I'm thinking about recording my screen monitor while I'm playing some video games and upload the videos both on PeerTube and on YouTube. With a slightly little difference between them: the YouTube version will show messages encouraging the use of adblockers and leading people to PeerTube.
Now I have to find a good software and configuration to record my gameplays on my "potato" computer.
I use OBS for screen recording. While it's not necessarily "simple", once it's set up I usually just fire it up and hit a hotkey to start recording whatever game is running. And I get a lot more control of the result. And there are tons of plugins and support for it out there as it is popular with streamers.
