Could you please recommend a good free software for recoding my screen. I want to record a lecture and upload it to YouTube. I am looking for a software that can allow me to pause while recording. I want to record the screen and my voice with high quality.
OBS (Open Broadcaster Software) is a free and open source software application for video recording and streaming. It's commonly used by video game streamers for Twitch, Youtube, etc, but is perfectly good for what you want to do and has tons of control options, including setting hotkeys that allow you to start/pause recording (requires version 24 or newer). OBS is supported on Windows, macOS, and Linux.
