2 Screen Recording Tool: OBS Studio
2.1 Introduction
OBS Studio is free, lightweight, open-source software for video recording and live streaming. It can capture, record, stream, and encode video content. It can simultaneously record video from multiple sources, combine it, and stream it to streaming platforms.
Simply put, it can place the screen, camera, and other sources into one frame for recording or live streaming. Here, I only use it for screen recording.

Use the small plus button under Sources to add the screen, camera, and other sources.
After adding the screen, hold down alt in the OBS main interface and drag the edge of the frame to crop it.
