So by the way, when I was cutting out this piece, I realized that even with my experience working on Macs and online, I can’t find two simple tools: 1) to download just a segment from YouTube. Not the whole multi-hour video, just from 9:30 to 9:45. Somehow no one can do this, they all offer to download the whole thing. 2) Screen recording with system sounds, not microphone sounds. Sounds from the microphone are recorded, but not the system sounds. I know that maybe you could use Zoom and turn on the recording there. But that seems like a rather convoluted way to do it.
In short, if anyone wants some fame (not sure about the money), write a utility for Macs that records a screen or screen segment with subsequent crop/trim, and a tool to download video segments from video hosting services like YT/VK as video files.
It turned out easier for me to download an hour-long video and trim it using QuickTime.
