Screen recording in Chrome
Chrome has the most complete implementation of the Screen Capture API, and is the browser this recorder behaves best in.
What Chrome supports
Whole screens, individual application windows, and browser tabs. Tab audio on every platform. System audio on Windows only — see recording on Windows. Pause and resume mid-recording. WebM output using VP9 or VP8 video with Opus audio — see WebM against MP4 for what that means when you share the file.
The sharing bar
While sharing, Chrome pins a bar to the screen with a Stop sharing button. Pressing it ends the capture — this recorder treats that as a normal stop and keeps everything recorded up to that moment, rather than losing it.
Switching sources mid-recording
Chrome’s sharing bar has a "Share this tab instead" button. The recording continues without a break; only the picture changes.
