I use SimpleScreenRecorder (which is also mentioned in the footnote of the article). It really is simple to use and light weight. I used to manually select area to record (with border outside the window to record) until I searched and found a solution using ffmpeg to add the border. So, now I just use the select window option. I also use Auto-Editor (https://github.com/WyattBlue/auto-editor https://github.com/WyattBlue/auto-editor) to prune silent portions.
