Joyoshare Media Cutter, easy to use, but not free.
Absolutely Joyoshare Screen Recorder. It can record gameplay on a full screen and a selected area. the most important point is it won't lag when I am playing a game.
Develop games in your browser. Powerful, performant & highly capable.
As a beginner, I use Joyoshare Media Cutter. It is easy to use. Output video losslessly.
Did you solve the problem? I used OBS before but as you said it is non-user friendly. So I am using Joyoshare screen recorder now. It is compatible with Mac and Windows.
