OBS is advertised as the expert's screen recording and streaming tool, every list on the internet makes it out to be some incredibly difficult program not recommended for newbies.

It's also the only linux screen recorder that works out of the box on Pipewire, records both microphone and system sounds and all configuration was to
1. select recording as my main use case in the setup wizard which is a very verbose English popup, then accept all defaults
2. add a new source, following the instructions written in the box which are also the only instructions on screen after application launch
3. set the output directory (optional) by going to File > Settings > Output > Recording Path, all of which were the first items I guessed. If I had not done this, it would've written everything to my home folder which is a bit dumb but not confusing at all
4. click Start Recording
5. click Stop Recording when done

Some newbie-oriented screen recorders have a more complicated setup procedure than this super advanced experts' tool don't touch without safety gloves and a degree in video engineering.
