Both Windows and Mac have a recorder built right in
You don't need to install any separate screen recording program -- Windows comes with the Xbox Game Bar and Mac comes with its own screen recording tool, so you can capture a lecture or your work screen right away.
Keep your computer running smoothly while recording
If your computer slows down while recording, close browser tabs and background apps you don't need first -- screen recording itself uses processing power, and fewer things competing for it means smoother footage.
Frequently Asked Questions
Can the Xbox Game Bar record regular programs, not just games?
Yes -- despite the name, the Capture widget works on most windows, including your browser or a document program, not just games.
Does Mac screen recording capture sound too?
By default only microphone audio is recorded; unless you select a microphone in the options menu or set up additional software, your computer's internal system sound is not captured.
