Screen Recorder
This lesson is part of Web Developer Tools · All levels
Summary
The screen recorder captures images from a screen, application window, or browser tab and stores them as video. You pick the source of the capture, and the browser asks for permission before you start recording. This tool is useful for creating tutorials, demonstrations, or bug reports. The size of the result is affected by the screen resolution, frame rate, duration, and whether the audio is also recorded.
Key points
- GetDisplayMedia is used by browsers to capture screens, windows, or tabs
- Audio systems are only available when the browser and operating system support
- Higher resolution and frame rate results in larger files.
- Close the notification or private window before recording the screen
- The recording can be stopped and saved as a local video file
