I utilized OBS a lot because I was broadcasting for a long time and didn't have a screen capture device. For me, it also worked. The quality was good. Recently, I also utilized Movavi Screen Recorder Moments to capture movies post-fact, https://www.movavi.com/screen-recorder/. This means that you may play anything. It detects any app from its library of variety, so flash-based apps may not function, etc., and records events up to a few minutes after they occur. Some apps also include an auto-capture capability (sadly, there aren't many applications that enable you to capture things like headlines or similar objects).
