita can be 'DIY' sometimes. But amazing feature, I'm using it all the time.
