Screen recording used to mean installing software, and most free versions either stamp a watermark across your video or cut you off after a few minutes. Modern browsers removed the need for any of that: screen capture is built in, and a web page can use it directly.
What you can capture
- Your entire screen, for demonstrations that move between apps.
- A single window, to keep everything else private.
- One browser tab, which is the cleanest option for web demos.
Recording good audio
Video without clear narration is far less useful, so include your microphone if you are explaining something. Speak a little closer to the mic than feels natural, and record somewhere without echo. Sharing the computer's own audio is possible in some browsers when you capture a tab, which is handy if the thing you are recording makes sound.
Making a recording people actually watch
- Close unrelated tabs and turn off notifications before you start.
- Decide what you will say first; a thirty second plan saves five minutes of rambling.
- Move the mouse deliberately rather than waving it around.
- Keep it short. Two focused minutes beats ten unfocused ones.
Your recording stays on your device and downloads directly, with no watermark and no upload. That matters when the footage shows internal systems or customer data.
